STM32WB RF stack upgrade using FUS

I wanted to upgrade RF stack in WB series uC. I have written my own bootloader, and using it I would like to upgrade RF stack using FUS. Does anyone have any FUS HAL driver, or example project?

SMT32F401RE - P-Nucleo-6180X1

Hello,I need to measure a small distance and I think that hte P-Nucleo-6180X1 would fit my requirements. P-Nucleo-6180X1 is made of a VL6180X1 and a STM32F401RE. I would like to communicate its output using LoRa, do you think that is possible?Thank y...

Resolved! STM32CubeIDE linker script reserves first 4 bytes of RAM1. What for?

Linker scripts generated by STM32CubeIDE 1.10.1 for the STM32WB55 (but also other STM32 platforms) reserve the first 4 bytes of RAM1. Below is an excerpt from STM32WB55RGVX_FLASH.ld demostrating that. Similarly every STM32 linker script I've seen app...

What are the checkpoints to successfully power HSE32 TCXO?

Some facts:LoRaWAN_Init reports no errors, seems that calibration went through OK...?(RadioError result = 0)After trying out different power-modes(LDO/SMPS) and trying to put the Radio into StandBy(to measure the voltage on TCXO_VDD pin) RadioError b...

I am using the NUCLEO-WL55JC1 board to transmit LoRa 868MHz using low-power mode (14dBm). However, when I measure the signal in a noise free radio lab, the received signal power is incredibly low - has anyone encountered something similar?

Details:TX Power on Board: 14dBm (LP)Omnidirectional TX antenna (on board): 2dBiDirectional RX antenna (LPDA): 4dBiDistance: 0.5m free space with minimal interference in labFrequency: 868MHzFSPL (868MHz @ 0.5m) = -25dBExpected P_ in RX: -5dBmMeasure...

STM32WB55 Changing SPI CPHA on custom board doesn't change clock phase

Hello ST team,We're having an odd SPI bug with our custom board.We made a board based on the STM32WB55, everything seems to work fine except for this issue.We're trying to use the spi in mode 0 (CPOL=0 CPHA=0) , but we can't make it work.We have thes...

How to select the transmitting power mode based on region(EU868) for stm32WL?

Hello community,I am designing the STM32WL module for the EU868 (south Africa) region based on the LoRAWAN application. As per the datasheet of stm32WL, the max power used in transmitting is 14 dBm @ 868MHz, so with the reference from the Lora-allian...

Resolved! LoRa-E5 mini (STM32WLE5JC) programming using STM32CubeIDE

Hi,I am using LoRa-E5 mini board from seeed studio (https://www.seeedstudio.com/LoRa-E5-mini-STM32WLE5JC-p-4869.html)To program it using STM32CubeIDE, do we need to connect it to pc using ST-Link or we can simply program it via Type C cable?

53L5A1 SimpleRanging example code timeout error

I am trying to get the simple ranging example code for the 53L5A1 to work on the WB55RG board but I keep getting a timeout error.The text output the example code outputs is "L53L5A1_RANGING_SENSOR_Init failed. Check you're using ONLY the center devic...
