powermeter-logger_bluetoothbms

Connects to Xiaoxiang BMS (www.lithiumbatterypcb.com) via Bluetooth and sends its data to a webserver over WiFi.

This work is based on https://github.com/BeaverUI/ESP32-BluetoothBMS2MQTT.

Required stuff

• ESP32 (with Bluetooth and WiFi). This code was tested on "ESP32 NodeMCU Development Board" / ESP-WROOM-32, but should work with any ESP32.
• HTTPS webserver, running https://github.com/eenemeenemuu/powermeter (or any other software which accepts the same transmitted data).

Programming the ESP

• Install the Arduino IDE
• Configure the IDE (see code for more info):
  • In preferences, add the board manager URL
  • Install the required libraries
• Open main.ino
• Configure the programmer:
  • Connect the ESP32 board via USB, select the correct COM port
  • See programmer-config.png for the other settings

Configuring

To configure the module, change the values in config.h to your needs, especially:

• WiFi (SSID + password)
• external host (server + path + key)
• BLE name and address
