ESP32 BLE OTA issue

Postby ansonfever » Fri Mar 31, 2023 9:30 am

Hi,

I am currently using IDF v4.3.3 and ESP32-WROOM to build a device as a BLE peripheral.
Under BLE OTA process, I found that the BLE driver sometimes hang up during receive "L2CAP fragment".
The device does not send out "Empty PDU" and even disconnect when the supervision timeout is reached.

Attached the sniffer log which show the phenomenon when the device is hang up.

Does everybody faced this issue before?
