Prevent timeout while exchange data between two stm32
I am trying to exchange data (str data) between two STM32 throughout Lora connectivity. Both STM32 has a lora module and the connection between them is working fine. Based on two functions:T_eError_eErrorType eDataPlane_eReceiveData_Cmd (uint32_t in_...
How can use BLUENRG-M2SP with custom board?
Hello,I've developed a custom board with STM32F446 and BLUENRG-M2SP, but I can't realize connection. I use the same code for X-NUCLEO-BNRG2A1, in particular X-CUBE-BLE2 Sample App and I've changed SPI pin. If I set the UserBoard mode as HCI_interface...
BLUENRG-2N does not work.
Communication with the chip BLUENRG-2N goes through SPI. When Chip Select GND, there is no interruption on IRQ line, all voltage and quartz are in order. Then I stitched through the SWD and the BlueNRG-1 ST-Link Utility program first with the BlueNRG...

ISM43362 problem on B-L475E-IOT01A
First I initialize it if(ISM43362_Init() == WIFI_STATUS_OK) { USART_SendString(SYS_USART, "WIFI INIT OK\r"); if(WIFI_GetMAC_Address(mac_addr) == WIFI_STATUS_OK) USART_SendString(SYS_USART, "MAC ADDRESS "); ...
Can't connect to STM32H7 on SEGGER or JLink
I can't connect to STM32H7B3I on SEGGER or using JLink. Resetting option bytes on JLinkSTM32 fails. If there is somehow irreparable damage, could that have been due to me programming high or low frequencies (1-400 MHz) in the RCC? If not, what could ...
