Release 1.4.1

Release 1.4.0 introduced a "synchronous" ATCI mode (AT$ASYNC=0) where the modem only sends asynchronous messages to the host upon prior communication from the host, i.e., between an AT command and the corresponding +OK or +ERR final response. The logic did not correctly handle AT commands expecting additional data from the host before a +OK is sent such as AT+UTX and AT+CTX. As a result, +OK ended up being buffered in those two commands. This was reported as #144 by @jpbaltazar. This release fixes the problem.

Full changelog: v1.3.2...v1.4.0

Release 1.3.2

This release fixes a bug in the internal initialization of LoRaWAN MAC performed upon factory reset, i.e., when the NVM (EEPROM) contains no previously saved data. As a consequence of this bug, an AppKey value previously configured by the application and saved in EEPROM was not correctly restored on reboot.

Full changelog: v1.3.1...v1.3.2

Release 1.3.1

This release provides a number of minor improvements and bug fixes to 1.3.0:

• Create a separate build variant for each supported platform using the TypeABZ module.
• Automatically trigger a full rebuild on build configuration changes, e.g., if a particular feature is enabled or disabled at build time.
• Update README.md.
• Enter the low-power stop mode for minimum power consumption while the ATCI UART port is detached.
• Redirect the debug log in MKR WAN builds to Segger RTT instead of USART2. USART2 cannot be used simultaneously with LPUART1.

Full changelog: v1.3.0...v1.3.1

Release 1.3.0

This release incorporates a number of new features from @disk91 to better support Arduino MKRWAN boards, fixes a couple of bugs, and bumps LoRaMAC-node to version 4.7.0.

New features
The new command AT$NVM can be used by the host MCU or application to store a limited amount of user data in the modem's flash. This can be useful for storing per-modem application configuration information in the modem.

The new command AT$LOCKKEYS can be used to prevent the application from reading LoRaWAN security keys over the AT command interface. Once invoked, the LoRaWAN security keys stored in the modem cannot be read until the next factory reset. Please note that this command provides accidental protection only. The security keys can still be accessed over the USART ports or by reading the EEPROM.

The new command AT$DETACH, which is only available in the build variants for Arduino MKRWAN boards, can be used to detach the LPUART1 port (the ATCI port) from its GPIO pins. This allows the host MCU to communicate with the onboard flash which shares communication lines with the LPUART1 port in the Murata modem. To re-attach the port, the host MCU pulls the GPIO pin PB12 down.

Improvements
This release also updates the LoRaMAC-node library to version 4.7.0. The update brings in the most recent bug fixes and minimizes the number of custom modifications we need to keep.

Bug fixes
This release also fixes incorrect handling of DevEUI during factory reset. In previous firmware versions, AT+FACNEW 3 did not correctly reset the DevEUI.

Full changelog: v1.2.5...v1.2.6

Release 1.2.5

This release adds support for Arduino MKR WAN boards. These boards embed the Murata Type ABZ module, but use a different GPIO pin to control the SX1276 crystal oscillator. Artifacts with "mkrwan" in the filename are meant for Arduino MKR WAN 1300 and MKR WAN 1310 boards. The remaining artifacts are for all other platforms that control TCXO via the default PA12 pin.

The generic debug build has a debugging logger enabled on USART1. The MKRWAN debug build variant has the logger enabled on USART2 instead. On the MKRWAN platform, only USART2 is connected to the host MCU.

Full changelog: v1.2.4...v1.2.5

Release 1.2.4

This release makes minor changes to the AT command interface in order to improve backward compatibility with Murata's original firmware:

• The AT command interface is now case-insensitive and also accepts lower case AT commands;
• Downlink payloads that follow +RECV notifications are terminated with CRLF (undocumented Murata feature);
• The Secure Element (security keys) are reset on region change.

As a bonus, the wiki now describes the various asynchronous notifications generated by the modem.

Full changelog: v1.2.3...v1.2.4

Release 1.2.3

This is a minor bug-fix release. This release fixes the handling of oversize application payloads in the modem and adds correct support for hexadecimal payload formats to the companion Python management tool.

In earlier versions, the modem would return a +OK if it received an application payload too big to fit into the uplink message. Since no uplink would actually be sent in this case, the follow-up +ACK/+ACK would never be emitted. Starting in version 1.2.3, the modem returns a +ERR=-12 in this case to indicate to the application that it may need to resend the message.

Full changelog: v1.2.2...v1.2.3

Release 1.2.2

This release fixes two bugs related to the ABP activation mode:

1. AT+JOIN returns +ERR=-14 when invoked in ABP mode (with AT+MODE=0) instead of +ERR=-3;
2. the embedded LoRaMac-node library is properly initialized in ABP mode upon factory reset.

The second bug made the modem unusable in ABP mode directly after factory reset. The modem would deliver uplinks to the network, but the application server would fail to verify the integrity of the payload. All modem versions prior to 1.2.2 are affected when operating in ABP mode. The issue can be fixed in older version by explicitly switching the modem from ABP to OTAA and back:

AT+MODE=1
AT+MODE=0
