stm32wb55 connection to SPI with light sensor and BLE support connection to PC host

HI i have ULS24 light sensor with SPI communication protocol which i want to connect to stm32wb55rg board and use it BLE support to connect PC host. PC application will pair these devices and i will get access to control light sensor. please suggest ...

Long Characteristic Write Value

Just trying to figure out the max size I can pass to the write function.According to AN5289 :Write long distant value aci_gatt_write_long_char_value(conn_handle, RxCharHandle,offset, chunk_size, (&payload)+offset) Max data write length is 243 bytes.I...

STM32WB15 Wake_up pin polarity issue

Hello,I use a stm32WB15 MCU in shutdown mode with a wake up by the wake up pin PA0 (System wake-up 1).Everything works fine with the polarity "High". I use the HAL function "HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN1_HIGH)".But with the polarity "Low" a...

ST32WB55 What's the relation between notify payload and connection payload?

Can we do simple ASK modulation with STM32WB? is there a sample source code ?

Protocol stack stops while switching with STM32WB BLE and Mac protocol

HelloI am developing a FW that alternately runs BLE and Mac using stm32wb5x_BLE_Mac_802_15_4_fw.bin 1.13.3.0(3) for protocol stack.For FW, BLE and Mac are alternately switched over time (every second).The initialization of BLE, the initialization and...

STM32WB55: Trying to get the RTC running based on HSE_DIV32

Hi,I have been trying to use the HSE_DIV32 clock as input for the RTC but without success.I cannot find any example where this is done even though it's available in the datasheet and the register map.I have been doing this after enabling the HSE cloc...

Stop modes and low power modes

Hello, I'm using the the official example of CubeMX P2P_server and I want to enter stop2 mode during advertising to minimize the current consumption like this: void SCH_Idle(void) { LL_C2_PWR_SetPowerMode(LL_PWR_MODE_STOP2); HAL_PWREx_EnableBLEActivi...
