LOOP1 has transmitter signal quality in it.
At least, I run LOOP1 and have signal quality.
No sorry it doesn't - wireless quality is not in the LOOP packets. (Though there is a measure of wireless quality in the
archive packets and this is presumably what your software is monitoring.)
There are essentially two measures of 'transmitter signal quality' - the % packets received error-free in an interval or time period and the RSSI of the latest packet. I agree that it would have been good for the RSSI to have been included in the LOOP but it isn't. The % good packets received would be difficult to include in a LOOP (except perhaps as a running average or overall % since midnight) because - roughly speaking, since they are two separate processes - one LOOP includes only the latest wind packet data and hence it would be difficult to calculate current reception % from a single value.
So, as far as I'm aware, the only measure of wireless quality passed to software is in the archive packets and not the LOOPs.
