Hello,I would like to reach the lowest consumption as possible. I am programming an end node which sends data through TTN. My project is based on the LoRaWAN End Node example with the LoRaWAN middleware. My fimrware works like that :at boot, the boar...
Hello,I have developed a breakout board for the STM32WL5MOC for development purposes and it uses both rf switches and the wiring is identical to the B-WL5M-SUBG1 evaluation board.Running the B-WL5M-SUBG1 sample application SubGhz_Phy on my board and ...
Good evening, I ask for help regarding the communication between stm32wb5mmght6tr and the scd41-d-r2 sensor. I connected the sensor to pins PC0 (SCL) and PC1 (SDA) and powered the sensor but after loading the code I attach, the i2c communication give...
I am trying to implement MODBUS slave on custom board with WB55 on low power mode and need to support 9600, 19200, 57600 and 115200 baud rates.As a first step, I tried to receive 8 bytes of MODBUS command on LPUART and send it on USART1 with HAL with...
I am having an issue with configuring the C1IMR1 register, I created test code for enabling interrupts on the user buttons on the stm32wl55cj1 board but the C1IMR1 register is not being set. Below I will attach the code.
Hi, I work with stm32wle5 where AT commands are received from LPUART. This interface is setup for 9600 bps / 8N1 and its baudrate clock is derived from LSE (32768Hz) clock. The chip is wake up by incoming characters. I observe that transmitted bits h...
Hello, My problem is that I have a custom STM32WB55RG board and I want to use ADC reference voltage as 1V or as close as possible to 1 V. My questions are:1- In datasheet, it states that "If VDDA> 2V, it should be 2<Vref<VDDA and if VDDA<2V, Vref sho...
Hi, We are using STM32WB5MMGH6TR pre-certified module on our product. Our certification parnter insisted that we should perform tests under EN300 328 even though the module is RF tested and there is no RF design on the product side. We tried to use ...
Does STM32-WB55 MCU work without USB dongle? Where can i find the quick start program for led blinking ?
Hello All, I am using STM32WB5MMG for BLE Application, I want to initailly mcu is stop mode or sleep mode,when external interrupt (switch) is triggered its wakeup from low power mode.After wake up re-installize the System Clock ...
