Got a herelink unit with a strange link problem.
If both remote and air end are inside a room/building, the link between them is steady , streams video etc and overall seems to work fine.
If I take both air and remote units outside, within a few seconds the link data rate drops out from ~60kbs to 1kbs and then the units disconnect entirely. Restarting the units does not help.
Updated firmware to 0.22 on both remote and ground end. Tried powering air unit at 5 and 8v via fixed switching BEC or adjustable BEC.
Tried rebinding, tried auto/manual freq. mode, tried reducing/increasing bandwidth for upload/download, tried 3 different outside locations and 2 rooms, different antenna placing on a quad(nothing else transmits from that quad, not even 2.4g radio receiver).
See a video here:
I’d say faulty hardware but I cant explain either why indoors the link is solid and never drops out in 5-10 minutes of test, while outside out of 1 minute 50 secs is disconnected.
