TS-IRIDIUM AT Command set

When interfacing with the Iridium 9602 SBD directly, the communication protocol is a serial AT command set. The commands supported by the Iridium 9602 are described here in brief. See the official IRIDIUM 9602 modem user's manual for full descriptions (The latest should be available from the satellite service provider).

Caveats: See IRIDIUM documentation.

+SBDDET -- Detach ISU from Gateway. See docs for error list.

+SBDDSC -- Delivery Short Code.

IRIDIUM documentation.

+SBDI -- Initiate SBD session.

Connect ISU to ESS, download oldest message from ESS to MT buffer.

Transmit/upload MO buffer to ESS. ISU is modem, ESS is satellite service.

Detach automatically after operation complete.

See IRIDIUM documentation.

+SBDIX -- Extended SBDI.

Required if using SBD Ring Alerts. See IRIDIUM documentation

+SBDMTA -- Mobile-terminated alert

enable/disable ring alerts +sbdmta=0 disable =1 enable see docs.

+SBDRB -- Read binary data from ISU. outpts MT binary. Format is high order byte first

{2-byte length} + {binary message} + {2 byte checksum}

Caveats. See docs.

+SBDREG -- Force manual network registration. Optional include location data.

+sbdreg[=<location>] where <location> is [+|-] DDMM.MMM,[+|-]ddmm.mmm

DD deg lat (00-89) MM minutes lat (00-59) MMM 1/1000 min lat (000-999)

ddd deg lon (000-179) mm min lon (00-59) mmm 1/1000 min lon (000-999)

Resonse is +SBDREG:<status>,<err> 0=det 1=not reg 2=reg 3=denied, 0=no err

See below for error code list.

+SBDREG? -- Check for current registration.

0=detached 1=not reg'd 2=reg'd 3=reg denied

+SBDRT -- Read text from MT buffer.

Format: +SBDRT:<CR>{MT buffer}

+SBDS -- Checks state of MT and MO buffers.

Response +SBDS:<MO flag>,<MOMSN>,<MT flag>,<MTMSN>

Flags: 0=no message 1=message in buffer MTMSN=-1 means nothing in buffer.

+SBDST -- Set Session Timeout

+sbdst=<timeout> in seconds. See IRIDIUM documentation.

+SBDSX -- SBD Status Extended. It's +sbds with ring alert status and waiting msg count.

Note waiting msg count updated after every SBD session (sbdi/sbdix/sbdreg/sbddet).

+SBDTC -- Transfer MO buffer to MT buffer.

Mostly used to test software without using satellite network.

+SBDWB -- Write binary to ISU MO buffer.

+sbdwb=[<sbd msg len in bytes>] len does not inc checksum.

Modem will respond "READY<CR><LF>"

Send {binary sbd message} + {2 byte checksum}.

Checksum calculation is least significant 2 byte sum of whole message.

Send high order byte first.

example: "hello" in ascii would be sent as:

hex 68 65 6c 6c 6f 02 14

Modem will emit 0 on success, 1 on timeout of 60 seconds.

+SBDWT -- Write text message to ISU MO buffer.

Two usages:

• +sbdwt alone will allow full length 340 bytes

Modem will emit "READY<CR><LF>" After <LF> send text message terminated by <CR>.

• +sbdwt=[<text message>] <text message> maximum 120 bytes if sent this way.

Modem will emit "OK" on success or "ERROR" if something went wrong.

+SBDGW[n] -- Query what gateway this iridium is configured to use.

Responses are +SBDGW <gateway_text> either "EMSS" or "non-EMSS".

if 'n' version is used: +SBDGWN: <1 or 2>. n=1 default commercial gateway. n=2 some other gateway.

+SBDLOE -- Iridium Traffic Management Status.

Returns +SBDLOE:<status>, <status>=0 time is valid. 1 time could not be determined.

is the time in seconds to the end of the current SBD traffic mgmt period.

If traffic management is NOT in effect, will be 0. Otherwise any SBD session will result in error code 38. Power cycling the ISU has no effect on traffic management.

-MSGEO -- Request Geolocation. Response -MSGEO

<x>,<y>,<z>,<stime_stamp>

x,y,z is geolocation grid code from a Cartesian coordinate system.

The axes are aligned suhch that at 0 lat and 0 lon, both y and z are 0 and x is +6376, representing the nominal earth radius in KM. Coords are minimum -6376, max +6376, with a resolution of 4.

-MSSTM -- Request System Time.

32 bit integer expressing number of seconds since the most recent Iridium Epoch Rollover. Should not be used to calculate current date and time. Use +cclk for current date and time.
