Load Prohibited panic within BLE

Posted: Wed Oct 24, 2018 5:30 am
by etha890
Using IDF 3.1

I am observing a Load Prohibited unhanded exception, whilst running some ble and wifi code. Analysing the core dump yields the following.

The crash takes some time to occur and seems that the function which is causing the crash is within the IDF (L2CA_CheckIsCongest).

Any ideas?

Re: Load Prohibited panic within BLE

Posted: Wed Oct 31, 2018 9:46 pm

I am still suffering from this issue, I do however have a better thread trace which has pointed me into the place were the crashing is always occurring.

When calling the function esp_ble_gattc_write_char_descr() in the callback to ESP_GATTC_REG_FOR_NOTIFY_EVT the data which is passed through to this function is correct as I have confirmed with a log message, however the data which it is actually pulling in is somehow corrupt as shown by;

#1 0x400e94c6 in esp_ble_gattc_write_char_descr (gattc_if=3 '\\003', conn_id=0, handle=38086, value_len=16304, value=0x0, write_type=(unknown: 0), auth_req=auth_req@entry=ESP_GATT_AUTH_REQ_NONE) at C:/msys32/home/EthanA/esp-idf-

The handle should be 16 and the length should be 2 and value 1.

In some cases it takes up to 12 hours for this corruption to occur, which is making it quite troublesome to debug.
