Herelink pair issue with Airlink Negotiation timed out , please try again error

Edited 18/09/2023


For some reason, the Herelink remote unit stopped transmit mavlink messages from QGC with a disconnection message display. After a review, i understood , while pairing with Airunit , the herelink shows the message " Negotiation timed out , please try again" . I have gone through the web link

but yet it simply doesn’t pair together.

Could someone shed some light here .

thank you

OK . So this was solved by restarting the airlink unit after the firmware was reloaded using the above link . Then the mavlink starts to communicate thro’ Herelink -----> herelink settings !!
