STM32WB55 BLE connection issues at higher temperature.

Hello!  We are a bit stumped here.  We have a product that we are testing at 65C and it seems that the bluetooth connection keeps dropping at this temperature (Connection timeouts).  We are running from a 32K LSE and 32M HSE crystals.  All our parts ...

I'm trying to get wakeup from STOP mode on a P-NUCLEO-WB55 using the example project PWR_STOP1. It stops OK, but isn't woken up by a button push. I confirmed that the button push was generating interrupts. Any suggestions?

Why STM32WL Alarm always wakeup advance 1 second

I use STM32WL RTC Alarm as low power mode timer for achieve ms level accrancy and any duration sleep. System will convert sleep time to Alarm time before enter low power mode. I have tested different  sleep time, verified convertion result is correct...

Use the same UART with STlink and with another module

Hi everyone !I'm really new to STM32 and everything that goes around... I want to communicate with a SIMCOM A7670E with my NucleoWB55RG and UART1. I'm using PB6 and PB7 for USART1_TX and USART1_RX. But these pins (I kept the jumpers) are also connect...

STM32WL55 subghz radio low level hardware init for a custom board

I am trying to test the SUB GHZ interface on STM32WL5xxU7. Is there any starter code without reliance on Nucleo boards that I could use to start with? Or are there steps how to do this with Low level drivers  ?
