WB05KN vs WB05KZ, custom firmware

Hi everyone,I'm working with the WB05KN because I’d like to take advantage of the option to have the firmware preloaded during production.However, I also want to make sure that I’ll be able to load a custom firmware in the future. Is this possible?I ...

How do we enable BLE scanning on STM32WB5x?

This is a repost because the forum decided that my follow-up was a 'solution'.We want to scan using the BLE Full stack, v1.21. What is happening is that the BLE stack is claiming that these HCI commands are unsupported. HCI_LE_SetScan_ParametersHCI_...

Resolved! Example using aci_gap_start_gen_disc_proc

Greetings,Looking at PM0271, there seems to be an API call aci_gap_start_gen_disc_proc. However, I don't see this in the Cube firmware package anywhere in the headers and I haven't found it in sample code as yet. We would like to configure the STM...

STM32WB5 unable to connect

Dear Sirs,I have been developing a board with an H7 and a WB5. I have not had any issues, but one day the WB5 stopped answering, and when I try to connect with the CubeProgrammer I get: "no stm32 target found if your product embeds debug authenticati...

USART RX interrupt not working in stm32 WL package

Im using a STM32WLE5CCU6 board, I am able to log easily using the APP_LOG() helper function that is provided. The problem is that im not able to receive anything as the USART interrupt never fires hence, HAL_UART_RxCpltCallback() is never called. Aft...

stm32wl incompatibility with other LoRa tranceivers?

Hi, I have been facing with an issue that like stm32wl LoRa feature is not compability with other transceivers.However, had 4 transceivers: 1. Esp32-sx126x2. stm32f429-sx126x3. stm32wl (x2) First two can easily communicate with each others, they can...

Resolved! Missing projects for STM23WB5MM

I purchased the STM32WB5MM-DK and it has an application running. When I update CUBE-MX with the patch for STM23WB5MM , there are is no examples that match the application. The training talks about the example projects but they did not come with the u...

Wrong SystemCoreClock value after SystemCoreClockUpdate (HSE with HSEPRE=2)

Hello,I use a STM32WLE5JCI6 MCU. Sometimes I need a good clock precision so I switch to HSE as SYSCLK, with a 32MHz quartz. I use 4MHz as HCLK, and I chose to set HSEPRE=2 and HPRE=4. When I call SystemCoreClockUpdate() function the SystemCoreClock v...

STM32WL5MOC use LPUART for wake up from STOP2

Hi, I started from the LoRaWAN_End_Node example to develop a custom application with a STM32WL5MOC module. I would like to modify the example such that I can wake up the MCU from stop2 mode when I received some data on the lpuart . I set LSE as clock...

Resolved! STM32WLE5xx maximum input voltage on an FT_xx pin when in Shutdown Mode

Hi all, apologies if I have missed the answer to this question in previous posts. I understand that according to the datasheet, the maximum input voltage of FT_xx (and even TT) pins is 3.9V even when VDD, VDDA, VDDRF, and VDDSMPS = 0V. From my unders...
