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
Hi,We have developed wireless temperature sensor using STM32WL5MOCH6S module , it is fully battery operated device and Battery is connected directly to supply pin of the module, in this we would want to the read battery voltage , is there any regist...
Resolved! stm32wb0x error on build of stm32cube example projects
I'm trying to import the sample project BLE_Skeleton. On build I get the following error:fatal error: osal.h: No such file or directoryThe same error occurs for other BLE sample projects.The error also happened for BLE_p2pServer but was fixed.When ca...
STM32WB55 MTU SIZE
I am currently working with the STM32WB55RGV6 MCU and utilizing the BLE functionality provided in the BLE_p2pserver example (STM32Cube_FW_WB_V1.18.0) from ST. However, I am facing a limitation where the data packet size is restricted to 20 bytes, pre...
Zephyr support for nucleo-wb15cc
Is support for the nucleo-wb15cc already in Zephyr or does it need to be added? I am new to zephyr and would like to avoid re-inventing the wheel if possible. From a setup I just created today (so should have the latest released code) I didn't see t...
Resolved! Sending a notification causes STM32WB55 to go idle and becomes unresponsive to all further BLE requests
Upon triggering a notify event calling the following function "Custom_STM_App_Update_Char()", the STM32 successfully sends data, which I receive on my iPhone using ST BLE Toolbox. However, after that, the STM32 becomes unresponsive to further BLE req...
