HM-17 Bluetooth module~

This feature is included only in tasmota-sensors

When compiling your build add the following to user_config_override.h:

#ifndef USE_HM10
#define USE_HM10          // Add support BLE sensor bridge (+5k1 code)
#define USE_IBEACON          // Add support for bluetooth LE passive scan of ibeacon devices 

HM-17 and HM-16 are a Bluetooth BLE V4.1 module based on TI CC2640R2f chip. Manufactured by Jinan Huamao


Check whether your module is communicating properly over its TX/RX pins and that it has the required firmware (firmware V120 or V110). Only when you're sure everything is ok proceed with the configuration.

Tasmota Settings for iBeacon~

In the Configuration -> Configure Module page assign:

  1. GPIOx to iBeacon TX (168)
  2. GPIOy to iBeacon RX (169)

When first connected HM-16/17 is in peripheral mode. You have to change it to central mode using commands Sensor52 1 and Sensor52 2.

If you have supported iBeacon Bluetooth devices in range, they will be discovered and will start to populate the webUI with data:
