Balun Placement in Nucleo WL5JC Reference Schematics

Hi All,As an absolute beginner in schematics and PCB design, I have decided to build a breakout board for the STM32WLx MCU. For reference, I used the NUCLEO-WL5JC schematics.I noticed that there are two different schematics for high-band boards:MB138...

Resolved! Can't receive more than 2 datas in BLE

I'm currently using the STM32 board B-U585I-IOT2A. The BLE module is working as BLE Server, and I want to transmit data.So, using BLE_NOTIF_VAL as explained here (https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WB_AT_Server), I can send 1 or 2 va...

STM32WLE5JC higher current consumption in STOP2 and Standby Mode

Hello to all. I am new to the STM32WL series and have been trying to implement the STOP2 mode and STANDBY mode (both with RTC enabled) for STM32WLE5JC, but have not been able to achieve the low current consumption that is expected of it. The datashee...

System Reset doesn't work as expected

Hi,I need to reset all, then tried to call "HAL_NVIC_SystemReset();", expecting a total reset (both nucleos CM4 and CM0), but it seems BLE app doesn't reset and goes to an undefined state, accepting connections, but doesn't accepting access to charac...

P-Nucleo-WB55 and X-Nucleo-DRP1M1 compatibility

Hi all. The documentation of DRP1M1 says it can be stacked on top any Nucleo board with UCPD peripheral embedded in their microcontrollers. I don't see UCPD feature in WB55RG so I thought they are not compatible. However, my supplier is positive that...

Resolved! How to set RUN mode while pairing in STOP2 mode while advertising BLE on STM32WB

I am currently using STM32WB5MMGH6TR for product development.It is in STOP2 mode while advertising and RUN mode while pairing. I would like to make it so that when it is disconnected it goes back to STOP2 mode, but I am having trouble finding a good ...

Does STM32WL comes with a unique DevEUI or we have to create one?

Hello everyone,Recently I started to develop some LoRAWAN applications using the STM32WL. While studying the Lora technology I came across a information call devEUI, which, if i understood it correctly, is the identication of the end device on the ne...

STM32WL error flashing with enabled LoRa middleware

Hello everyone,I have an Olimex BB-SMT32WL that is based on a STM32WLE5CCU6. I use STM32CubeIDE and opened a new project for exactly the STM32WLE5CCU6.Firmware Package Name and Version STM32Cube FW_WL V1.3.0If I just configure like a GPIO Output to H...
