BLE set a timeout for client.connect()

[nathan-casabieille]

Hello,

I am currently programming an esp32 to retrieve data from all surrounding bluetooth devices.

First, it does a scan, then it create a linked list and connect to all the detected devices one by one, retrieving each time a data.

Everything works perfectly for tens of minutes, but randomly, at one point the program always hangs while I execute the command pClient->connect(pAddress); while trying to connect to one of the detected devices.

Knowing that this is a blocking function, how can I execute it, and move on to the next one if after 30 seconds it is still blocked?

Any answer would help me greatly, thank you very much!

Hey Blue,
Find out the condition before which the connect hangs and reinitialize the client and go through the complete seq of establishing the conn
