SMS Data Sending

These settings allow sending AVL data using binary SMS. AVL data will be sent by SMS only when there is no GPRS connection. This setting does not affect replies to SMS request messages – answers are always sent back to the sender's telephone number.

SMS commands

Essential fields in SMS/Call settings are Login and Password. The login and password are used with every SMS sent to GH5200. If login and password are not set, in every SMS sent to GH5200 device two spaces before command have to be used (<space><space><command>).
Command structure with set login and password:
<login><space><password><space><command>, for example: "asd 123 getgps"
Phone numbers have to be written in international standard, using "+" is optional but not necessary (in both cases number will be recognized, but when number is without "+" symbol, IDD Prefix will not be generated, which depends on location of the phone). If no numbers are entered, configuration and sending commands over SMS are allowed from all GSM numbers.

Bw nb.png SMS login and password and authorized numbers list are used to protect GH5200 module from unauthorized access. Module accepts messages only from a list of authorized numbers and with proper module login and password. Phone numbers have to be written in international standard using "+" or without using it (in both cases the number will be recognized). If no authorized numbers are entered, module accepts messages from all numbers.
