Smart-BMS-Bluetooth-ESP32.ino

/**
  Program to read out and display
  data from xiaoxiang Smart BMS
  over Bluetooth Low Energy
  https://www.lithiumbatterypcb.com/
  Tested with original BLE module provided.
  Might work with generic BLE module when UUIDs are modified

  Needs ESP32 and graphic display.
  Tested on TTGO TS https://github.com/LilyGO/TTGO-TS

  thanks to Petr Jenik for big parts of code
  thanks to Milan Petrzilka

  known bugs:
  -if BLE server is not available during startup, program hangs
  -reconnection sort of works, sometimes ESP reboots
