Final Project, ESP8266 and the Arduino IDE Part 10c: IOT Website. There are many other similar apps available such as B-BLE. You need to connect to each node one at a time. // SerialIn_SerialOut_HM-10_01
The secondary Arduino simply checks for a “1” or a “0” and if it finds one of them it either turns the LED on or turns the LED off. Note that in V700 onwards: Depending on the power on and the on-connection settings, the LED may come on when the remote HM-10 is powered or when a connection is made. HM-16/17 speed is about 3-8KB/seconds, HM-10/11 in automatic sleep mode 50~400uA Predefined services and characteristics are ones where the UUID and the name are set by the Bluetooth governing body. Again, I can’t remember the details but the docs are available on the Jinan Huamao website. This file will be received by students through an Android app(that we would want to develop). This only works when there is a connection. some example of use? I'm pulling my hair out because I'm trying to have it automatically pair when it gets in range, just like many other bluetooth devices, but it just doesn't work. Is another 2 byte value or string and is meant to identify individual beacons. I have a CC41-A clone, and my Pixel 2 nor my wife’s Pixel 1 (both on 8.1) won’t even find them in BLE scanning apps. RX-TX pinini doÄrudan baÄlayabilirsiniz eÄerki Vcc pinini 3.3V ile besliyorsan. Set the output of a pin HIGH or LOW. Sometimes it may require to change the default settings like baud rate, or master/slave role of the module. – 9: 1285ms If fast scans is something you need it may be better to look at more high end modules, especially ones that can scan in the background. I want to save power and have set the module up with auto sleep with PWRM0. Could you maybe point me in the right direction so that I can advertise the BATT info in the response data of AT+DISA? I will make automatically discovery every 8 second, I try in arduino but no respond. Is it possible to encrypt the connection? I found some info but I can’t figure out how to send it from HM-10, ‘Internet search keywords “iBBQ”, “BLE 4.0”, “Bluetooth BBQ thermometer” ‘the client caracteristics configuration descriptior has to be configured in order to read the data. I have the remote HM-10 powered from the Arduino but in practise you’d use a separate power supply such as a battery. -Removed AT+COMP command // 48 is the ascii code for "0"
I want to discover the ble beacons instantaneously or less than a second. Have you looked at this? Start the app, find and connect to the HM-10, expand the custom service and you should now see 2 custom characteristics: In the FFE2 characteristic section click the W button and a text input window pops up. BTserial.print("AT+CONA81B6AAE5221" );
BTserial.begin(9600);
After plenty of testing, the command AT+SET_WAY did the trick for me. I’m running into an issue with compiling your serial sketch example. The sketch on the master Arduino uses 3 AT commands to set up the Central HM-10 and start the connection. I have the remote HM-10 powered from a bread board power adapter but you could also use a battery.
This command is set send interval. Do you think it is possible to recover data from the miflora, if yes do you have some infos to give me? Remember when using other sketches or a USB to serial UART adapter to set line endings to “No line ending” at the bottom of the serial monitor. {
Works with all types of Arduino and competitors. // Read from the Serial Monitor and send to the Bluetooth module
When there are 2 or more modules and one is in Central mode it will search and connect to another HM-10. Set pin status after a connection is established. I have ran your code and can get the serial monitor to display text i send through my phone to the MLT-BT05 however i can’t get the AT commands to work. First, lets use an Android device to read the services and characteristics from the HM-10. Here I am using BLE Scanner. ‘initiate-login :: It may also be worth while checking out the HM-sensor firmware. Hey I also purchased a DSD tech HM10 and can’t seem to get any AT responses. If I get time at the weekend I will try a few experiments. Would you know how to do this? ");
I tried AT+SLEEP in HM10. If not please ignore the below. double check line end characters AT+RESET //reset Many thanks again. Of course, if there are only 2 modules it does not matter. The “38A3” are the last 4 digits of the mac address. Do you know how to get the exact time of arrival of the signal of each nearby device using the AT commands? The LDR is connected to peripheral HM-10 pin PIOB. firstly, thanks a lot for the sheet. My problem occurs because I am unable to send AT commands when the connection is established. Communication diagram: switch_State = state1;
Note: AT commands only work when the HM-10 is not connected. To send text from the app to the serial monitor, tap the Write icon and enter something in the popup text box. Pins set using BEFC can be changed later using AT+PIOxv. Double check the baud rate. It can be used to group together related Beacons as well. HM Bluetooth module datasheet -----Last Version V524 2014-03-08 6 3. If you are using Win7 or later you may need to run the app in admin mode. {
Nothing else is required.
