Hi,

i'm trying to create tcp server for fmb204 with PHP. I'm able to receive data (codec 8) from fmb and parse it, but i receive always same data (16 record) . I respond to fmb with record number (i try in decimal format, hex and bin).

Can someone help me?

Thanks in advance.

Hello

When replying with the record number to the device, respond schould be always 4 bytes HEX:

For example is number of data is 02, server schould reply: 00000002

Same problem here

I try this php api https://github.com/lbarrous/TeltonikaPHPDecoder and this c# api https://github.com/SpaceQuantum/GPS-Listener-Parser.

Always receive same 35 packets. When receive data, Api sends count of packets(35) in four bytes format. Sometimes receive new data but then it repeats itself again.

If format data from gps and if the count data is less than 35, gps sync data correctly. If the gps loses the signal gprs and stores more than 35 records, it will fail again.

Hello.

Your server response to this packet schould be 00000023 (35 dec).

You could test communication using Hercules and observing records sent counter (Status->GSM Info->Records) in the configurator.

Hercules usage is described on our Wiki:
