Scan on a single channel functionality

[Kristoffer Hilmersson]

Hi!

Is it possible to scan on a single channel using SoftDevice 132 running on nRF52? If no such functionality exists, is there some workaround? Like timeslot API for nRF52.

Thank you!

Hi, Kristoffer!

Before going in this direction (scanning on a single channel) you should consider that advertising/scanning is set up the way it is to provide a more robust system. By using three advertising channels and cycling between these, you are more likely to achieve contact between your advertiser and your scanner. If using only one channel, you basically have only one bet. If that channel is blocked or noisy due to some interferer, your packets may not go through. By using three channels spread out through the frequency range the risk of being blocked is much reduced.
