Connection parameter errors catching

[Mahmoud Kassify]

I'd like to ask if I request to update the connection parameters via "sd_ble_gap_conn_param_update" and the center for any reason reject the connection parameter.

How can I catch the error code?

For example, if the central send rejection with an unsupported param value or collision or any other reason, how can I know the error code in the nordic due to a request to update the connection parameter?

There are no specific error codes, you need to check the connection parameters when receiving the *CONN_PARAM_UPDATE event whether they were updated or not.
