Codec 15 is based on Codec12 protocol. Codec15 is original Teltonika protocol for device->server communication over GPRS messages.
Codec 15 relies on the Codec12 protocol and is employed when both message timestamp and device IMEI are enabled. It serves as the original Teltonika protocol for communication from the device to the server via GPRS messages. This protocol is exclusively applicable to FMX6 professional devices.
Codec15 is available in RS232 modes:

CRC: 0x 000093d6
The algorithm to calculate CRC is CRC-16 (also known as CRC-16-IBM). All the fields from codec ID to second command/response quantity field are used to calculate CRC.
