I am currently using the SUBGHZ_Tx_Mode Example from the STM32WL examples from the ST Website. I would like to know (1) whether it is possible to change it to configure to transmit via LoRa 868MHz? (2) I am unable to edit the clock configuration HSE freq

[Rvan .8]

My questions are as follows, based on the use of the SUBGHZ_Tx_Mode Example project for the NUCLEO-WL55JC board.

(1) Can I use it to transmit LoRa radio on 868MHz? It doesn't specify in the readme file.

(2) When editing the .ioc file in STM32CubeIDE, I am unable to change the HSE clock frequency to 32MHz from 8MHz (even though it says that the range allows for it) in the clock configuration panel.

(3) The interrupt handler is not called for some reason. I have tried configuring the pushbuttons to trigger interrupts, and enabling it in the NVIC tab, but it doesn't call the handler. I've done exactly the same for other projects and it worked perfectly each time, so I suspect that it's a project-specific issue.

Thanks for the help.
