BLE advertising channel

Closed this issue 6 years ago · 5 comments

I would like to know how to see in which channel (37,38,39) the BLE device is advertising its data by using libblepp?.

I don't believe that information is in the scan packet, so I don't have a way of reporting it. I might be wrong though, but none of the HCI dumping tools (hcidump and btmon) show it either.

Thanks for your answer, Dear Edward Rosten could you please tell how can I get that? I have RSSI values, local name, Mac address, scan time, etc. that I can get from the scan packet but still can not find any info about channels,

I don't think the HCI sends that information so as far as I know there's no way to get it.

I don't believe this is fixable. Please reopen if I'm wrong!
