How to switch I2C pull up when STOP MODE 2 on STM32WLE

Hello,I have a STM32WLE that works with the lora end_node projectI have a sensor that i power up with a mosfet when needed.But during the time that the chip is sleeping i need to disable the internal I2C pullup (+30 uA more due to the fact that the V...

STM32WL55JC17 LoRaWAN ABP activation problem

Hi, I am using the NUCLEO-STM32WL55JC1 LoRaWAN board, which I have connected to the TTN through the OTAA activation method as seen in the snapshot below. Now I wanna connect it via the ABP activation method, however, the device can't connect to the T...

Resolved! About Data transmit with Usart1 using DMA

Hi.I am using STM32WL55.I set USART1 with DMA tx and DMA rx.I tried to transmit some data as follows. printf("[*] Program Ver 0.2.0.0\r\n"); printf("\r\n"); printf("Net> ");"[*] Program Ver 0.2.0.0\r\n" and "\r\n" are transmitted.but "Net> " is di...

Resolved! How to detect STM32 CubeMX Programmer from my application

I am developing an application on the Seeed Lora-E5 module, which contains an STM32WLE5.Currently I am programming the device via the SWD interface, but for future firmware updates I want to use the UART, (this UART is available externally through a ...

BLE HID of STM32WB55 integrated send volume up key

HelloI'm developing a project on chip STM32WB55. I have referenced the demo aboutBLE-HID of ST's "STM32Cube_FW_WB_V1.16.0". The sample code looks define for mouse usage. Could anyone can teach me how to integrated send volume up key into this sample ...

STM32WLE5c general setup.

Hello and good day to you all. I just realised that there were not many articles about the STM32WLE5J in the past and now some topis are added - luckily. And I´m a total beginner to the stm32 enviroment and I really miss a tutorial on how to setup th...

How to connect Quectel L89H module to STM32WL55JC1 and get the data Via UART?

Hello All, Recently I started working on the GNSS with STM32, I am very new to STM32 eco-system. I have a IRNSS click from MikroE which has L89H and I am trying to integrate L89H with STM32WL55JC1 controller. I have implemented the UART with DMA to r...

Hello,I am trying to commissioning NUCLEO-WB55RG Matter thread end device. It fails to commission and connect.Reference Source Code used:Matter beta version for STM32 Github repo: github.com/stm32-hotspot/stm32wb-matter-device-over-thread Setup:1. M...

What can prevent entering STOP mode? (STM32WB)

After some activity using BLE in the background and UART as well as some EXTI on application side, the consumption jumps from 2,4µA to 4mA, so obviously I have a wakelock. If I hotplug to the system afterwards, I can see in PWR_EXTSCR that Stop mode ...

STM32WB5MMG UART receive interrupt doesn't work

I'm using a STM32WB5MMG chip and I'm trying to receive data with the HAL_UART_Receive_IT() function. But for some reason the HAL_UART_RxCpltCallback function never gets called. Receiving data with blocking mode works, but with an interrupt it doesn't...
