GATT_CLIENT example

Postby AdySan » Tue Jan 10, 2017 6:22 am

Sorry for the rather noob question, can someone give a short explanation of how the GATT_CLIENT example in esp-idf is intended to be used?

The GATT_SERVER is straightforward, I can run it, connect to it from a phone, read/write to the two services which are advertised. But I'm not sure if/how the GATT_CLIENT example is meant to make a connection to the GATT_SERVER? It does scan and find the GATT_SERVER, but how does one trigger it to make a connection and read/write chars?

[UPDATE]

Looking at the serial debug, I see the following btc post failed error
