  • Cloudloop Device Manager MT File transfers are now revised and significantly improved

Bug Fixes:

  • Fixed mismatch between +IMTMTRING and +IMTMTS MT MessageID
  • SMTP email formatting corrected by removing name fields and trimming angle brackets ("< >")
  • Altitude values >9000m now correctly handled (previously returned Invalid Position)

  • Requesting all configuration segments from Cloudloop Device Manager no longer triggers an unexpected reboot
  • Firmware update over Cloudloop Device Manager is now fully functional
  • Zero-length CDM MT messages no longer cause a malloc failure
  • IMT MT message handling improved and fixed – multiple back-to-back messages can now be processed reliably

Known Bugs:

  • Updating the Iridium modem firmware over Serial may require a manual reboot.
  • On the RockBLOCK Pro - Physical Sleep Pin is not yet implemented.
  • On the RockBLOCK Pro - Mass Storage and virtual serial ports may not enumerate properly in low current USB ports and may require an additional power supply using the Power, Serial and GPIO cable (Seen on Raspberry Pi 4).
  • SNTP Issues (Recommended not to use)

RockBLOCK Pro STL only:

  • Kalman filter on STL module is hard set to Marine and power saving to OFF

v0.12

Download FW Version 0.12

New Features (RockREMOTE Mini):

  • REST API now accessible via LAN with commands to request Iridium Signal quality, Iridium registration state and to command a reboot of the Mini terminal.

  • SNTP available on the LAN with time sourced from local GNSS.
  • RR-Mini and the upcoming RockBLOCK PRO will now have the ability to support the OTA upgrade of the Iridium modem FW directly from the Iridium system. Ground Control will have full control over triggering the modem upgrade and customers will be notified in advance. (OTA will only be available for products using Iridium modem FW versions 1.5.5 or above.)

New Features (RockBLOCK PRO):

  • In preparation for early adopters of RB PRO, 2 virtual serial ports and a mass storage device are now available via the USB-C port.

Bug Fixes:

  • Fixed IP Lock-Up after a large amount of consistent IP Data.
  • Fixed various refinements to AT command functions and responses.
  • +CETH will now return +CETH ERROR 1 rather than +CETH ERROR so that future additional error states can be enumerated if required.

  • AT+IMTC2 will now clear all messages in the MO queue aside from any that are transferred to the modem.
  • AT+IMTA now works as documented with the use of MessageID.
  • +IMTC1 no longer observed to cause a crash.
  • +IMTWU no longer incorrectly reporting +IMTWB for error status.

Know Bugs:

  • When a series of IMT MT messages are sent to the RR-Mini in quick succession in some cases one or more message may be lost/dropped - this behaviour has mainly been seen/replicated when requesting all sections from the Config from CDM.
  • The RR-Mini will re-boot if sent a zero length message (empty field) is sent from Cloudloop Device Manager.
  • AT+CETH=ASCII will turn Ethernet OFF.
  • +IMTMTS MT MessageID could deviate and have a mismatch from +IMTMTRING.

ALERT
