-
After registration :
 
-
* AT+SBDSX gives if the RING is set, but the number of waiting messages are unknown
 
-
* With a SBDIX command, one can get the first waiting message transfered from space to MT buffer and will set the RING to 0
 
-
* The message text in MT buffer can be read with AT+SBDRT
 
-
* A new AT+SBDSX gives the number of still waiting messages. If any, again : ask for transfer in MT buffer and read it.

This page explain how to use Iridium satellite constellation for short burst data messages with a rockblock device.
You'll need to pay for the monthly fee (6 £) and buy credits to use this how to.
All text with these recipes will transfer without crypto. If you need crypto or a web interface, try Sat Messenger / RBS

Software

  • See the hardware part to setup serial communication.
  • Get serial communication software like coolterm or picocom.
  • Depending on your computer select the right serial port like : /dev/ttyUSB0, /dev/tty.usbserial (type ls /dev/ in a terminal)
  • Setup 19200 baud and default 0D 0A line feed is fine. (Official Rock7 documentation is wrong !!)
  • Repository for python style : here

You need to type "AT Commands" and the rockblock will answer like all modems. You can start with AT The modem will answer : OK
