Hi, Context:I am currently developing a LoRa board implementing the STM32WL55. I didn't get the SubGHz Middleware to work, so i implemented the approach as detailed in the reference manual page 206. The code compiles, and the tx-complete interrupt is...

Hi,i am working on a Project right now where i need to send some data via LoRa. I'm using a STM32WL55 and i had some trouble with the radio setup, so to check the basic functionality of my radioi rebuilt the SUBGHZ_Tx_Mode example for my board and co...

Hi, i'm currently working on a Project where i need to send some data via LoRa.I've been struggeling to get a transmission going, so i decided to check the basics.To test the radio, i went ahead and rebuilt the SUBGHZ_Tx_Mode example from the STMCube...

Hi, im currently working on a project (STM32WL55) where i need to send data via LoRa. I plan to use the SubGHz HAL driver as it seems pretty low level and provides easy usage of the internal subghz spi.While researching, i found AN5406 where it says ...

Hi, im currently working on a project for universtiy and im quite new to stm32. I hava a sensor on my board that coummuicates via UART, were it dumps its data once per second. My problem is that the first HAL_UART_RECEIVE works as intended, but after...

Turns out i forgot to connect the VFBSMPS and the VDDRF1V55 pins, so the radio didn't get any power. And no power -> no power on restet

Nevermind, i found the SUBGHZ_Tx_Mode example and that answeres all my questions.

Okay, i read the section of AN5406 again, and realised that it does indeed give an explanation on how to implement the HAL_SUBGHZ_MspInit() function.PWR: Enable wakeup signal of the sub-GHz radio peripheral.I couldn't find what the wakeup signal of t...

But doesn't the SubGHz_Phy_Per use the GFSK modulation? Also, the SubGHz_Phy_Per doesnt employ the SubGHz HAL driver instead it uses the SubGHz_Phy middleware. So i can't use it as a reference.

What are the reception parameters of the nucleo LoRa applications/examples ?

What determines if a peripheral is enabled during startup?

STM32WL55: Subghz RADIO_GET_STATUS returns invalid data.

STM32WL55 subghz radio low level hardware init.

HAL_UART_RECEIVE only recieves one time, then always times out.
