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

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...

Resolved! Is it wrong your schematic for UM2435 in the User Manual for RF?
In the User Manual UM2435 for Nucleo STM32 provided the next schematic But in PCB we see the next I think that the next schematic is actual, is it correct?
I want to configure B-L072Z-LRWAN1 Board-1 to transmit data through USB device(CDC) and another board-2 to receive data through LoRa, if board-2 after receiving data, if it send some data then board-1(which is connected to PC) have to receive it.
Between Board 1 and Board 2 data exchange should be done through LoRa and data exchange between Board 1 and PC should be through USB. It would be very helpful if someone help with this.
