Bluetooth wifi coexistence problem

Postby lewishe » Thu Sep 27, 2018 10:54 am

I added the wifi startup code to the play_bt_music_example in the original adf, but I didn't operate the wifi. When I connected the Bluetooth to start playing, after waiting for 5 seconds, the cpu was reset by wdt, when I removed the wifi-related function. Everything is normal, here is the error message:

I checked the adf getting started guide, I have already opened the PSRAM support relatively, I believe this is not a problem of insufficient memory, it should be related to the opening of wifi, when I turn on wifi, Bluetooth connection, wifi will be disconnected.
