XJT module firmware

Simo1980

Hey guys and girls, sorry if this is a silly question, im very inexperienced in the world of RC.
Is there a way of checking the firmware version on my frSKY external XJT module plugged in to a turnugy 9xr (not pro)?

Thanks for your time.

Not as far as I am aware. What are you wishing to do, as the old addage goes - "if it works ... leave it alone".

Thank you for your reply, im looking to purchase a frsky x4r-sb receiver, I purchased my radio and module early 2015 when the new EU LBT firmware was released so im not sure if i have the old eu or new eu firmware on the module.

That will be the old EU LBT. The later version was not released until 2017.
