Where can I get the new firmware that I must update the board with?

[ABell.5]

I bought the P-NUCLEO-LRWAN3 STM32 Nucleo starter pack for LoRa and it says that if the NUCLEO-LO73RZ board's serial number is within a certain range, which it is, the board must be updated with a new firmware before use. However, the link provided only takes me to the LoRaWAN software expansion for STMCube. So, where can I get the new firmware that I must update the board with?

no idea aboput the lorawan boards.

But if they are anything like their BLE stm32WB boards you update the radio firmware with stmcubeProgrammer

Edit: they are completely different.

I believe they are supposed to be updated via UART?

The UM2073 is the right document for the STM32CubeExpansion_LRWAN_V2.1.0 and not the UM2587.

Thank you
