BLE Scanner Android App
- Once the installation is completed, open the App and enable Location and Bluetooth permission.
- Scan for the bluetooth devices. The name of HM-10 BLE 4.0 is MLT-BT05. The default pairing code for MLT-BT05 is 123456789. So once connected, you are ready to go now.
How do you use the HM 10 Bluetooth module?
How do I reset my Bluetooth HC-05?
Make sure the HC-05 module is NOT PAIRED with any other Bluetooth device. Re-connect the Arduino Uno 5V wire to the HC-05’s VCC (5V power) pin. The HC-05 LED will blink on and off at about 2 second intervals. Now the HC-05 is in AT command mode ready to accept commands to change configuration and settings.
What are the parameters of the HM-10 Bluetooth?
HM-10 DataSheet. 1. Product Parameters .

Why does my Bluetooth module keep losing connection?
I’m able to pair with it using an Android device and passing the pre-defined PIN. Based on the UART return, the pairing is successful (module returns OK+CONN – means a connection was established) However, after a few seconds (2-3), the UART receives OK+LOST; means the connection was lost.
How to find MAC address of Bluetooth module?
PS: MAC address of your module can find with ble scanner code or with AT cmd: on my firmware AT+ADDR or AT+LADDR About UUIDs usage: not sure, but in my case, i find it with next AT+UUID [Get/Set system SERVER_UUID] -> Response +UUID=0xFFE0, AT+CHAR [Get/Set system CHAR_UUID] – Response +CHAR=0xFFE1.
What does entity of BLE mean in HM-10?
I’m not sure, but HM -10 don’t support rfcom. It’s mean that you must use GATT functionality for communication. Entity of BLE is usage of minimum data package as it possible, so BLE don’t hold the connection all times and use something like statuses [attributes].
