I2C configuration in STM32WL
Hello, I'm trying to connect an OLED display to my STM32WL55JC by I2C but it doesn't work...I've successfully connect it with a STM32F411RE but the I2C configuration / HAL interface seams to be different between both MCU...Here my config on the STM32...
Support for extended advertising packets (ADV_EXT_IND) on the WB55?
Can you use the extended advertising and scanning found in BLE 5 somehow? I have found some references to them in the code, but cannot find any defines. Do they exist? Will they be implemented?
Resolved! Hi everyone, I have to implement radio test on STM32WB55CG based on possibility to manually set signal power and frequency, switch signal on and off. Could you advice me how can this be achieved using some exist coprocessor binary or any other way?
In examples I got familiar with RF low level access is controlled by some exact coprocessor firmware. Existing coprocessor binaries provide some higher level of abstraction that seems to not include forcing signal with exact characteristics. Do I mis...
Resolved! how to use STM32WB5MMG in B-U585I-IOT02A as HC-05 replacement?
Hi, I want to use B-U585I-IOT02A as a controller for mobile robot, I use a smartphone for the remote control. For now I am using HC-05 as the bluetooth interface because I can't find out how to program the STM32WB5MMG to act similar with HC-05. Can a...
I updated to the 1.13.3 stack and it seems that LE Privacy is broken.
I went from the v1.12.1 stack to the v1.13.3 stack and LE Privacy seems to be no longer working. It advertises, but always with the static random address, not a random resolvable address. Also, the address never changes. Anyone else seeing this? ...
Resolved! Factory setting for STM32WB55 P Nucleo ( software)
Hello, Can you please point me to the factory settings of stm32wb55 pucleo board.I seem to have erased some sectors 1-192 and fiddled with some option bytes (nBOOT0) and nSWBOOT0Best Regards,D
STM32WB55RGV6 BLE design questions
Several BLE circuit design inquiries of the STM32WB55RG MCU.The BLE impedance requirement of this MCU is 50 ohm, and it is recommended to use LPF (MLPF-WB55-01E3). For the detailed circuit diagram, please refer to the fourth page of the attached file...
Resolved! STM32WB55 GPIO alternative SPI2(GPIO_AF3_SP2 vs GPIO_AF5_SPI2).
STM32WB55RGV6 connects ADS1299 by spi. And I choose spi2. There are three signas miso\ mosi and sck. SPI2 has two alternative: GPIO_AF3_SP2 and GPIO_AF5_SPI2.① STM32CUBEMX automatically generated miso(GPIO_AF3_SP2), mosi and sck(GPIO_AF5_SPI2).Initi...
Problems with time server and STM32CubeIDE debugging
I was trying to use the time server for a project on STM32WB55. I tried to use it in an empty project. When I tried to debug, this window pops up:The curious part of the problem is that this error seems to happen with the time cluster only: using ano...
