STM32 MCUs Wireless

I am using STM32WB55 as client, I am establishing connection with server using "aci_gap_create_connection". And I want to disconnect from the server so I am using aci_gap_terminate_gap_proc(GAP_DIRECT_CONNECTION_ESTABLISHMENT_PROC);

But I am not able to disconnect. Can someone please help me with how to disconnect from the server?

How to enable BLE in STM32WB5MMG using STMCubeIDE?

We made custome PCB board using STM32WB5MMG. We tried (489) BLE Security with STM32WB - 04 Simple BLE application generated from CubeMX - YouTube, and also we followed repository example too. We enabled the necessary settings which is mentioned above...

STM32WB55 acquire signal from GPIO using DMA and trigger TIM

I have a board P-NucleoWB55 and I'm trying to acquire a signal with external clock, very similar to uart, I tried with usart in slave mode without succcess, I tried with spi slave without success.Now I'm trying to trigger a DMA transfer with a timer ...

Hi Team, i used to design STM32WB5MMG IC for my application. i have temperarture sensor MAX30102. i need to communicate with mcu with i2c .its working on 1v8.shall i connect directly to mcu i2c? or 3V3 to 1V8 level translator is required inbetween?

Error Message while transmitting and receiving in STM32WLE5 (LoRa P2P).

Hello Community,I have made a custom board for the LoRa application for both P2P as well as LoRaWAN modes. The reference for the RF network I referred to is "Highband High Power" from the MB170 schematic. The frequency I am making this module is EU86...

STM32WB55 doesn't remain in STANDBY mode

Hello,I'm trying to put the STM32WB55 into standby mode and eventually wake it up using wakeup pin 1 (PA0), but it wakes up directly after the HAL_PWR_EnterSTANDBYMode() is executed. After that, I checked the PWR->SR1 and it had BLEWUF bit set, but I...

Hello, what are the constraints when reprogramming the ARR register in the LPTIM peripheral? E.g. does the counter need to be stopped, or can it be running? Does the ARRM interrupt get triggered only if CNT==ARR, or also for CNT>ARR?

I could not find a definite answer on the STM32WBx5 reference manual.I am setting the LPTIM to generate a periodic interrupt by configuring the ARR register, say to 1 millisecond period. Occasionally, I need to reprogram the ARR with a longer period,...
