I first received the IMEI number and acknowledged by 0x01. It worked and send back AVL data.

AVL is acknowledged and we send back to device  '16'. But the same data is being send again and again.

Also, since there are more than once record in the packet, after the last data in the first record, does it start with time stamp again for the second record..

Hi

The number of records in the AVL packet is 16  (hexa) which is 22 ( decimal).

I thind you should send  : byte[] { 0, 0, 0, 22 } to the module.

Best regards

I have the exact same problem with a FMB130. I get Number of Data 1 = Number of Data 2 = 16.

I reply with byte[] {0, 0, 0, 16} which is 0x00000010 and the device closes the connection. Then the exact same package is sent again.

Can someone help on this issue?

Answer 1

Hello, touchworldtechnology.

It's not clear what acknowledge message you sends exactly. It should contains four bytes - 0x00000016

Answer 2

Hello,

Try to send as byte array that contains 16 and capacity is 4

new byte [] {0,0,0,16}
