BLE abort in getCharacteristics #736

Open yuyi1005 opened 5 years ago

yuyi1005 commented 5 years ago

My program is similar to the BLE_client example, collecting data from a BLE server which supports only "notify" characteristic, but it crashes on finding characteristic.

I am using the latest code in esp32-snippets updated 2 days ago (commit 45fcc07).

My code works almost well before updating the BLE module, and I didn't change anything in my own code (just update the BLE module and recompile).

Here is the log:

Core Debug Level: "Error" Found our device! Forming a connection to 5a:40:00:01:8a:8a Connected to server Found our service

There is a lot Stack smashing problems, but i didnt have any so i cant find the reason without proper backtrace decode. Sorry for inconvenience.
