BLE Advertising Crash
Posted: Wed Nov 27, 2019 2:52 pm
Hello,
I am currently running into an issue with BLE advertising causing a core panic. This is 100% reproducible with minimal code.
It will always crash after attempting to start advertising after the controller has been disabled and re-enabled.
After setting up BLE, the following task can be run to cause a crash (Note, some code has not been included, but its the ble_adv example with some minor modifications).
Here is the monitor output when it crashes
There has been an open issue on GitHub since December of 2018 with this exact issue, but I'm wondering if anyone has worked around this before?
Thanks.
