Resolved! Wi-Fi module for STM32WBxM-series?

Hi,Are there any plans for a such a module in the near future? (preferable also with combined BLE-support)If so, what approx. timeline?Thanks

Resolved! Using stm32wb55 without low pass filter?

Is it possible to use stm32wb55 radio without DLF162500? I mean I have nothing to complain about its price but rather that it uses a non standard package/footprint and I don't want to have any non standard components so I can change components so lon...

Resolved! How much difference on power consumption does the SMPS have on stm32wb55 for bluetooth?

When using the radio for bluetooth, would it really make a huge difference in power consumption? I want to reduce my bom and would much rather not depend on 2 more inductors, also is the 32khz really that necessary?

Resolved! Any complete example code for MCU SPI interfacing with a sensor chip

Had tried for some time but still did not get it. The MCU and sensor are both mainstream, typical and relatively simple.Any pointer to a complete (with STM32 project and MX .ioc) example code for STM32 MCU SPI interfacing with a sensor chip. Many t...

Hal Rtc alarm Interurpt firing at startup possible bug report on stm32wl55

Dear community,I recently faced a possible anomaly in Stm32 cube configuration when setting up the RTC alarm:the rtc alarm interrupt was firing immediatley during initialization.Everything was setup via Cube, no manual code involved.Problem begins im...

Resolved! Main.c and main.cpp when mixing C and C++

We created an empty C++ project. Then, added some web-sourced .cpp and .hpp code into the directory. Compiled and debugged with ST-Link MiniE fine. Entry is main.cppIn STM32CubeIDE, click .ioc and edit init code with STM32MX. STM32MX generates mai...

Resolved! Any idea for a bench top attenuator for LoRa link budget?

Transmitter at 1x dBm. Receiver at threshold of decoding or error. About -110 to -120 dBm as reported by the software RSSI value. Need attenator of 140 dB.Many thanks

Resolved! How to port examples written with older wireless HAL lib to latest HAL lib?

For STM32WLE5JC older example on FL_HAL 1.1 and 1.2 . Is there a tool to do HAL WL Lib upgrade to latest 1.3? Or it is easy and safer to leave it as with older HAL. Or, we need to create an empty STM32 porject with latest WL HAL Lib and then copy u...

Bigger OTA BootLoader, Changing Start Addr of user App on STM32WB35 doesn't work

I have made the STM32 BootLoader OTA on a STM32WB35CE several months ago and now I'm facing with a problem to expand it. The initial OTA bootloader and an user App work well for me, but I want to merge the OTA bootloader with some more stuff and chan...
