SBDCTL
From embeddedTS Manuals
The sbdctl application is an example application that can send and receive data on the IRIDIUM network. It requires an IRIDIUM 9602 modem and an appropriate account through a third-party satellite network provider. The source code example is located on the Technologic Systems public github here.
The sbdctl application uses multiple command line switches, and uses stdin/stdout where input or output are necessary:
root@ts7800-v2:~# sbdctl Usage: sbdctl [options] ... Technologic Systems SBD Control Utility Status output goes to stderr. All other IO uses stdin/stdout. Options are executed in the order given on the command line. For example: sbdctl -D <data_len_bytes> -c < myfile.bin This would read myfile.bin into the MO buffer, then initiate an SBD session (if possible) to transmit the data to the network. NOTE: Maximum input is 340 bytes for either text or binary transmissions. NOTE2: The MO and MT buffers can only contain one message each. -p, --port </dev/ttyEX1> Define which serial port to use. -c, --connect Connect to satellite and initiate SBD session. -t, --tread Read text from SBD modem's receive buffer. -d, --dread Read binary data from SBD modem's receive buffer. -T, --twrite <len> Write <len> bytes text data from stdin to SBD modem's transmit buffer. -D, --dwrite <len> Write <len> bytes binary data from stdin to SBD modem's tx buffer. -r, --rssi Request new RSSI reading from SBD modem. -s, --status Get local MO and MT message queue status. -e, --events Enable unsolicited event reporting from modem. -i, --info Dump modem-related info in BASH-compatible variables. -x, --indexes Report message index number for MO and MT. -y, --clearindex Clear Mobile Originated Message Sequence Number. -k, --clearbuffers Clear both MO and MT buffers. -l, --clearmobuf Clear Mobile Originated (MO) buffer. -m, --clearmtbuf Clear Mobile Terminated (MT) buffer. -a, --cpymomtbuf Copy MO to MT buffer on modem. root@ts7800-v2:~#
