|Knowledge about programming language is a must. Teltonika Telematics is a hardware production company, we do not provide software programming services and cannot help with writing code for the server. Only consult on the logic and algorithms of device features and possible issues in data interpretation from the server side.

|Socket Programming
 
−
|Sockets and the socket API are used to send messages across a network. For Teltonika devices to make connection to your server, the server needs to have an application socket programmed to accept these connection request.

'''Note:'''
 
−
 
−
Each socket should be dedicated to one device, this will allow the server to differentiate the devices when more than 1 device is sending data at the same time.

|Cloud storage supports storing cold data on a public cloud object storage service,such as Amazon S3. When using a public cloud, the connection is over a WAN.

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.
