A codec is a device or computer program for encoding or decoding a digital data stream or signal. Codec is a portmanteau of coder – decoder. A codec encodes a data stream or a signal for transmission and storage, possibly in encrypted form, and the decoder function reverses the encoding for playback or editing.

Below you will see a table of all Codec types with ID’s:

Also, there are using two data transport protocols: TCP and UDP. But it is not important which one will be use in Codec.

*'''<big>Protocol Overview</big>'''

Codec8 – a main FM device protocol that is used for sending data to server.

*'''<big>Codec8 protocol sending over TCP</big>'''

TCP is a connection-oriented protocol that is using for communication between devices. How this type protocol works you will read later.

'''Preamble''' – the packet starts with four zero bytes.

'''Data Field Length''' – size is calculated starting from Codec ID to Number of Data 2.

Line 60: Line 65:

'''Number of Data 2''' – a number which defines how many records is in the packet. This number must be the same as “Number of Data 1”.

'''CRC-16''' – calculated from Codec ID to the Second Number of Data. CRC (Cyclic Redundancy Check) is an error-detecting code using for detect accidental changes to RAW data. For calculation we are using CRC-16/IBM. More information about it you can found [[Codec#CRC-16|here]].

'''Note:''' for FMB6XY and FM63XY, minimum AVL packet size is 45 bytes (all IO elements disabled). Maximum AVL packet size is 255 bytes. For other devices, minimum AVL packet size is 45 bytes (all IO elements disabled). Maximum AVL packet size is 1280 bytes.

*'''Communication with server'''

+

First, when module connects to server, module sends its IMEI. First comes short identifying number of bytes written and then goes IMEI as text (bytes).

For example, IMEI 356307042441013 would be sent as 000F333536333037303432343431303133.

Line 230: Line 242:

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.

+

*Example:

+

Module connects to server and sends IMEI:

000F333536333037303432343431303133

AVL data packet is the same as with Codec8, except Codec ID is changed to 0x8E.

*'''Communication with server'''

Module sends UDP channel packet with encapsulated AVL data packet. Server sends UDP channel packet with encapsulated response module validates AVL Packet ID and Number of accepted AVL elements. If server response with valid AVL Packet ID is not received within configured timeout, module can retry sending.

AVL data packet is the same as with Codec8, except Codec ID is changed to 0x10.

*'''Communication with server'''

Module sends UDP channel packet with encapsulated AVL data packet. Server sends UDP channel packet with encapsulated response module validates AVL Packet ID and Number of accepted AVL elements. If server response with valid AVL Packet ID is not received within configured timeout, module can retry sending.

*'''<big>About Codec12</big>'''

+

Codec12 is original and main Teltonika protocol for device-server communication over GPRS messages. Codec12 GPRS commands can be used for sending configuration, debug, digital outputs control commands or other (special purpose command on special firmware versions). This protocol is also necessary for using FMB630/FM6300/FM5300/FM5500/FM4200 features like: Garmin, LCD communication, COM TCP Link Mode.

*'''<big>GPRS command session</big>'''

Following figure shows how GRPS command session is started over TCP.

The GSM/GPRS commands can be sent from a terminal program. We recommend to use Hercules (in TCP server mode). Simply write command as explained below into Hercules Send field, check HEX box and click Send button. Note that the TCP server must be listening on specified port (see Port field and Listen button below).

*'''<big>Decoding GPS position</big>'''

+

When decoding GPS data with DifferentialCoords = 1, Latitude and Longitude values can be computed as follows: Longitude = prevLongitude – LongitudeDiff + 213 – 1, Latitude = prevLatitude – LatitudeDiff + 213 – 1.

If there were no previous non-differential positions, differential coordinates should be computed assuming prevLongitude = prevLatitude = 0.

AVL data or events can be sent encapsulated in binary SMS. TP-DCS field of these SMS should indicate that message contains 8-bit data (for example: TP-DCS can be 0x04).
