Resolved! Cannot Download BLE_HeartRate program into WB55rg
Hello there,I'm trying to execute the BLE_HeartRate Service example on WB55rg Nucleo board. Initially I successfully run the code.Later I'm trying to download the same code again BUT I'm getting following message repeatedly in the CONSOLE:Download ve...
WB55 BLE client custom board
Hello.I have my custom PCB with STM32WB55CEU. This board is tested so I m able to connect and sending data beetween "my PCB" and Smartphone.Now I have new goal. The goal is to start scan process for nearby devices. I would like to hit breakpoint whic...
STM32WL33 QSPI VS SPI
Hi I am hoping someone might be able to help me with some calculations.I am assessing the STM32WL33 for use in a product.One of the peripherals will be an EEPROM, an M95P32.The EEPROM supports Dual/Quad Output (Read) However the STM32 does not appear...
Resolved! aci_gatt_add_service() returns BLE_STATUS_OUT_OF_MEMORY
I am adding services to an existing WB55 BLE project with a small number of services.As I increase the number of services, aci_gatt_add_service() eventually returns 0x98, BLE_STATUS_OUT_OF_MEMORY. (I note that 0x98 is not shown as a valid return valu...
Problems with the size of the payload with STM32WBA55
Hi,I use the example BLE_p2pServer_ota and want to transfer 20 bytes of data to UART2 within a characteristic. But i only get the value 1 for sizeof(p_Notification->DataTransfered.Length). case P2P_SERVER_UART_C_WRITE_NO_RESP_EVT: /* USER CODE...
USART_ISR_WUF is not set after wake up from STOP2 by LPUART
I've enabled STOP2 mode with the below code statement void PWR_EnterStopMode(void) { /* USER CODE BEGIN PWR_EnterStopMode_1 */ UART_WakeUpTypeDef WakeUpSelection; WakeUpSelection.WakeUpEvent = UART_WAKEUP_ON_STARTBIT; if (HAL_UARTEx_StopModeW...
Resolved! Lora-E5 mini system clock
I am testing Lora-E5 mini with FreeRTOS from LoRaWan-E5-Node-qian example in STM32CubeIde . All works fine except the clock (MSI) is only 4 MHz. This causes that e.g. osDelay(100) takes 4 s.I have been trying to change MSI to HSE 32 MHz, but no luck...
STM32WL5MOCH6S battery voltage reading
