BlueNRG-M2SP module SPI not working as co-processor(replacing the BlueNRG-2N)
Hi everyone,I designed a first custom PCB using the BlueNRG-2N as a coprocessor, and everything was working fine, I was able to control it with my main MCU over SPI without any issue.Recently, I made a new version of the board where I replaced the Bl...
Resolved! Toggling LED on STM32WBA25CE1 in the task
I am using NUCLEO-STM32WBA25CE1. I created STM32CubeMX project for this board. I activated RF, WPAN, RTC. I configured a wakeup every 10 seconds and set up a task for the sequencer to toggle the LED. The LED pin is correctly configured. I can toggle ...
Resolved! PA0 WakeUp from Deep stop unreliable on STM32WL31
Good day. I am using STM32WL31 on a custom board.DeepStop mode entry works correctly, but wakeup from PA0 (WakeUp pin) is not reliable or does not work. I used the example code in project:STM32Cube_FW_WL3_V1.3.1\Projects\NUCLEO-WL33CC\Examples\PWR\PW...
Resolved! STM32WL31 fails to exit DEEPSTOP from RTC wakeup
Good day,I have a simple custom board with a STM32WL31 that needs to cyclically enter DEEPSTOP mode and then wake by means of RTC internal wakeup. It seems the device enters DEEPSTOP, but does not wake from it. Basic setup:Clocked from HSI, RTC clock...
NUCLEO-WB09KE board USUART -> LPUART change fail
Dear ST team.(related :Re: UART of NUCLEO-WB09KE UART signal no found - STMicroelectronics Community)I am testing with NUCLEO-WB09KE EVBStarted from the example code ; "BLE_Peripheral_Lite", which is using PB0/PA1 as usuart portI can see the Uart out...
Joining a LoRaWAN network only once
Can I join a LoRaWAN network only once?so that after a software or hardware reset, i would not need to join the same network once again I am working with LoRaWAN_End_Node_LBM example
Difference between MB1720 High_band Low_power & High_band High_power ?
Hello,I noticed that the MB1720 High_band Low_power configuration and the MB1720 High_band High_power configuration have different input line differentials. I would like to know, when combining High_band/Low_power nodes with High_band/High_power node...
Resolved! Non standard preamble on STM32WL33
I need to implement a protocol using 11110000 as preamble. The protocol is 2-FSK 868.1 MHz, +/-35kHz, 25kbps. According to RM0511 STM32WL33 only supports 01010101 or 10101010 as preamble for 2-FSK. Is it feasible to use the STM32WL33? I am planning t...

STM32WL33 Deepstop power consumption higher than normal
We have a custom `STM32WL33CCV6` (`VFQFPN32`) board that should reach about `4 µA` in Deepstop, similar to the NUCLEO-WL33, but instead it drops only to roughly `450–500 µA` and appears to restart on Deepstop entry. `NRST` does not glitch low, and th...
