I am building a wireless application (BLE) with STM32WB55CG. For that, I am planning to use HSI and LSE (LSE as RF wake up clock and HSI as CPU1 and CPU2 clock). For that, I disabled HSE in the RCC part of CubeMX. After I did that, RF becomes inactiv...
I have created a board based on STM32WB55CG which is same microcontroller as that is used in P-NUCLEO-WB55.USBDongle. The problem is, in STM32Cube_FW_WB_V1.10.0 project folder for P-NUCLEO-WB55.USBDongle board, there is no BLE_MeshLightingProvisioner...
The first problem HAL_Delay() is stuck. The count value is always 0 and cannot enter the timer interruptThe second problem cannot enter the external interrupt.Does anyone know what's going on？
I am developing on NUCLEO WB55, I call aci_gap_start_general_discovery_proc() to discover near devices, if I pass PUBLIC_ADDR as third argument all goes well but it does not find my devices, becose they have random addresses.If I pass STATIC_RANDOM_A...
Hi.I'm looking for best way to remotly control Nucleo based procjet around 500m-1km range or above if possible. I've been looking for radio solution but all accesable options are really short range like LoRa modules which can provide good connectivit...
Have built the (single core) LoRaWAN AT Slave example from STM32Cube_FW_WL_V1.0.0, which has been flashed to a new Nucleo STM32WL55 board (straight out of the package). No apparent problems building and flashing. Configured for AS923 region.Running a...
The latest I-CUBE-LRWAN version 1.3.1 hasn't been updated for nearly a year now, whereas previously there were several upgrades per year. As we are using this product in commercial IoT units it is pretty critical to understand whether STM intends to ...
Hello ST Community,I recently made PCB using STM32WB55CGU6 MCU. I used STM32WB-Dongle as reference and designed 4-layer PCB. After board bring up and soldering I found that every peripherals of my board are working except Bluetooth.I am using P2P-ser...
After going through AN5457 I want to confirm whether I have correctly followed the design guidelines presented.I am aiming at 920MHz and have used the 923MHz 22 dBm value for Z0 (10.58-j10.71).This is my first time dealing with RF but I understand th...
Hello,We came across a strange problem with LPUART on STM32WB55 chip.When using FIFO in interrupt mode (receiving data), if you use FIFO depth more than 1 byte (even 2 or you will occasionally (one out of ~1000 reads) get complete junk bytes (not al...
