Resolved! STM32WB35: LPUART1 Consuming around 4mA in STOP1 mode
I'm developing an application where I need to have both USART1 and LPUART1 configured to receive commands. I'm using STOP1 mode to ensure the commands can be received by both peripherals (USART1 will not work with STOP2 mode from my understanding). I...
Integrating BLE Audio source and sink in a single project
Hello,I am currently working on integrating the Auracast examples BLE_Audio_PBP_Sink and BLE_Audio_PBP_Source.The main objective is to design a speaker capable of switching between Source and Sink roles depending on the state of a button.However, I a...

STM32WLE5CCU6 RF Design
Dear ST,I developed a RF PCB with STM32WL Microcontroller. The goal was to create RF Transceiver for 868 MHz transmission. Before I started developing PCB I read thoroughly through documents: DS13105, AN5407 and AN5457. As I am familiar with STM32 mi...
STM32WBA52 RTC Stop
It was working fine before, but has now stopped working. Upon investigation, we found that the RTC crystal oscillator is not oscillating. It won't return to normal with a reset. An investigation with the crystal oscillator manufacturer found no probl...
STM32WL55 CAD current consumption.
Hello, I'm working on a project using the STM32WL55 MCU. I'm using the radio features for a LoRa application. The applications requires low power composition for it need to run un battery power. So far I have achieved low current measurement ~2uA w...

Resolved! VDD_TCXO not used at STM2WLE5JCI6
Hi,We are using the STM32WLE5JCI6.In our design, the TCXO (HSE) is powered directly by the 3.3 V on-board power supply, and the VDD_TCXO pin is left unconnected. Is this acceptable?Should we avoid using the Set_TcxoMode command in this case?Thanks fo...
