As you know, channel info may display in sniffer packet windows.

Hi,

We do not pass up the channel info up to the application level from the stack lib, just the RSSI.

Thanks,

thanks to Zahid Haq，
We found RSSI vlaue unstable when use pEvent->deviceInfo.rssi. then we capture advertising packet by sniffer,it's stable by ±1dbm at channel 37.But RSSI value is large difference when two dongle is used.one is capture at channel 37,anther is at channel 38. The stable value is very useful for BT location.
