Peripheral send rejection on update connection parameter after Master accepts it and send PARAM_REQ.

[mahmoud_k_elkas]

Hello everybody.

I'm using QN9080 as a peripheral, I implement connection parameter request using "APP_GapcParamUpdateCmd" API after Master accepts it and sends PARAM_REQ, peripheral send rejection on PARAM_REQ to master due to Collision. I read in specs that the master who sends rejection if there is any collision happens.

I have a couple of questions.

1- Why peripheral rejects that after master accepts?

2- I can catch the error code when the Master accepts/rejects the connection parameter.
    is there any way to catch the error code if peripheral sends it?

Any help?

Hello, 

How are you implementing the flow of the code to start the connection? Are you using some examples as a base?
