Herelink 1.0 - sticks not responding

I Have HERELINK 1.0 which worked good for a while (not used alot, but worked well).
Few days ago, sticks stopped responding… even in HERELINK Calibration.
i tried to reinstall firmware (used PC to installed Clean firmware - and upgraded to the latest verion).

now herelink is not paired with airunit - but when i enter to herelink settings to do calibration i dont see sticks moving…

any idea ?

I would say pair the airunit and then test.
