Hi,
I’m wondering if there is way to wake up ESP32 from BLE connection.
I want to put ESP32 in deep sleep but it can wake up when BLE connection established.

Please advise.

thank you.

Hi.
I think that is not possible at the moment.
You can wake up the ESP32 using a timer, touch or other external wake up. I don’t know if it is possible to do that using the ULP (ultra low power processor), but I haven’t found anything about this.
If you find a solution, please share, this subject would make a good tutorial.
