ESP32S3 Light Sleep waken Bluetooth


Is there a way to awaken the board via Bluetooth once it’s gone to light sleep? All I can find is esp_sleep_enable_timer_wakeup and I don’t want that

I tried this

 // Enable BLE wakeup (This needs to be tailored to your MCU's specific BLE library and hardware capabilities)
  BLE.setWakeOnConnect(true); // Wake up on connect, adjust this according to your MCU's BLE library

but no luck

Thoughts anyone? Much appreciated.

Hi there,
AFAIK, It’s not possible. It would be required to have the radio ON and Advertising a Service with a characteristic variable to act as a boolean for on and Off. No Light sleep either.
Best to set a timer and wakeup every so often looking for a connection.?
