I purchased several GT06 type devices from alibaba. I used to buy from the same seller, same devices, and have successfully used the GT06 protocol. I have a problem with the new ones - I send all the settings, but my traccar server does not received any data from the devices. When I point a device to the Chinese platform, the data appears there. The manufacturer sent me a file describing the protocol, can anyone look at it and help?
The pdf file with protocol details can be view here - https://files.fm/down.php?cf&i=tvqsb56z&n=78f83775a1a663a0abc52154006e725b.pdf
It's H02 protocol.
