Question about the scanning channel(s) #405

Open ececli opened 4 years ago

ececli commented 4 years ago

Hi, I want to ask a quick question here. When running the Scanner.sccan(Timeout), will the device scan all 3 advertising channels in the duration Timeout, or it only scans one channel? If it scans 3 channels, does it scan each channel using Timeout/3?

Thank you!

Chang

Hello! I am also interested in this question, did you find out the answer? Also, do you know if it's possible to get the channel on which a beacon was received? Thanks!

Hi lauraflu,

I didn't get the answer from this site. But I do find a way to get the channel information in my project (You can view it on my GitHub). Basically, when the transmitter sends a signal, it sends on a particular channel. And I add the channel number information in the signal. The receiver can decode the signal and then knows the channel.

Hi ececli, thank you for your answer. This seems to be the best method, as from some searches I saw that there's basically no way to get the channel the message was received on (so on the receiver side) from the driver.

Hi, ececli and lauraflu. I am also dealing with the same issue. Is there a way to a scan only one channel (37 for example)? I am asking this because I could not able to modify the channel of my BLE Advertising device (which is HM10).
