I must be having a complete brain fart episode - i have completely lost any memory on how to setup RSSI on the R-XSR - frsky via sbus connection method.
I have 2 basic telemetry channels coming to X9+ radio - i see RSSI to show up, so, somehow it is getting sent from R-XSR to the radio. LUA script can show it, if I map it.
in the MP screen there are 2 live params - ‘rssi’ and ‘remrssi’ - both always remain at 0.
OSD item for RSSI also remains at 0.
looking at RSSI_ section of params i hav a feel it got erased somehow - as RSSI_CHANNEL is set to 0 and RSSI_TYPE is set to 2.
do i understand correctly that a proper value for RSSI_Type should be ‘3’ - receiver protocol? i tried to set it to 3 - but rssi values remain as 0 while radio shows 96-87dB values.
The way I have done it (but you might be talking about a different method) is by selecting mode 2 for the rssi type.
Then on the transmitter I go to the channel map and select a channel and set its source as “RSSI”.
Then in the ardu config, type is two, and I tell it which channel I told it to transmit RSSI.
hmm. may be. i think it would work.
i am just confused - i for some reason assumed, or presumed, that rssi can be sent somehow directly via sbus output from r-xsr into the copter code and it was supposed to work ‘as is’ via frsky protocol.
ok, i will try to set it via channel way, it will eat up one channel but it is ok. i must have mixed up something.
i just erased and recreated all models playing with radio, so probably just erased all this setup that was done years ago and forgot all about it
ok. got it working - but, in MP ‘rssi’ value still shows as 0. in OSD it shows percentage now, i set it on channel 15. with max value - close to the model, i see rssi value to come as ‘1544’. do you know what will be the lowest value for it? i cannot see at home what it should be set to - it does not deviate much.
I have mine set at 1000 for low, and 2000 for high.
I believe it uses the full standard PPM range.
For RSSI in the HUD, the basic RSSI it shows automatically is telemetry RSSI.
So, I add RCRSSI, and that works for me, to display the RC transmitter RSSI.
Here are my copter settings:
RSSI_ANA_PIN,0
RSSI_CHAN_HIGH,2000
RSSI_CHAN_LOW,1000
RSSI_CHANNEL,12
RSSI_PIN_HIGH,5
RSSI_PIN_LOW,0
RSSI_TYPE,2
so, before i set that like you did - only used channel 15 instead of 12 - in the OSD item OSD2_RSSI_EN - it was always showing 0.
i assumed that if now it started giving 1544 for the max rssi - the value of RSSI_CHAN_HIGH had to be adjusted? as how else it would know what a 100% stands for?
not sure, i can try to experiment more, it looks like i may be missing the concept here.
on the taranis i added it in the input window, as a new imput using a source ‘RSSI’ - there was also a ‘RSSI-’ and ‘RSSI+’ - i used ‘RSSI’. then this new input was given to a channel 15 as a source. and with closest proximity it sends in ‘1546’-‘1544’. something. if radio is moved into a diff room, it drops a bit, to a ‘1534’ something. that is why i presumed i need to set max and min now?
if yours sends in ‘2000’ for a full strength rssi - i am not sure where is it set?
