Set up Route for Data Transmission
This SMS command instructs the device decide to transmit GPS (GPRMC) positioning data to where in which protocol.
Please confirm the back-end server protocol type and corresponded URL or IP address (with port number if required)
before setup. There are 4 main protocols available for transmitting route setup:
1. HTTP: Hypertext Transfer Protocol. An internet browser based server protocol that usually has a specified URL (Uniform
Resource Locator).
2. TCP/IP: Transmission Control Protocol. An OSI Transport layer protocol that has more complex frame structure, higher
reliability but slower processing speed than UDP/IP.
3. UDP/IP: User Datagram Protocol. An OSI Transport layer protocol that has faster processing than TCP/IP but does not
guarantee data delivery.
4. SMS: The DEVICE will send GPS data by SMS message format to Cellular phone.
User can choose the route to transmit the data by HTTP/TCP/UDP protocol individually or with SMS message as a backup
route. Please refer to the following table for the route setup.
