For example, IMEI 356307042441013 would be sent as 000F333536333037303432343431303133. First two bytes denote IMEI length. In this case 0x000F means, that IMEI is 15 bytes long.

After receiving IMEI, server should determine if it would accept data from this module. If yes, server will reply to module 01, if not - 00. Note that confirmation should be sent as binary packet. I.e. 1 byte 0x01 or 0x00. Then module starts to send first AVL data packet. After server receives packet and parses it, server must report to module number of data received as integer (four bytes). If sent data number and reported by server doesn’t match module resends sent data.

#First, the Teltonika device opens the GPRS session and sends AVL data to the server (refer to device protocols).

#Once all records are sent and the correct sent data array acknowledgment is received by the device then GPRS commands in Hex can be sent to the device.
#Once all records are sent and the correct sent data array acknowledgment is received by the device then GPRS commands in Hex can be sent to the device.
#The ACK (acknowledgment of IMEI from server) is a one-byte constant 0x01. The acknowledgment of each data array sent from the device is four bytes integer – a number of received records.
