Is there any Manul or automatic GPS protocol identification system?

Hello,
Is there any GPS protocol identification tools or manually identify the GPS protocol guideline at Flespi?
There are a lot of China branded devices which are ignored at Flespi and not yet added .

As I check their protocols, protocol documentation is like 1 page or 2 page and they are using similar Chinese protocols but different GPS companies.

I also heard Flespi is developing a system that user can add the protocol by themselves. Hope it finish soon .

theinhtite the only way possible is to capture raw traffic from the device and analyze it. You can do it via proxy channel.
If you need some automation, you can write a script that runs over each protocol and:

creates channel of specified protocol
sends captured traffic sample to created channel uri
checks for parsing error or parsed messages
deletes channel
goes to next protocol
Yes, we plan to release the technology to write your own parsing code. But no time estimation yet.

baja Thanks for the suggestions, but in reality it is time consuming. May be you have like this , https://www.traccar.org/identify-protocol/ . So customers can able to identify any device protocol by looking proxy channel and sample device hex messages.
Regarding china devices, those devices have price advantage and should added to flepsi, China devices use same one or two based protocol.
