ESP32 works, but I assume it’s too power hungry ATM.
You can try the nRF51/nRF52 series. The setup is very similar to Micro:bit:

Regarding LowPower mode - we don’t provide it out of the box, as it is very application-specific. So you’ll have to put some efforts to get it working.

Thanks for reply. Can esp32 only turning ON when BLE connection request? the bbc microbit do it.
