Rdp = 1, locks backup register

I’m working on an STM32WLE5 device and I’m facing a reproducible issue when enabling Read-Out Protection level 1 (RDP = 1). When RDP = 0, everything works as expected: i can write/read RTC Backup registers, my initialization sequence behaves correctl...

Custom Wio-E5-LE PCB draws 88 µA in sleep — datasheet says 2.1 µA

Hi everyone, I’m facing an issue with power consumption on my custom PCB that uses the Wio-E5-LE module. According to the datasheet, the module should consume around 2.1 µA in sleep mode, but my board is drawing around 88 µA instead. I’ve dou...

Resolved! B-WL5M-SUBG1 (STM32WL5MOC) current consumption too high

Hello,We have an issue with the B-WL5M-SUBG1 evaluation board: The idle current consumption is higher than expected: 89 uA (vs. expected: 1-2 uA) after joining (OTAA) successfully.Board: B-WL5M-SUBG1Firmware: STM32CubeWL/Projects/B-WL5M-SUBG1/Applica...

Resolved! STM32WL: NVIC_SystemReset() not working when SUBGHZ Radio already initialized

Hi,I am facing a strange reset-related issue on my STM32WLE LoRa boards involving the SUBGHZ radio and the RF switch.My application sometimes needs to trigger an NVIC_SystemReset() or I reset the board through the NRST pin.However, a reliable reset o...

Resolved! Wrong base address in STM32WB55xx Resource Manual RM0434 Rev 14

Hi,The memory address of the AH1B is being referenced on the memory block as 0x4000 0000 (page 67) but further in the documentation it is referenced as 0x4002 0000 (page 69) Please open an internal ticket for doublecheking and possible fix on the nex...

Resolved! Sigfox and LoRa AT commands for STM32WL5MOC

The STM32WL5MOC component is both LoRaWAN and Sigfox verified. I need to be able to use both types of connections. AT commands for LoRaWAN are readily available. Is there a guide of AT commands for Sigfox and an AT command to switch between modes? Th...

Resolved! STM32WB55 ZigBee Communication with Digi ZigBee Module – Feasibility & Technical Guidance

Hello ST Community,I am currently working on a ZigBee communication project using the STM32WB55RG microcontroller. My goal is to establish ZigBee communication between the STM32WB55 (running ST ZigBee stack) and an external Digi ZigBee module (for ex...

Resolved! STM32WL5MOC power consumption

Hello,I'm looking to measure the power consumption of the STM32WL5MOC component on a B-WL5M-SUBG1 development board.I'm looking for the power consumption announced by the Sleep Mode datacheet (140nA - 810nA).I connected directly to JP2 to use only ST...

Boot problem in STM32WLE5

Hello ST, We are using the STM32WLE5 controller in our product.The system always works on 1.8V. Based on demand, we switch to 3.3V and fallback to 1.8V.Our product is IoT-based, charged through solar to a supercapacitor.The main problem is that the c...