If you are using an original HM-10 you do not need ccloader just follow the instructions above. -Added AT+NTOIFYOFF command I was sort of assuming that one would use AT commands to instruct the HM10 to read the one wire data from the DS18b 20 on pin 34, then attach that data to the advertising data, but can this be done once, or does this AT command have to be sent to the remote HM10 every time you want the temp data? {
Firmware I haven’t tried though. It has been a while since I used the HM-10 but if I remember correctly the battery information is transmitted only in the advertising data. Hi martym The best option, if you have access to the other device, is disable password pairing. For the battery, check the data sheet. How do you think I can accomplish this? ‘@RealtimeDataEnableMessage: (:byte[]) { 0x0B, 0x01, 0x00, 0x00, 0x00, 0x00} Your email address will not be published. x is a value from 0 to 8. -Added AT+FINDALLCHARS? queries what mode the device is in. Power on the HM-10, you can use an Arduino for this but all we need is 5V to HM-10 VCC and GND to HM-10 GND. //
Blinks mean something wrong with the connection between Arduino TX and HM-10 RX, Thank you Martyn, my problem was with the voltage divider for the RX pin of the module. {
AT+ DISC? Bluetooth 4 BLE returns the actual voltage in the form of a 3 digit float. I had some issues getting the HM-10 fully working with other modules. HIGH to LOW. – Check that you have “No line ending” selected at the bottom of the Serial Monitor. Here the sketch takes care of the line end characters for us. boolean NL = true;
Device names can now be up to 29 characters. But here we are going to learn about HM-10 BLE 4.0 with Arduino Board. Have you reached any result about return values? A litle later we control an LED with just a HM-10, no second Arduino. The HM-10 is a BLE module and the phone will only connect to it when an app is actively using the connection. para1 value: 0 ~ 6; Default: 6(6000ms); So if I try AT+RSSI when the devices are connected nothing will occur. AT+ROLE? Really helped! I’m currently struggling with a functionnality I don’t succeeded in doing with HM 10; I would like to read characteristics from a distant devices throught HM10 (a mi flora). You pages have been invaluable to me, but I have a problem I am unable to resolve. AT+RENEW – restore factory defaults. One question regarding the suitability of the HM-10 for my first project: Recently I bought some modules with firmware v604 and all seem not to be able to wake through uart. all I get back is OK+DISCOK+DISCE with absolutely no connection data. My hm-10 as a slave is connected to my arduino and i use my iphone to connect to my hm-10. // BT GND to GND
Since I am using the HM-10 on a breakout board that has a 3.3v regulator I can connect 5V VCC directly to the VCC pin on the board. Well it looks like we're both trying to do the same thing :P. As jmw6773 pointed out, you can't do that due to HC-05's hardware limitations.
I have been meaning to add this to the above guide but have not found the time yet. double check upper or lower case ‘The iBBQ is a Bluetooth LE Gatt Device ‘@SettingsData: @uuid16{0xfff5} @write is where control messages are sent BTserial.write(c);
The Arduino terminal works because it buffers the entire command line, then sends all of those characters out with no intervening time. The on board LED blinks when waiting for connection. Is this correct? Also I got a response for huamo about who they recommend for supplier.
