ESP32 Forum

Hi everyone:
I want to know ESP32’s classic bluethooh and wifi Whether it can coexist?
I only add wifi connect opertion to a2dp sink demo. It aways appear "bcn_timout,ap_probe_send_start", I guess that is cause by classic bluethooh interrupt too long to wifi bcn. And It will cause ESP32 reboot.

p_probe_send over, resett wifi status to disassoc
I (102478) wifi: state: run -> init (1)
