Using the following:
Rigado BMD-360 nRF52811 development board.
Softdevice S140 7.0.1
SDK 16.0
Using two development boards inches apart, one development board sends a single advertising event every 12 seconds. The other development board is continuously scanning (interval and window = 7s). The packets have 30 bytes of data including a sequence number. I calculated packet loss based on the missing sequence numbers.
Sending and scanning using the 1 MB/s PHY, in a test of approx. 20 minutes I get 100% reception of packets.
Sending and scanning using the Coded PHY, in the same test I get ~43% reception of packets, ~57% packet loss.
Is this expected behavior, or could I be configuring something wrong when advertising using Coded PHY?
Another behavior I've seen is for the above condition using the Coded PHY to have a repeating pattern of receiving 3 and missing 2.
