Taranis Q X7 International FW connecting XSR-SIM EU LBT or FCC ?

Post by Robotix » Mon Jun 03, 2019 10:44 am

Not sure if this is more an openTx or FrSky issue but here goes.
I have a Hitec Rovonova RB-01 robot with a board running Lubuntu linux and needed a reliable control method, something tactical, so using a Taranis Q X7 I have for drone stuff, I ordered a XSR-SIM USB adapter from Hobbyking, they only sell the EU version. https://hobbyking.com/en_us/xsr-sim-eu-version.html

So according to the quote below, I am running a Taranis Q X7 with International firmware *see quote below

FrSky only provide firmware for the XSR-SIM as either EU or FCC versions... is one more likely to work than the other with an international Firmwared TX https://www.frsky-rc.com/xsr-sim/

I can't seem to get them to bind, so my question is. With international version on the TX, is it going to work if I flash it with the FCC version or am I am better to adapt the TX to be either FCC or EU ?

Also looking for the next steps of ways to interface C++ apps running on linux to the USB-SIM device, any suggestions on libs they use for the sims would be amazing.

I am in Australia. Cheers for any insight. :D
HOW TO KNOW WHAT FIRMWARE YOUR RUNNING
Go to model setup in your taranis, under "Internal RF", "Mode" and see how many different options you have.
D8, D16, LR12 - if you can select all three then you have the international firmware
D16 only - you have one of the first versions of the EU-LBT firmware. If this is the case you really should update your firmware because it's quite outdated
D16, LR12 - you have the newer EU-LBT firmware, and you can use the radio for both the X-series and L-series receivers (but not the D series)
(These options are TX to RX protocols as explained here: https://oscarliang.com/pwm-ppm-sbus-dsm2...ifference/)

You can flash the xsr-sim with international firmware.

It appears as a standard joystick so any lib for that should work.

Note that you might need to plug it in your board after it has booted.

Yeah good point about the jstick lib, it’s a little limited to lubuntu 10.x due to dropping support for the x86 after that. Board is ROBOARD RB-100
