Problems with CAN comunication to STM32WL using MCP2515

Hy, I'm currently working on a project that requires CAN and that information needs to be sent via wireless, for that reason, I chose the NUCLEO stm32WL board. To make the CAN work I have to use the MCP2515 module, that converts CAN to SPI so that th...

Hi team, I am using STM32WLE5jc microcontroller,and STM cube ide, I try to measure the temparature, by external temparature sensor. i got the raw ADC value but i need to convert it into readable temparature value.. can you please give me formula.

Hi, I am using the STM32WB55 custom board as a client. My Task is to create a connection with the server when a button is pressed. and send the write attribute command and then disconnect from the server immediately.

Steps I am following:Scan for the server and get the MAC of the serverWhen the button is pressed call aci_gap_create_connection to start the connectionThen write the attribute and disconnect from the server.Hear the problem I am facing is it takes 3s...

Generate a public_key using Diffie–Hellman or ECDF algorithm from my private_key

Hello everyone, I am trying to secure data exchange between my STM32WB55 and an external android app ( with BLE) using the Chachapoly algorithm encryption and decryption example found here: https://www.st.com/en/embedded-software/x-cube-cryptolib.htm...

Using STM32WB for bidirectional smartphone application

I developed a prototype using a UART to Bluetooth dongle, the HC-05. This worked like a charm. I could pair my smartphone to it and continuously send data between the MCU Board and my smartphone. Now I want to optimize size and cost, therefore I choo...

How to implement USB-CDC functionality for B L072Z LRWAN1 discovery kit

Hi,I am using B-L072Z-LRWAN1 discovery kit. I want to implement USB-CDC functionality for my project. I created the project using STM32CubeMX with the settings of USB-CDC after following this STM USB training link https://www.youtube.com/watch?v=h9T0...

STM32WB for low latency wireless mouse application

As the title says, I want to create a wireless mouse and was wondering if it was possible to make a low latency mouse using two STM32WBs (one for the mouse and one for the computer). Is this possible with this MCU series or is it better to use a dedi...

How do we send continuous data (Hex data - 250sps) through Bluetooth in STM32WB5MMG?

Our application connects ADS1299 with STM32WB5MMG through SPI and sends at least 250sps for data through Bluetooth. But we got a lot of examples using STM applications, but we couldn't get clear and straightforward code/examples for sending and recei...
