Dear Dialog,

I'd like to know following points about DA14580's central operation mode.

Q1: We observed that rssi seems to have strong dependancy to the scanning channel. When we set 5seconds
for scan interval, we saw 5 seconds'periodic change of rssi by almost 10 - 15dBm change even the distance
of central and peripheral is fixed and experiment is conducted in the shield room.
Can you explain this phenomenon?
We have checked there is only a very slight varience like 1dBm for peripheral's transmit power.

Q2: Is there any method available which allows us to retrieve the channel number information by each adv
packet received?

Q3: Can we make DA14580 scan by only one channel? I mean no frequency hopping between ch.37, 38 and 39.

Best Regards,

Device:
