Time Required for Pairing two cc2540

I want to use two cc2540s for my application. What I want to know is the total time consumed (in seconds/milliseconds) by the BLE chips in the pairing process(i.e. to send connection request, pairing process and connection established) if the pairing process can be Just Works.


Thank you in advance

    Hello. This is dependent on the connection interval. I've attached an example sniffer capture of what a sample Just Works pairing process looks like (open with TI packet sniffer). From pairing request being sent to security being enabled took 12 connection events.

    In this example with a connection interval of 7.5 ms, this means 90 ms.
