Maintaining stable LoRa® deployments across industrial and remote environments requires reliable device behaviour, particularly when operating with LoRa P2P or Class B networks in AU915 regions.

RAKwireless has released RUI3 v4.2.4, introducing preparatory support for the upcoming RAK3172-F alongside several fixes aimed at improving deployment stability and operational reliability.

The update is particularly relevant for teams deploying RAK3172-F devices or working with LoRa P2P and Class B implementations where stable connectivity and predictable device performance are critical.

Key updates include:
• Added external SPI flash support for RAK3172-F
• New external flash APIs and AT+EXTFLSSH support for validation and production testing
• Fix for P2P sleep behaviour on RAK3172 following CAD detection
• Resolution of AU915 Class B beacon synchronisation issues that could stall nodes

As LoRaWAN® and edge IoT deployments continue to scale, firmware stability and improved device management capabilities remain essential for maintaining reliable field performance.
