Central keeps waiting for a connection , does not timeout

Hi Nordics

https://devzone.nordicsemi.com/f/nordic-q-a/22595/can-not-received-ble_gap_evt_timeout-event-when-connect-timeout/88877#88877

Referring to the above post, I am also going through the same issue that the central when running sd_ble_gap_connect, does not know when to timeout and simply waits forever to make a connection. I was expecting it to provide a timeout event or something so that i can make a decision based on that , and NOT keep waiting for making a connection. The above post's solution indicates that the SCAN_TIMEOUT has to be set to a non zero amount. My question is if so, does that mean BOTH scan and connect depends on the same parameter, there is no way to make these two functions behave independently ?

This makes no sense, since I would want to keep scanning forever and not timeout, meanwhile for connection i DO want a timeout to happen.  Please advise if there is a way to set the connection parameter to timeout while not affecting the scanning.

thx

Hi, 

Which version of SDK/Softdevice are you using? 

I would suggest you take a look at GAP Timeout sources and nRF5_SDK\examples\ble_central\ble_app_uart_c how to handle the timeout on Central connection.
