BLE Notification Function Call Causes Crash. Can anybody understand this register dump and what would cause it?
Posted: Mon Jan 18, 2021 7:58 pm
I am trying to get BLE notification data from my Beetle BLE and am struggling to connect to the notify service. When using multiple BLE scanner apps on my phone, I can subscribe to the notifications and see the data flow in, but when I try to run the ESP32 scanner code, it crashes when I call pRemoteCharacteristic->registerForNotify(notifyCallback); I also call this function right after I call if(pRemoteCharacteristic->canNotify()) so I know that the notify byte is set.
When the ESP32 gets to the registerForNotify line, it get this error:
Does anybody know why this would happen?
Here is a link to the code that I am using:

When the ESP32 gets to the registerForNotify line, it get this error:
