* Xiaoxiang BMS to MQTT via WiFi
|
||||
* by Bas Vermulst - https://github.com/BeaverUI/ESP32-BluetoothBMS2MQTT
|
||||
*
|
||||
* Based on original work from https://github.com/kolins-cz/Smart-BMS-Bluetooth-ESP32/blob/master/README.md
|
||||
*
|
||||
|
||||
=== configuring ===
|
||||
Using the #define parameters in the CONFIGURATION section, do the following:
|
||||
1) configure WiFi via WIFI_SSID and WIFI_PASSWORD
|
||||
2) configure MQTT broker via MQTTSERVER
|
||||
3) set unique node name via NODE_NAME
|
||||
4) ensure the BMS settings are OK. You can verify the name and address using the "BLE Scanner" app on an Android phone.
|
||||
|
||||
|
||||
=== compiling ===
|
||||
1) Add ESP-WROVER to the board manager:
|
||||
- File --> Preferences, add to board manager URLs: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
|
||||
- Then, Tools --> Board --> Board manager... --> install ESP32 package v2.0.3 or later.
|
||||
|
||||
|
||||
2) Install required libraries:
|
||||
- MQTT (by Joel Gaehwiler)
|
||||
Install via "Manage Libraries..." under Tools.
|
||||
|
||||
3) Configure board:
|
||||
Select Tools --> Board --> "ESP32 Arduino" --> "ESP WRover module"
|
||||
|
||||
4) Connect board via USB.
|
||||
|
||||
5) Configure programming options:
|
||||
Select appropriate programming port under Tools --> Port
|
||||
Select correct partitioning: 1.9MB app (with OTA) or 2MB app with 2 MB SPIFFS - otherwise it won't fit
|
||||
|
||||
6) Program and go!
