# Derived work based on https://github.com/reaper7/M5Stack_BLE_client_Owon_B35T by reaper7.
|
|
# AI (ChatGPT (GPT5.5), Qwen3.6) has been used to adopt the Arduino sketch to ESPHome.
|
|
# Ported to M5Stack Core2 due to memory constraints.
|
|
# Integrated atorch ble proxy functionality from https://github.com/syssi/esphome-atorch-dl24 by syssi.
