gammu-php

A php API that enables you to send and receive SMS via a simple REST API

Find more about how to use it here:

https://blog.haschek.at/2021/raspberry-pi-sms-gateway.html

Prerequisites

• A USB modem dongle you can put into modem mode
• gammu and gammu-smsd
• php and php-json

From within the directory where the two php files (send.php and get.php) are stored, run php -S 0.0.0.0:8080 which will serve the two files to anyone on the network on port 8080.

Sending SMS

Just call http://ip.of.your.pi/send.php?phone=07921XXXXXX&text=Testmessage from curl or a browser and it will return a JSON object indicating if it failed (status:error), or succeeded (status:ok)

The variables phone and text are mandator and can be sent via GET or POST (both POST variable or JSON body supported)

{
  "status": "ok",
  "log": "2021-12-04 15:43:39\ngammu-smsd-inject TEXT 07921XXXXXX -unicode -text 'Testmessage'\ngammu-smsd-inject[2669]: Warning: No PIN code in /etc/gammu-smsdrc file\ngammu-smsd-inject[2669]: Created outbox message OUTC20211204_164340_00_07921XXXXXX_sms0.smsbackup\nWritten message with ID /var/spool/gammu/outbox/OUTC20211204_164340_00_07921XXXXXX_sms0.smsbackup\n\n\n"
}

Receiving SMS with the API

Call http://ip.of.your.pi:8080/get.php

And it will return you all messages also in a JSON object

curl -s http://ip.of.your.pi:8080/get.php
