4g portable device using 7878
Do you have the protocol documentation for your device?
Hi Anton, unfornatelly not, Even I have a aliexpress case open now, because the seller is not helping with the protocol documentation, Im my server Im getting a lot of information of this device, I could get protocol numbers like 13 / 18 / 19. and checking all the files that I have here about gt06 or similar protocols, that use 7878 in the beginning, I could get imei number, status number, lbs information ,but Im thinking that the real gps position is coming from the protocol B3, I will put here some messages from this device:
78780d010359339079971913050d0a --> imei787801570d0a SynchronousSetupData787801300d0a UpdateTime787801990d0a sos alarm787800182308080548540302d403000079bb010049df5d000079bb0111c40965000079bb010049df5d100d0a LBS extended Message Packet787816130005085853010000000000000000001708080d31050d0a Status information packet787815b338393535303331323030303035343635333134330d0a I think this protocol has something interesting, but b3??????
It just has this as the payload:
89550312000054653143
do you get this line 89550312000054653143 from this 787815b338393535303331323030303035343635333134330d0a ?
if yes, do you have the protocol that you get it? this is the gsm card number.
I just ran it through HEX decoder. I don't have the protocol.
how to decode this can you explain about hex decoder
Hi, I have bought this device: https://pt.aliexpress.com/item/1005005237607524.html
Im trying to get data from it using gt06 protocol, but Im getting the following line:
according to documentation that I have from gt06, 7878 its ok, 15 it was supposed to be the lenght, and b3 after that, should be protocol number, but Im not finding any protocol number equal b3, any idea to help? thank you.
