Hi everyone, hi Snowleopard,

lately I'm getting a lot of RSSI dropouts. The problem started a few days ago, but as far as I recollect I didn't change much, only the output power of my Nano TX which I also reverted afterwards.

The problem does not seem to be related to the range the quad is from the sender.

I replaced the crossfire antenna, without success.

Here is some data to make the problem clearer:



I walked like 3 meters to test this.
(cyan) LQ min: 98
(red) RSSI min: 0

I've read here that high LQ with low RSSI in a short range, is most likely an antenna problem, since I replaced it, I don't know how to proceed debugging this.

Thank you for any idea on how I could tackle this issue, before soldering a new nano tx.


Additional information:
* The signal is right back up, I only hat 1 failsafe event that past few days, but I lost a lot of trust into the connection.
* The logging is only 45 seconds long
* I use a nano RX, Rev 45 on the latest TBS firmware
* I do not have a second drone to test if the receiver or sender is the problem

I replaced the nano rx module now, same results.

for crossfire you like to use "rssi dbm"

I followed which seems to resolve the issue, I'll test it today.
