Scanning with selective channel(s)

Question

Hi, 
 I know that this question has been asked before but it seems like the answers are pretty old. 
 I have a need to scan on one channel only to receive advertisements, just like described here: 
 devzone.nordicsemi.com/.../ 
 The advertising device is designed to send on one channel only and currently I seem to miss a lot of the packages sent. 
 I'm using nRF52840, S140 5.0.0-2.alpha and SDK 14.1.0 
 Is there now some way of doing this using the SDK features? If not, what may be the best way of accomplishing this? 
 Thanks!

I chose to download ble_app_proximity - Observer.zip posted by Hung Bui at devzone.nordicsemi.com/.../ 
 With some minor tweaking (due to compile errors), it seems to work fine with S140. I also removed the increment of the channel variable in ll_scan.c to have it locked on channel 37.

No change so far, Nordic BLE stacks don't support this feature (yet?). You have obvious choices: 
 
 Play with scanning interval and window parameters until you are happy. If not then you have more choices below. 
 Wait until (if?) Nordic implement scanning on single channel in their SD. 
 Use other BLE stack on nRF5x which supports it (I don't know any such stack but there might be some company having this and willing to license/sell it to you). 
 Use open-source stack such as Zephyr and write the feature yourself (if not present). 
 Write your own stack.