Read the voltage on a give pin. I also appreciate all comments and suggestions on how to improvise design or new ideas. See above. I wrote a pluging for Unity to connect to Bluetooth Low Energy devices. Once you have this you know the scan has finished. Once set the baud rate is remembered and does not change when the module is reset. Check the data sheets for details. I would be most grateful for any assistance you could provide. c = BTSerial.read();
This is a 2 byte value or string that can be used to create a small group of more closely related Beacons. //
Yes it does! As a simple example to get started we will turn an LED on and off. I don’t have recommanded suppliers. Note the double question marks. This is the small board. I have used diodes and also power regulators but prefer resistors. When the HM-10 is used remotely and the AT commands are received over wireless, the pin control commands work a little differently. I struggled a bit on this one. They also have a different firmwares. Serial.println(" ");
I am wondering about the possible operation of the OH1 sensor with an HM-10 module in master mode. //
}. ‘————————- My hope is to connect the two devices and the check the RSSI value of the BLE device when they are connected. Hello Martyn. – 1: Only allow last device connect in 1.28 seconds The UUID is divided in to 4 parts and each part is changed separately using; AT+IBE0, AT+IBE1, AT+IBE2, and AT+IBE3. Descriptors: BTserial.begin(9600);
Hi Ivan. Alex. * AT+UUID Get/Set system SERVER_UUID . Try one of the BLE scanner apps such as LE Explorer at https://www.microsoft.com/en-us/store/p/bluetooth-le-explorer/9n0ztkf1qd98 or google “Windows BLE scanner”. Tap the CONNECT button to get the app to connect to the HM-10 and start reading its properties. The problem I’m having is tat while power is on, its connected to the UNO. For example, the furniture department. This save quite a lot of power and this option should be used if you are creating a simply iBeacon. For this example I am using 2 HM-10s; one connected to an Arduino as before, and a second simply powered. P3: Rest Data Length It can be flashed back to v540, though. The BLE device is the peripheral device. Have you noticed this behaviour? 0. Using the HM-10 with App Inventor 2: Arduino, HM-10 and App Inventor 2. since i need more throughput, but would like to stay with low cost chinese devices i was wondering if u had a chance to evaluate the hm-16, which is also cortex m0 based and claims to be faster, HM-10/11 speed is about 2KB/seconds The upgrades went well, however EVERY other version of firmware beyond 5.4 would not allow my phones to connect. I did some TTFs on 3 HC-05s by connecting the RX pin directly to 5V and then ran a a serial send in a loop. The second custom characteristic only has a WRITE property no READ and the value of this characteristic is sent to the serial UART connection the same as the FFE1 characteristic. To make a connection we: I am trying to build a project with BLE (HM-10). This Bluetooth Low Energy 4.0 Module utilizes a HM-10 module to provide your Arduino with an easy to use wireless link between your Arduino and any compatible iOS or Android (4.3+) device. If iâm not wrong, the library used in your code use the pin 8 & 9(Rx Tx) for Uno but if you have a mega 2560, pin 8 and 9 are mapped on pin 46 and 48 for the mega. {
If this works go back to the hardware serial. Set the PIO pin control mode. what i need to do in order to send data to the HM-10? 2 – with usb pads without the extra crystal The modules can be paired using the default pin 000000 (unless you have changed it of course). – If Notification is enabled in the APP, bytes sent by the device are correctly reported by the APP. {
5 – read data Serial.println(" ");
All the services on the HM-10 are predefined except one. ‘ ‘To unsubscribe send x0000 to FFF0/FFF4 Then it can connect. x = a value from 0 to 9. This is cumbersome but possible. Problem activating HC-05 AT command mode with Arduino Uno Bluetooth shield. Controlling a Solenoid Valve from an Arduino. // Pins
-Added AT+CHAR command are you trying to send AT commands over the BT connection? Did you manage to make a piconet? On the first Arduino we have HM-10_Example_01_simpleLED_Central. I will make a algorithm if hm10 connected with other hm10 will turn On the LED but if disconnceted will turn off the LED. Since the remote device is already set up we do not need to change it. Hi, great tutorial and I’m moments away from purchasing a couple of these things but do you happen to know what happens to any altered pin states should the central mode device lose power/connection with the peripheral device in a remote control situation – say I remotely set a normally low pin to high on the peripheral device to turn on an LED, will the remote device then set that pin low again immediately (or at least back to its confgured pre-connection state?) Yes, you can use 3.3v output of arduino for Vin of Hm-10. I had two modules with two Lenovo tablets running BT Serial Terminal and each connected to a module but when one disconnected, there was a GATT error when trying to connect. BLE is not an upgrade to Bluetooth Classic, it is a different system with different intended uses. // BT VCC to Arduino 5V out. I can’t find a class but the the RF Power is : -23dbm, -6dbm, 0dbm, and 6dbm. Just here sharing my experience that may help somebody reading comments, or maybe you (Martyn) could update the post with my hint! Used for connecting to later. This means you can use the sketch without changing it. Going further, I tried upgrading the firmware as Martyn suggests… This is the same as the CC2540 except it is lower power and has a shorter range. BTserial.begin(9600);
