11.14 +LFWVER – Internal boot loader version
This command is added in 9555 to allow the internal boot loader version to be determined. This is used by
the software upgrade tool.
Query Command: +LFWVER
This returns the boot loader version.
Note this command is intended for use by Iridium supplied tools only and not by end users. This command
is not available on the 9522B LBT.

11.15 +CDSI – Report SMS status
Exec Command: none
Unsolicited Announcement:
+CDSI:<status>
where:
<status>:
0..255 Success code or failure cause (TD_SMS_RP_CAUSE_*)
This announcement is sent when the network responds after a mobile-originated SMS send attempt.
The <status> code is taken directly from the TD_SMS_RP_CAUSE_* values in the 9555/9522B
transceiver board source code, e.g. TD_SMS_RP_CAUSE_SUCCESS=128 to indicate that the SMS was
sent successfully, and another value such as TD_SMS_RP_CAUSE_CONGESTION=42 to indicate failure.
Values up to 127 are defined by GSM for SMS-PP Relay Layer messages, and values 128 and above are
internal codes introduced by Motorola.
This message is used internally to the 9555 Handset, and is not intended for use by end users. This
notification is not available on the 9522B LBT.
