I’m currently using Arduplane 4.0.8 on a Cube Black and had previously had RxRSSI working on the HUD (not sure which versions of Arduplane or Mission Planner unfortunately).
RxRSSI is logged correctly in the data flash logs.
Lately it has not been working, and I note that the fields in the status tab are not working either, nor are they in quick view if you enable them. The same issues also seem to affect chXin and chXout.
I noticed that SR1_RC_CHAN is set to zero. (Modem is on Telem 1 which I believe to be affected by SR1_xxx?) I tried setting this to 2 as I thought that it might fix the issue. However, this reverts to zero on reboot. I gather from other posts that this may be changed by Mission Planner? I’m also not sure whether it is the cause of the issue.
I have tried Mission Planner 1.3.75 and 1.3.76, with the same behaviour.
I really need to have RxRSSI displayed for safety monitoring reasons.
