PXX protocol

Wondering what changes were made, now I'm able to bind with my dsm/dsmx models. Tried again with the previous 15oct file just to confirm and didn't bind.

Ahh no wonder, thought u did some magic programming stuff and solved the dsm bind problem

HI !!!
Currently setting a R9 to my T8SG V2 plus, I already done the internal wiring mode but can't find any info on the 3.5mm plug wiring I need to do ?
Blank plug or do I need to wired some pins ?
Thanks in advance.

Hi,

Blank 3.5mm plug seem to work fine, but the range s*cks... With the lastet nightly build rssi drop to 50 at 500m... I have better results with my spi RX on AFHDS 2A protocol...
Look like the module don't output the max power, any way to change that ? test build aren't available anymore apparently

I did validate the deviation power settings in PXX protocol menu on my R9 and it worked, I could change the power levels.

Otherwise try new antenna on the Rx first IPEX miniature connector is very prone to failure.....

Power setting work, but range isn't great on max (auto/200) mode and same range in 500/500 mode.
Everything is brand new, with 868 super 8 on the module and 868 immortal T on the R9mm.

I admit I also not like range of R9 so much, but it has nothing to do with deviation implementation. (same range as when open tx)

off topic:
If using if F-port, monitoring RSSI channel in betaflight, it drops quite quick from 99% to in the 60's. Than drop more slow, but it is quite unpredictable can suddenly move down, also the RSSI changes, are to slow is have few seconds latency, making unpredictable?
But you keep control until 2%, however below 40% I am scared as it behaves not very stable for myself.... (compared to f.i. flysky RSSI, it is very nice smooth predictable with the range) I would use it indeed in similar range as 2.4ghz.... (certainly not trust for long range)

Possibly R9 system may be affected by strong out of band nearby RF signal f.i. from video link? (even 5.8ghz, if antenna re too close?)
In my case antennas are close, it would be interesting test (range without vtx powered).

I see many R9 video where the rssi didn't drop as fast as mine... They advertise 10km range, I already affraid going farther than 1...Should make a test with PPM but I don't know how to set it this way...
Totaly agreed with flysky rssi who's more predictable, and yes I'm on F-port too...
Not sure for RFI, I tested it by walking with it in my hand and I set low power disarm on this quad.

Hi!
Could you help me?
I will use PXX with Devo7e.
I live in Europe and I used my R9M 868 flexfw in a taranis. Witch mode can I set on PXX tab?
My another question,can I use telemetry on my radio? If yes why? I flashed the last nightly to 7e.
Thanks.

Hello, I'm having some issue with R9M+Jumper T8SG PLUS v2:
radio fw: t8sg_v2_plus_v5.0.0-ac7f63e
r9m: RED MODEL NOT2019 fw TX_FLEX_20190117
r9mm: R9MM_FLEX FLEX_Fport
with PXX protocol:
tx power 10/25 mW
country EU
rx PWM out 1-8
rx telem: off
fixed id: 3
#channels: 12

I can bind the tramitter with the receiver but after power-on the radio the trasmitter+drone I need to wait about 1-2 minutes to have connection and RSSI is good, randomly I got strange beavior dron fall lose of connection. min RSSI in end of flight OSD seems to be good.
same behavior in ppm mode.

Thank you for support.

Have a nice day

I have succesfull flights with R9M pxx protocol flex firmware T8SG V2+. Even the power settings and auto power worked. No problems for me.

I would check antennas first. It is very important you flash the receiver and the Tx module to the latest Flex firmware, not use different combinations as there are reports of crashes etc.

So is the Jumper T8SG v2 working with the R9M 2019 version or just the old non 2019 version?

I may try to update again my T8+ fw (latest nightly build). so I can check R9M module

@fernandez

jr bay pins top and bottom need to be connected, right? (just for confirmation)

thanks

Interested to see how you make out as I have an R9 2019 version on the way for my T8SG V2 Plus.

As for the mod you need to make, here's what's stated.

The T8SG V2 Plus requires a hardware modification to receive telemetry from a module in the JR bay. The trainer port ring must be connected to the bottom JR pin (see picture).

hi guys.

have flashed mine to latest nightly version. T8SGv2+ 48d7be1 for the PXX to work well. R9M

im using 4 wire connection for my R9 mini(flex fw) sbus(uart2)/smartport(uart4) on the ports.

FC is matek F405STD.

telemetry set to OFF(radio)

Ive checked all the RF power outputs to be properly working.

today ive hooked quad to inav and monitor the 'receiver' tab.. and on radio, I entered range test mode.

pls check the channel bars, I can see a sudden drop(maybe 5mS) . then resumes again. is this NORMAL?

im afraid that when I go really Far that it would behave this way..when rssi falls too low.

Jumper T8SG v2 plus is working with R9M and have telemetry working as well. Only problem I'm having is with failsafe return to home. I can return to home via a switch but if I turn off the T8SG V2, the quad just drops. Anyone have any ideas or have this feature working with the same setup? Running iNav 2.5.

I think you have to set up the failsave instruction, inside the flight controller not in deviation.

I have it all set up in iNav correctly I believe.

Not sure if this will help but here goes, NurkFPV did a video of his BF quad with crossfire. He finally got his return to home "loss of radio" working by changing the failsafe on the module from "pause" to "cut". Like I said i dont know anything about R9 or iNav but thought this might help.....
