7.1.3.SMS AT Command
SMS AT command means that we can use SMS to query and configure the parameters of G786-G.
SMS AT command is generally used when customers need to query or modify parameters temporarily. We
can query and modify parameters as long as know the phone number of the device, which is very convenient
for equipment management in remote areas.
Take the query of firmware version as an example, send AT command. Send "www.usr.cn#AT+VER" (Note:
there is an Carriage Return at the end of the string) from the mobile phone to the module. After receiving it,
the module will return the response information as shown in the figure below：
7.1.4.Command Format
AT command is "query and reply" command, divided into "query" and "reply" two parts."Query" means that
the device sends an AT command to G786-G, and "reply" means that G786-G sends a reply to the device.
Note: characters in instructions are case-insensitive.