Hi, I don’t see the AT+PWRM on my AT-09, is there something I can do to fix it? To me if they were fakes they would copy the firmware. Serial.print("Sketch: "); Serial.println(__FILE__);
-Added new function used to support different brand BLE device AT+RESP Have you had any experience with modules having the same MAC, being on at the same time with multiple phones trying to connect and communicate at the same time? The breakout board has a 5v to 3.3v convertor allowing 5V to be used. Not sure if this is just for now or permanently. Martyn, P5: 2 Bytes, Write property. Serial.println("BTserial started at 9600");
I had an older HM-10 where AT+SBLUP does not work. {

In order for the OH1 sensor to send the heart rate value it must first be connected, then send 0x01 to the “Client Characteristic Configuration descriptor” according to the developer documentation: //
Description Additional information AT-09 BLE Bluetooth 4.0 Module TI CC2541 (HM-10) The AT-09 is a module that contains a BLE chip (a CC2540/CC2541). I’ve been working with a couple of Chinese clones (I’d like to call imitations). It would be nice to get the last sent data with a “read” instead of a notification. more details there: This makes them ideal for hobbyists like me. I saw that your expirience on HM-10 is very high and I thought perhaps you could help me indicating an app. Therefore, I decided to redo the guide. The module with address A81B6AAE5221 is now set to Peripheral mode and set to allow AT commands over wireless. The STATE pin is HIGH when there is a connection. Can we change descriptors on some services. see Bluetooth module HC-05 and HC-06 are still very popular among makers and hobbyists as they are cheap and easy to interface. CUSTOM CHARACTERISTIC (R, W, N): OK+DISA –> Search start delay(1000);
– 5: 546.25ms how to scan the other hm-10 more than 2 devices in one time? The LED becomes solid on when a connection is made and returns to blinking when the connection is broken. -connect to the Mi flora adress in master mode with AT+CON –>OK Thanks, Tony, If you found any solution please share it. Im trying to run this hm10 module on the MEGA. // Echo the user input to the main window. Open up the “CUSTOM SERVICE” section and turn notifications on by tapping the icon. // Arduino D9 (SS TX) - BT RX through a voltage divider (5v to 3.3v)
I am using the HM-11 for a project and having terrible luck getting it working. I found that I do not need to pair when TYPE is set to 0 (not need pin code). Now, in the BLE Scanner app, connect to the HM-10 by tapping the CONNECT button. I have found them quite helpful. trying to send AT+SEND_DATAWN exactly after AT+CON but no respond from the module. If i do the same with a HC-06 module everything works just great! Sketch: HM-10_Example_03_MODE2_LED I have a couple of AT05 boards that will only connect to each other for this reason. // Pins
To scan for other HM-10 modules use the Discover command AT+DISC? and i paired with Bluetooth already. {
Thanks! How can I do this? I have a problem, when i wrote command AT, then i saw it in value without response. This is a very simply example, when a button switch is pressed a remote LED comes on. The actual HM-10 is a 3.3v device. However, I would also like to be able to load new sketches to the Arduino over the air, using my PC’s bluetooth dongle. Thanks! AT+PACK[P1][P2][P3][P4][P5][P6] Good luck.
Confirm the connections are correct and the HM-10 is reponding by using “AT” and then revert the HM-10 to default settings with “AT+RENEW”. c = Serial.read();
I am trying to connect HM-10 with VNA2-BT Adapter (BLE to CAN).I am unable to discover and connect VNA-BT. AT+IBE3EEFFEEFF sets the UUID forth part to EEFFEEFF. When updating from below V700 the HM-10 will need a factory reset before the new settings are activated. It will remain in upload mode even after cycling the power. I do not have Android 8 so have not tried and cannot confirm. I'm building a project with Bluetooth 4.0. I am interested in trying to connect a DS18b 20 to pin 34 (?) Like the HC-05, the HC-06 module can reach a range of up to 9 meters (30 ft). Currently I have HM10 TX to Ard RX and vice versa, but no voltage divider and I find that the BLE scanner I am using ‘LightBlue’ can see all the data that the Arduino is generating.
