1) How to set the scan mode to scan only one of the advertisement channel (37,38,39).
2) receiving message at scane mode , how do i know at which channel the data was received, "struct gapm_adv_report_ind" do not have the channel.

Scan specific channel
Hi Tzvika,
Normally all three advertisement channels are scanned in order to prevent that an RF interference causes you to miss an advertising event. Limiting yourself to only one channel will possibly reduce BLE performance and is not commonly used. Therefore this information is not directly available from the scan results. We would have to investigate if there is another way to get this info. Is there a specific reason why you want to use one channel only?
Best regards, RvA
Hi ,
From my investigation I notice that each scan window is scan one specific channel , is it correct?
We need that because each channel has a deferent RSSI and we need to measure the RSSI on a specific channel and compare between them.
so you give me no answer , how I get the channel?
Hi Tzvika,
We checked internally but it is unfortunately not possible to only check individual advertising channels or retrieve the specific advertising channel number. This is too deep embedded in the BT embedded firmware protocol.
Best regards, RvA
Hi,
I am sorry for being impolite, but when the customer asks for a feature, your internal considerations such as "this is too deep in embedded code" doesn't help.
Do your prioritization, and tell us if, when and how this feature will be available.
Please add the option to scan individual channel (or any other combination of channels 37-39) as a feature request.
Most of your competitors have this option.
Hi doman,
As i ve mentioned in your previous posthttps://support.dialog-semiconductor.com/forums/post/dialog-smartbond-bl...the scan command talks directly into the stack which is located in ROM, inserting this feature isn't something that is going to happen in a sub sequent SDK release since that feature dictates an update on the BLE stack, this is something that we are checking but is not going to happen soon and most probably not on the 580 as well.
Thanks MT_dialog
