How to send a SMS with the Sony Ericsson GSM Modem PDF Manual
SMS (Short Message Service) is a way to transfer short text messages over a GSM-based mobile phone network. Messages are sent via a store-and-forward mechanism to a Short Message Service Centre (SMSC), which will attempt to send the message to the recipient and possibly retry if the user is not reachable at a given moment. The DIL/NetPC DNP/9200 and the evaluation board DNP/EVA9 support SMS, if the Sony Ericsson or Siemens GSM modem is installed. It is also necessary to insert a SIM card with a valid GSM phone network provider contract or a prepaid account to the DNP/EVA9 SIM card holder.
1. Step: Copy all files from the directory /gsm of the DNP/9200 starter kit CD-ROM (version 1.2 or later) to the DNP/9200 directory /flash. Please use the following TFTP commands for this job:
2. Step: The two files minicom and mod_pwr needs executable rights. Please use the following Linux shell command lines and change the rights:
3. Step: Reboot your DIL/NetPC DNP/9200. The DNP/9200 executes mod_pwr over the shell script autoinit.sh within the Linux booting phase and turns the GSM modem power on. Then run a Telnet session and enter the following two commands: With the help of these two commands we run the minicom program, a simple terminal emulation for the DNP/9200. This program allows us to use the GSM modem with AT commands.
The GSM modem responds the at+cmgs command with a single ‘>’ character. Now enter your text message and finish the text with CTRL-Z. After that, the GSM modem sends the SMS to the recipient.
