How can I know that it's scanning or not?

Hi. I'm using nRF51822AC, SDK12.2.0 as Central.

Q1. Is there any function to know regarding it is scanning or not?

Q2. As your example "ble_app_multilink_central", Does "Scan" stop automatically after "sd_ble_gap_connect"?

Q3. Why do you use "(void) sd_ble_gap_scan_stop();" in "scan_start" function?

I hope your reply.

1. No. I don't think this exists. Use an application timer with the same duration as the scan.
2. Yes. According to the other examples. Scan stops automatically when you connect succesfully
3. Stop scan is sometimes called in start_scan function so that you can call start_scan and not get an error if its already scanning

No worries.

Good luck with your project.
