Ok, i want to get CRSF working, i have latest nightly build 69a18e2.

What more do i need to do to get CRSF Configuration working (preferebly with 3.24 CRSF firmware CRSFShot)

If there is a hardware mod needed, just draw it or take a pic of the back pins and doodle it.

Help us out here.

PS. My CRSF micro shines out of the box.

Hi there, new user, considering getting the new JumperTX TS8G.

Just want to clarify regarding binding support on CRSF.

I have read elsewhere that in order to bind to a receiver you require an OpenTX radio. Is this still true or is this now supported in deviation?

I'm asking in this thread as it seems to be the most recent on the topic.

TIA

Hi, you can bind also with the Jumper T8SG V2+ and deviation software.

Is the hardware mod required on a new (3/2020) T8sg Carbon?

Hi everyone,
I've recently installed my first Crossfire nano diversity receiver in a Quad. I'm using a Jumper T8SGV2 Plus running firmware t8sg_v2_plus-v5.0.0-2bf5e52. This one of the firmware versions listed in this thread. I'm using the Crossfire Micro TX and the TX/RX are running current Crossfire firmware. I performed the hardware mod in the T8SG, the CRSF menu works and I can configure the Crossfire Micro TX, the RX is bound. Happy days.

I notice that the GPS co-ordinate telemetry data is incorrect as displayed on the Jumper T8SGV2 plus.

The Quad is running BF4.1.7, and has a small GPS receiver on board. It reports the correct location to Betaflight Configurator and sends the correct GPS coordinates to the OSD. The problem is that on the Jumper radio, GPS telemetry is reporting the incorrect coordinates. I am located on east coast of Australia (lattitude -27, longitude 153), and the location reported is in Ethopia. The speed and altitude telemetry data seem to be correct.

Pictures of Betaflight and the radio are attached for comparison

I'm not sure that the problem is with the radio firmware, but I'm wondering if anyone might have a suggestion on how to have the correct GPS location telemetry data displayed? Thanks in advance

Hi, have you found out if the mod is required on the new t8sg carbon? What nightbuild is the right one for the carbon edition? Thanks.

I am working to determine if the Jumper T8SG v2 Plus Carbon (board marked v3) actually needs the mod. Upon first inspection my feeling is yes.

The good news is it appears that Jumper may have done us a favor and added solder pads that can be bridged to connect the pins as with the previous mod for Yellow V2 plus.

I will take some video and get it up later but am still confirming what I can with the multimeter.

I also find that the micro module doesn't seat well in the case. Perhaps someone can speak to this issue.

Yes, you need to fiddle a bit with the module until you manage to get it in the case. Once it is in and you turn on the TX the module will light up. The thing is that when you select the CRSF protocol nothing happens there is no menus or any other options. I guess that we need to update the firmware but I am concerned about doing it because this is a new jumper t8sg v3 plus and I am not sure if the firmware will be compatible. I don't have much experience upgrading the firmware and I would not like to brick my TX.

I managed to bind the crossfire module to the xf nano receiver with the module connected to the jumper t8sg carbon edition. And I also managed to get it working but using the PPM protocol instead of CRSF. I haven't been able to go out and fly yet but in betaflight all seems to be working fine, sticks, modes... I don't know how but the jumper and the crossfire module appear to be communicating to each other. I just plugged in the module, bound it to the receiver and selected the PPM protocol. I didn't even have to bridge the pins in the jumper.
