Hi,i am using STM32WBA55 with BLE_p2pServer_ota example and want to wake-up over an USART2 event (start bit or rising edge) from stop mode. What is a good way to do this? I am using HSI16 with USART2 GPDMA1.

Hi,i am using the BLE_p2pServer_ota example with NUCLEOWBA55 and i want transmitt a 20 Byte package over USART2 with DMA in circular mode (19200 Baud). Here as an example, i send 20 bytes every second via HTerm to USART2. BLE advertising (every 2s) i...

Hi,How can I set the lowest power consumption with the BLE_p2pServer example on the STM32WBA55?I have tried to set the power level to the lowest level in STM32_WPAN configuration,but the average power consumption (at 2s advertising interval) is aroun...

Hi,after flashing the binary files of BLE_ApplicationInstallManager and BLE_p2pServer_ota on the STM32WBA55CG, I can no longer access the controller.What i did:Flashing .bin file of the BLE_ApplicationInstallManager @ start address 0x0800 0000Flashin...

Hi @STTwo-32 ,I am using the BLE_p2pServer example with NUCLEO-WBA55 and want to use USART2 instead of USART1. If I use USART1 and send a byte via HTerm, the task UTIL_SEQ_SetTask( 1<<CFG_TASK_SEND_NOTIF_ID, CFG_SEQ_PRIO_0); should be executed as soo...

Hello @STTwo-32 ,Thanks for the advice, but what I really want to know is what is the best way to wake up from stop mode by an event on the USART2 interface (Rx pin PA11) to process the USART-Rx data.Is it good to do the following steps?1. init PA11 ...

Yes, the measurement method is probably not optimal. It looks better with a single shot, but when I measure the oscilloscope image precisely, I counted the number of bits in it from your trigger point (-500ns) to 399.5 µs.I counted 46 bits in 400 µs,...

The scope image shows a strong jitter. Here at 115200 baud the jitter is not as strong, but still present.

@Andrew Neil In the original example BLE_p2pServer_ota from the FW package STM32Cube_FW_WBA_V1.4.1, USART1 is also set to HSI.I tried to set PCLK2 and set the baud rate from 115200 to 19200.Then i pushed button B1 on the NUCLEO board a view times and...

Hi all,I have now found the problem!As SYSCLK I use the 32MHz HSE / 2 = 16MHz.For USART 2 I have used PCLK1 with 16 MHz up to now. As soon as I changed the USART2 clock mux to HSI, the USART signal is OK and I have no more errors.But why is that?Next...
