NUCLEO-WL55JC2 RF example – simple Tx/Rx reference needed
Hello, Board: NUCLEO-WL55JC2 (2 boards)MCU: STM32WL55JCIDE: STM32CubeIDEProgramming: Bare-metal C or Cube IDE(C/C++) Goal:I want a minimal RF example using two NUCLEO-WL55JC2 boards where one board transmits a simple message and the other receives it...
STM32WL disable LmHandlerJoin at startup
Hi, I'm using a STM32WL5MOC. I see that in the LoRaWAN_Init the LmHandlerJoin is not in a USER CODE section, meaning that it can't be disabled. In my application I would like to do the join upon my request and not in the init. How I can prevent from...

Schematic Review STM32WBA5MMGH6TR
I am using STM32WBA5MMGH6TR in my project for sending data received from a sensor. BT is used for transmission.The data will be transmitted to a central node.This is a battery operated device. The signal chain is given below.Sensor--> ADC-->STM32WBA5...
Boost stm32wl5moc lora range
Hi, I'm working with LoRa on STM32WL5MOC for a custom board and comparing performance with the dev board. I've measured RSSI and SNR at different distances. - Custom board vs Dev board RSSI, SNR values are noted for reference. How do I improve the ...
STM32WBA5MMG: What happens when BOOT0 is high?
Split from STM32WBA5MMGH6TR Debug interface PCB layout - which is a separate question.Hi , thank you very much.In my module (STM32WBA5MMGH6TRTR), there is only one pin for boot selection BOOT0. I believe when it is pulled low booting happens from mai...
Resolved! STM32WBA5MMGH6TR Debug interface PCB layout
I am using STM32WBA5MMG in my design. This the development board schematic. Below image is from development board schematic.As per the constrains , SWDIO and SWCLK must be length matched. Also need to provide a shield.My questions are given below.SWD...
Resolved! Wio E5 STM32WL LoRaWAN: Conditional Rejoin Based on NVM Context Restoration
I'm using Seeed Studio's Wio E5 board, LoRaWAN 1.0.3 and the repository Seeed Studio Wio E5 LoRa as the base of my source code. I want my device to force a rejoin only when NVM context is not restored (e.g., after a reset or memory clear), and to re...
STM32WL5MOC Custom Board Power Consumption Too High
I have tested the LoRaWAN_End_Node example on a B-WL5M-SUBG1 board and I measure power consumption of 1.7uA when the processor is in STOP mode between transmissions. This is exactly what I expected to see.I designed a very simple custom board based ...
STM32WBA5MMG BOOT0 pin
Dear Team,How to configure the BOOT0 pin of this module.In the reference design it is let floating with an option to pull up.In the application note (How to develop RF hardware using STM32WBA MCUs - Application note) it is pulled down.May I know in a...
