Wake up from sleep using BLE

[felipe.barahona]

Hi community,

I'm wondering if there is a way to wake up ESP32 from BLE (I'm new with ESP32 and ESP IDF).

I'm working on a battery powered project and the only way to wake up the ESP should be through a reception of an BLE packet (a beacon, for example?).

Is this possible?, or should I find another way to wake up?

I found this documentation : https://docs.espressif.com/projects/esp ... p_source_t where says that a BT is a wake up source (check struct esp_sleep_source_t), but I have not been able to configure it.

If someone is able to give me some information, I would be very grateful.

Regards
