BT SPP acceptor error: "Cache disabled but cached memory region accessed" while pairing

Postby newsettler_AI » Mon Jul 23, 2018 4:24 pm

Hello,

I'm running modified SPP acceptor example and WiFi in AP mode simultaneosly.
Aslo there are deployed UART (GPIO 5, 18) and some LEDs (GPIO 13, 15, 21, 16, 17).

I cant robustly pair via Bluetooth and esp32 from android tablet (i.e. I'm able to connect after 2-3 retries).

Here is log:

Code: Select all

Rebooting...
Any ideas?
