My issue was the TX pin wasn't inserted properly. After disassembling TX I tried to put crossfire micro module socket into the pin directly and the ring started illuminating.

Another issue is I can't enter crsf menu with nightly build 9fd50b5. Let me know crsf menu supported nightly build?

Glad you got it sorted. The CRSF configuration feature is not yet in the nightly builds. The test build here is up-to-date with the nightly builds.

Really appreciate your help and contribution on crsf support!!
Without your effort we can't use crsf in deviation with t8sg.

There's no changes to CRSF in the test build link above. It just updates the test build with other recent changes in the nightly build.

Hey :)
Any one has info if we can run Crossfire on Devo 8s (ready to cut plastic and make it fit), but ppm out is not an option - delay is to much after conventional 2.4ghz racing.... Otherwise any solution on long rage TX/RX with SBUS and RSSI for Devo?

On the devo transmitters the CRSF signal appears on the TX pin (tip) of the trainer port. Connect that to the module CRSF input, and connect grounds together. The CRSF input on the TBS module is the bottom JR pin - not sure where that connects on the TBS itself.

Hi skullq, can I ask You a support regarding Jumper T8SG V2 Plus? I have probably the same revision You have, with voice support already embedded (the PCB is T8SG-V3-PLUS). I updated FW and file system, but didn't make a backup of "hardware.ini" file. So I lost voice support. Can You, please, provide me with Your "stock" hardware.ini config file? Thank You a lot in advance for this.

Great thanks! Still desiding which one would work better on 8s TX - CRSF or new R9M Light Pro TX, 1w now, + Nano RX with over the air update :-D

is R9M Light Pro connection possible ? Which one is better integrated R9M or Crossfire in your opinion?

Looks like fully supporting the Light Pro requires adding PXX2 protocol. Won't be able to look at that till next month. Last I asked Frsky wouldn't share the PXX specification so it'll have to be deciphered from opentx or ersky.

The crsf_configuration test build supports configuring the Crossfire tx and rx through deviation.

I go the T8SG plus 2 carbon and I did the hardware modification and it works well with crossfire (crsf v2) (stock firmware)

@hexft: Should I upgrade the radio with the crsf firmware that you did ? What are the benefits right now ?

The crsf_configuration test build supports configuring the TBS devices by clicking on the protocol name. The control and telemetry code is the same as the nightly build.

The nightly builds (under Downloads on the left) have CRSF support for control and telemetry.
The crsf_configuration test build adds support for configuring the Crossfire devices through deviation.

I have the same issue as skullq. I Think the pins of the module connector to short. When I remove the back cover and put the crossfire on the pins the LED illuminate but with the cover nothing happens.

a little youtube Video it shows the issue


Skullq how do you solve it?

My issue was mostly same but pin length was not short. PIN just didn't properly aligne between TX and crossfire module.
Try to align crossfire module on left or right bay while you inserting the module. you may understand my point. lol

Hi Skullq, thank you very much!
I screwed the Micro tx apart, put the lower part into the jumper, put the board on the pins, switched it on and the LED shone. :) I screwed the board back on and mounted the lid. Now it works and I will never get the module out again. ;)

Hi,
I've just bought Crossfire Micro TX and im unable to configure it on T8SG v2 Plus
I did hardware mod with removing firs pin and connecting it to last pin.
Crossfire module is blinking yellow and nothing is happening when i press enter on CRSF in model setup.
I'm on latest firmware, t8sg_v2_plus-v5.0.0-abcac7f.

What i'm missing?
