STM32 MCUs Wireless

Dear Sirs, I have issue permanently standby stm32wb55 nucleo board when ble beacon and util scheduler run.

I am using ble advertising example beacon project. I have initiated util scheduler/sequencer. I have registered inside scheduler exti buttom task that is used to standby whole device but it does not stop, device wakup imediately after standby. I am t...

I need to run the STM32WB15 or WB55 in non-signalling mode. How to let it run in a test environment with coax cable connections or in a shielded chamber? I need the RF-signal unmodulated with frequency and power control. BR Bernd

Stm32wb55 board drawing high current

Hi,I have a custom PCB using the STM32WB55 running at 32MHZ. For some reason my board is drawing high current ~40mA. I’m trying to rule out anything I may have missed connection wise on the WB. Would anyone have any ideas if this high current draw is...

New design based on STM32WB55CGU6 Microcontroller

I have a new design based on STM32WB55CGU6 Microcontroller. I wanted to use the MLPF-WB55-1E03 IPD Device for Maching Network. However, the device seems to be out of stock world wide.Can I replace it with MLPF-WB55-02E3?

Setting up BLE communication

I'm new at STM32. I have a STM3255WBRGV which i want to aquire data from sensors with, then send the data with BLE. Kinda like the p2pexamle project. I have seen almost all youtube videos and googled a lot about setting up BLE, without using an examp...

I am currently using the SUBGHZ_Tx_Mode Example from the STM32WL examples from the ST Website. I would like to know (1) whether it is possible to change it to configure to transmit via LoRa 868MHz? (2) I am unable to edit the clock configuration HSE freq

My questions are as follows, based on the use of the SUBGHZ_Tx_Mode Example project for the NUCLEO-WL55JC board. (1) Can I use it to transmit LoRa radio on 868MHz? It doesn't specify in the readme file. (2) When editing the .ioc file in STM32CubeIDE,...

Achieving lowest power on STM32WB5MMG MCU

Hi...I am using STM32WB5MMG MCU..to optimize the power consumption I am using HAL_PWREx_EnterSTOP2Mode() to put the controller in sleep mode.. But after power cycling the board multiple times the power consumption increases and not stable always...Wh...

I am using STM32 Nucleo Pack LoRa HF band sensor and gateways. The Gateway has STM32L073RZT6 low power MCU with ST LoRaWAN_GS and for the end node I have I-Nucleo LRWAN1 i.e USI WM-SG-SM-42 low power LoRaWAN module based on STM32L052 and Semtech1272 trans

i am using STM32 Nucleo Pack LoRa HF band sensor and gateways. The Gateway has STM32L073RZT6 low power MCU with ST LoRaWAN_GS. I am trying to connect the LoRaWAN gateway with LORIOT network server and after following all the procedures, i.e configuri...

Need clarification about SAI Interface in STM32WB5M disco board

Hi there,We purchased STM32WB5M-DK for our project. In STM32WB5M, We have only one SAI Interface. We connected PDM Microphone (MP34DT01-M) on SAI1 A. I want to play the audio signal with speaker through speaker amplifier. I'm using TAS2770 speaker am...
