Hi,
I am working on the v1.7.0 and I am trying to connect two peripheral with the same services to a central. The first works without any problems:
Scanning successfully started

// second one does not succeed

When I unplug / disconnect the first connected, the other one is able to join. Here is my code:

Does anyone has a clue, why this is happening? What means the error-code -111?
