What's New in Firmware Version 3.1
The new release includes the following changes:
Firmware over the Air
Power Optimization
Other Enhancements
Firmware over the Air (FOTA)
This release features a new AT command, +FOTA, for wireless firmware updates. When you deploy Release 3.1,
FOTA will be enabled by default.
With FOTA enabled, the Conduit initiates the FOTA session. The mDot responds downlink messages automatically
as needed. When the FOTA session is complete, the mDot updates if the firmware successfully transferred or
deletes the FOTA session if the firmware transfer failed.
New AT Command: +FOTA - Firmware over the Air
Note: For more information, go to FOTA Overview .
Power Optimization
To reduce power consumption during Class A transactions, Version 3.1 firmware includes a new auto sleep feature.
When enabled, the microcontroller automatically goes into a stop sleep mode after an uplink transmit ends and in
between two receive windows. In the stop sleep mode, RAM and register contents are retained, but all peripheral
clocks are gated, so timers will not count during these intervals. Refer to the microcontroller datasheet for
information regarding microcontroller sleep mode states.
New AT Command: +AS - Auto Sleep
Other Enhancements
Adaptive Data Rate (ADR) is now enabled by default.
Public Network command, +PN, has been updated to include an MTS network in addition to the LoRaWAN
public or private network options. This includes changes to parameter values. Refer to the +PN command in
S000643 DOT Series AT Command Reference Guide for details.
