STM32 MCUs Wireless

STM32 WLJC55 SubGHZ PingPong example (STM32WL Package)

Hello, i got two STM32 Nucleo-WL55JC2 (dual core) and i want to create a radio communication between these two MCUs. I've downloaded the STM32WL Package and i want to upload the pingpong dual core example on my two cards. (I'm using CubeMX 6.7.0 and ...

i use STM32WL55JCI6 SoC for lora and i use U.FL-R-SMT(10) antenna connector for RF signal

STM32BW55 BLE Demo Code no longer working after FW update (FUS)

I followed the STM32WB Getting Started Series: Part 9 on topic of updating FW to a newer version and reviewed relevant App Notes and HTML from the repository. I use ST-LINK to STM32WB55 Nucleo eval board with STM32CubeProgrammer 2.12.0. The demo code...

STM32WL55JC1 not sending JOIN packets

I have a previously working app and both examples _EndNode and AT_SLAVE.The board worked well for about 30 hours.I could not get the other 2 examples for this board to compile and work.After a change, neither app joins the network reliably. The gatew...

Digital signal input

The sampling frequency is 256kHz, it is an ADC that collects ECG signals.(The question is really not about ADC), what should I belong to with this question?My problem is that the analog signal is output in four channels in parallel after the ADC, whe...

Acquisition of ADC four digital signals

I want to use stm32 to collect ADC digital data. The output of ADC is four digital signals D3, D2, D1, D0 and one clock signal CLK2. I need to add a digital low-pass filter (like fir), how do I collect this 4bit digital signal...Thanks in advance.

After power cycle getting data from SRAM.

I have initialized variable as belowuint8_t u8Flag1ForStoreVer __attribute__ ((section (".RAM1_region")));So, after soft reset I am getting data back.But also same I am getting after hard reset(Power cycle) , even aftre long timeWhat should be value...

Having problems with Nucleo STM32WL55JC1 joining helium network SLAVE and ENDNODE examples

I have a working copy of both the ENdNode and Slave applications in cube running on nucleo boardThese both worked from +-20 December to 28 DecemberI then made a small change to the endnode app - I increased the data packet to 50 bytes in lora_app.c->...
