Hi everyone,I'm facing a frustrating issue and would really appreciate any help or insight you could provide.I’m trying to get the STM32WB55CGU6 into STOP2 mode, but I consistently see current consumption over 600 µA, both on my custom PCB and on the...

STM32WB OTA Reboot Failing

Hi there,I'm developing a custom application for FUOTA (Firmware Update Over The Air), targeting an STM32WB55-Nucleo devboard. I’m referencing AN5247 and AN5289 and using the BLE_OTA example from STM (open source code in new page). My user applicatio...

STM32WLXX SubGHZ Phy Radio Drivers: Confusing Definitions for LORA Bandwidths

When defining a LoRa application bandwidth, the function caller may write the following:#define LORA_BANDWIDTH 0 // 125 kHz /* [0: 125 kHz, 1: 250 kHz, 2: 500 kHz, 3: Reserved] ???*/Which we then subsequently fill into the tx configuration here:Rad...

LSE failure Detection Problem

Hi,I am using STM32WBA52CGU6 controller.I configure Pins of LSE_IN and LSE_OUT.Without generating frequency at this LSE_IN Pin I got detection as LSE is on but actually LSE_IN is just open.I attached System clock Config code below:-/** Initializes th...
