How to turn off and restart the BLE core in STM32WB50

MPian.1 · ‎2021-06-01

I'm working with a STM32WB50. To save energy i have to turn off BLE when i don't need it and turn on when i need it.

You do not need to start and stop the BLE core. If you do not send any commends to the BLE core, the BLE core remains in low power STOP2 mode.

So, at the end of the current command being processed by the BLE stack, The M0+ core enters STOP2 mode.

If you want the BLE core not to respond to any connection, just close them.

Otherwise during no RF activity periods, the M0+core is in STOP2 mode, which is consuming very few power, around 2uA.
