ATI1 <== This is the firmware that is loaded on each of our modems
Cinterion
PLS62-W
REVISION 02.010
A-REVISION 01.000.11
OK
========================================================================
Below is a snippet of code showing EXACLTY how I setup each modem.
Each command is executed “in order” and returns an “OK” before a modem is deployed
string[] modem_config_cmds = {
"ATI1", // Display mode & Firmware
"AT+COPS=2", // Manually unregister from the Network .. Just in case it is already registered
"AT&F", // Restore the factory Default settings
"AT&V", // Show the current configuration
"AT^SCFG=\"Userware/Autostart\",\"\",\"0\"", // Turn off any factory installed program(s) Specifically EZeye AND sometimes the remote access
"AT^SJAM=5", // List running modem applications .. if found, we need to disable them
"ATE0", // Turn off echoing of commands entered
"AT+CMGF=0", // Turn on PDU mode for SMS messages (versus using TEXT mode)
"AT+CNMI=0,0,0,0,1", // SMS UCR event message configuration
"AT+IPR=115200", // Baud rate for serial interface
"AT+CREG=0", // Disable registration messages .. the PLC will poll for them
"AT+COPS=4,0,\"T-Mobile\"", // Try T-Mobile as Network/Operator before looking at other operators
"AT^SXRAT=5,3", // Use LTE and Fall back to GSM if LTE not available
"AT+CMEE=2", // Error message Format .. 2=Verbose strings
"AT+CSMS=0", // Select Message Service .. 0 seems to be the default for USA
"AT+CGSMS=1", // Select service for short messages 1 seems to be the default for USA
"AT^SLED=2", // Make the LED light blink when registered
"AT^SCFG=\"GPRS/AutoAttach\",\"enabled\"", // Might need this in the future
"AT^SCFG=\"Tcp/WithURCs\",\"off\"", // Don't use IP
"AT^SCFG=\"Userware/Watchdog\",\"1\"", // Leave watchdog on to auto reboot modem if necessary
"AT&W", // Persist this config .. so we can reboot it :)
"AT+CFUN=1,1" // Restart the modem to full functionality using the new configuration
};
