2.5 Remote Configurations
SMS commands and remote AT commands can be used on ER-600 to
modify configuration parameters remotely. Details are described
below:
1. Modify configuration parameters remotely via SMS
The SMS to configure ER-600 parameters should follow the format
below: SMS password;AT commands
1) SMS password is the "SMS wakeup password" as shown in
wireless network settings of the web configuration interface,
with "1234" by default. This password is used to filter rubbish
SMS. Long SMS is not supported.
2) There can be multiple AT commands, and ";" is used between
SMS and AT command, and between AT commands. If there are
more than one AT command and some command fails, the
following commands will not be executed. If a command is
unknown, an ERROR will return. The commands will take effect
after system reboot. This can be done by putting a command
"AT+REBOOT" in the end of SMS commands, or sending a
separate SMS with command "AT+REBOOT".
3) AT command must be capitalized, but the parameters in the
command do not have this limit.
4) If there are multiple parameters in the command, just write
those that need to change and you do not have to write all of
them. If some item does not need to change, write two
continuous colons, and if some item needs to clean, write a
space. For example:
AT+WN=3gnet (configure onely APN, and other parameters keep
unchanged)
AT+DC=,,user (the first two items keep unchanged, and change
username only)
AT commands that can be used via SMS are listed and described
below:
1) AT+WN=apn,user,passwd,net_mode
Configure parameters related to dialling, with reply OK or ERROR.
apn: Access point name, this parameter is unused for EVDO device
and can be null. write "auto" to ask to select APN automatically.
user: dialling account, the dialing password must be changed
together with dialling account.
passwd: dialling password, the dialing account must be changed
together with dialling password.
