Resolved! STM32WL33CC1 – Wakeup LPAWUL/MRSUBG Failing After 10m
Hello everyone, I’m experiencing an issue with communication between two STM32WL33CC1 devices. I’m using one for LPAWUL wakeup receiver and the other for MRSUBG transmitter, but I noticed that beyond 10 meters, the communication starts failing....
Resolved! P-Nucleo WB55 USB Dongle Stack Programming Problem
I own 2 P-Nucleo-WB55 boards and dongles. I was able to program the FUS, Stack and FW in both Nucleo boards, but now I want to do the same with the dongles but I cannot program the FUS or the Stack in none of them. * In one of them I get:FUS status i...
Resolved! STM32WB55MMG Cannot Start FUS form running firmware to wirelessly update BLE stack
Respected Members,We are using STM32Cube Package 1.16.0 and STM32CubeIDE v1.12.1. We have 10,000 devices in market with BLE stack v1.16.0 and FUS v1.2.0 (STM32WB5MMG). We encountered a BLE related disconnection bug that was resolved when we switch to...
How to use Autonomous mode with STM32WBA55 (USART2 with GPDMA)?
Hello,I am using a STM32WBA55 controller and want to wake up from sleep mode (STOP1) as soon as an external interrupt (UART start bit) with falling edge occurs on pin PA11 (PA11 is also the USART2 Rx pin).Is there a possibility (e.g. with USART auton...
Resolved! Development board for STM32WL5MOC
Hi, I am planning to use STM32WL5MOCH6TR which you have suggested. So, to start with can I use this expansion board which contains the same chip for prototype purpose. Can I order this board https://www.st.com/en/evaluation-tools/b-wl5m-subg1.html?ec...
Stlink-V3PWR occurs embed Debug Authentication
Stlink-V3PWR no longer works because it displays the message "embeds Debug Authentication, please perform a discovery using Debug Authentication" and "Connection to target must be established before performing file download operation". I have already...
MRSUBG/LPAWUR Communication WakeUp
Hello Is it possible to communicate with the LPAWUL using only the STM32CubeMX MRSUBG/LPAWUR settings, to wakeup sending a direct message through the data buffer? I noticed on GitHub that the CRC calculation and the concatenation of the preamble and ...
Resolved! STM32CubeIDE not generating correct code for SWCLK on STM32WL33
In my design I needed to use the SPI on the 32-pin WL33, which normally is SWCLK, so I relocated it from its usual PA3, to PB2. When connecting the debugger, it was unable to find the target, which is usually an indication of incorrect connections to...
Resolved! Connect multiple identical BLE devices to Windows
I am using the STM32WB55 microcontroller for my product. I want to connect more than one module to my Windows laptop. When I pair one module, it pairs correctly, but when I try to connect another module with the same firmware, it shows the message "T...
FUOTA Fragmentation Not Processing on STM32WL55 Board
Hello ST Community,I am implementing FUOTA on STM32WL55-based device using ChirpStack. For this purpose, I am implementing the example code (Lorawan_FUOTA) provided by st-microelectronics in the stm32cube_fw_wl_v1.3.0 library. I have successfully bui...
