Hi,
I observed a strange issue using fwupgrade tool. When I’m trying to change Tobii Rex firmware from TCP to HID with parameter tet-tcp://172.28.195.1 then whole upgrade process goes properly (finishes with success). On the other hand when I’m trying to switch firmware from HID to TCP with tet-usb://serial_number as a parameter I get as result: Connect error.
However, when I’m trying to change firmware from HID to TCP with parameter tet-usb://M14K090101 then upgrade finishes with a success. I’m wondering why I have to use such a strange value instead of serial number. Is it hardcoded or something like that?
