Hi
How can I check the time of lost and quality of RC connection. I know that I have to do it in Mission Planner in “Review a Log” but in Log Browser which function? I have Frsky Horus X10 Express in “Access” with Archer GR6.
regards

I think RSSI is what you are looking for.
You can also check RCDA and RCIN.

To get this RSSI I have to enable RSSI_TYPE:5 ?
