STM32 MCUs Wireless

How do you implement pairing and authentication with the STM32WB?

I have read AN5289 and it does touch on the subject but there is not enough detail in it to get to a working solution.From my code: /** * Initialize authentication */ BleApplicationContext.BleApplicationContext_legacy.bleSecurityParam.mitm_mo...

EN-I-CUBE-LRWAN: EXTI_LINE_4_15 Doesn't seem to trigger on Stop Mode on STM32L052

Hello,I open this thread to tell you about one issue I've been having with my implementation of EN-I-CUBE_LRWAN code on a custom board using the STM32L052 MCU.I started with the End_Node example on the L053-Nucleo's folder, and made it work, with an ...

Having trouble with Bluetooth

Hey everyone,I'm having trouble on my STM32WB55RG custom board.Using version 1.7 of the Cube FW package, my board worked properly. But one day, my device was not discoverable in Bluetooth (I suspected that I deleted it whith my custom bootloader, but...

I have a STM32WB55 card. I could not make the Bluetooth connection. I thought of the possibility that the problem was software and I deleted all the data on the chip. Then I try to download firmware again but I get an error. Can you help me on this topic?

Is there any tutorial or guide for launching BLE with STM32WB55 series and the 1.7.0 firmware (or 1.5.0).

Hi, I tried to follow the workshop to start developping with my P NUCLEO WB55.The only thing is that the used firmware is 1.0.0. or something close...I'm pretty sure the 1.7.0 is introducing new cube ide improvement... but i'm really having hard tim...

Deleting flash memory breaks BLE connection on STM32WB50

I am using a STM32WB50CGU5, when erasing flash memory where my settings are stored, the BLE connection breaks. It happens even if I erase only one page (number 96).I think the two CPU conflicts doing flash operations, but the datasheet reports:"The e...

Why does it matter if stm32wb5x_FUS_fw.bin is flashed before stm32wb5x_BLE_Stack_full_fw.bin?

I'm trying to use Zephyr for development on the nucleo_wb55rg board. While doing this I noticed the problem described in:https://github.com/zephyrproject-rtos/zephyr/issues/27348I think that the sequence firmware flash writes matters. Writing stm32wb...

Bug: generated code from STM32CubeIDE(MX) for STM32WB55 Nucleo "BLE P2P Router" not working

Hellothe code generated by STM32CubeIDE version 1.4 with FW package STM32WB 1.8 for BLE application "Router profile" and "Router mode enabled" does not work: It cannot be scanned and connected by smartphone application.The reason (to my opinion after...

Alternative Wireless Stack Install Address

As far as I see, the wireless stack can be installed at any location.Currently the Release Notes for the Coprocessor Binaries give an address to install them to, depending on the part flash memory size.For example the BLE_Stack_light install location...

I want to develop F / W for CPU2 (M0 +) of STM32WB55 / STM32WB50

Hello.I am involved in the F/W development of STM32WB55/STM32WB50. Since the load on CPU1 is likely to be high for the F/W of CPU1 (M4), we are thinking of reducing the load on CPU1 by performing operations related to wireless communication with CPU2...
