RF communication not working on STM32WL55CCU6 based custom board

I'm designing a custom board that's based on the STM32WL55CCU6 microcontroler. It's very simple and is required to transmit data continuously in vectors of 12 uint8_t elements, using the LoRa protocol configured to the standard values: 915MHz, CR 4/5...

STM32WBA BLE Direction Finding with Low Power

Hello,I am currently working with the STM32WBA65RI for BLE Direction Finding using connectionless mode. I would like to know if it is possible to use a low-power mode such as Standby with RTC, allowing the board to consume only a few nanoamps, then w...

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...

STM32WL33 DMR Signal Rx RSSI and Demodulation

Dear Sir or Madam, We would like to use NUCLEO-WL33CC2 to verify DMR RSSI reliable detection(compulsory requirement) and demodulation(optional requirement). We only need rx chain for scanning purpose. As per ETSI TS 102 361-1, DMR TDMA frame has s...

MTU Size Limitation on BLE (BlueNRG-M0+) – Unable to Send Payload >20 Bytes

Hello, I am working with the following setup: Board: B-L4S5I-IOT-01AMCU: STM32L4S5VIT6BLE Module: BlueNRG-M0+ (in built in the Kit) I am currently facing an issue related to the BLE MTU (Maximum Transmission Unit) size. By default, the payload length...

stm32wb5mm-dk with SAI interface

Hi, I want to acquire an audio signal from the microphone IMP34DT05 which is connected to the SAI interface of my STM32WB5MM-DK demo board in this way: L/R -> VDD; CLK -> SAI_CK2; DATA -> SAI_D2.The part number I chose is STM32WB5MMGH6TR in STM32Cube...

MXCHIP EMW3080 on B-U585-IOT02A with Zephyr

Hello, I am using the B-U585-IOT02A board with Zephyr. I can't see how to use the MXCHIP EMW3080 Wi-Fi chip. Has anyone made this work? Thanks

Resolved! Flash Erase Operation Stuck During BLE Scanning on STM32WB55

Dear ST Support, I am using the STM32WB55 series and have encountered an issue where the Flash erase operation gets stuck when BLE scanning is active. Specifically, the Flash erase call (SHCI_C2_FLASH_EraseActivity(ERASE_ACTIVITY_ON)) does not procee...

Issue with STM32 UART Communication and Data Loss in Continuous Transmission

I am currently working on an STM32-based project using UART for continuous data transmission between the microcontroller and a PC application. The system works fine initially, but I am facing intermittent data loss and incomplete packets during long-...

Resolved! How to implement custom PAN ID for Zigbee in STM32WB55 MCU?

Hi, Our product uses 2 x STM32WB55 MCUs, where one as Server/Coordinator and the other one as Client/Router for Zigbee. However, our customer prefer to use customized PAN ID or Extended PAN ID so that more controllable and traceable by their applica...
