Question

Hello,

My tracker FMB120 is sending the same records ( 16 records ) continuously for movement events (low priority).  Hower, the events with high priority ( ignition ) are sent immediately to the server and work perfectely.

I checked the ACK : the server send  to  the module the value :  0x00000010 = 16 records.

Could you please help me to undertand this behaviour ?

Other Informations   :

codec  : 8

Number of Records 1 : 16

Number of Records 2 : 16

The static navigation filter is enabled

Best regards

Hello adgeo,

Thank you for question and information.

Could you please say do you get the same AVL data packets?

Also, please check if your Min Saved Records value is 16 in Teltonika Configurator --> Data Acquisition. If yes, that might be the reason why you get 16 records.

We are looking your answer.

Best wishes,

Teltonika Support

Hi,

Yes, the same AVL data packets are sent to the sever even if they are already saved and acknowledged.

After cheking,  Min Saved Records is equal to 1 (see config below )

make sure to report module number of data received as integer (four bytes).

If sent data number and reported by server doesn’t match module resends sent data.

nodeJS Code:

const buf = Buffer.alloc(4);

buf.writeUInt32BE(recordsCount, 0);

socket.write(buf); //send to device to confirm sending
