Question
I want to send string data periodically to my mobile phone from the development board of stm32wb55 so what should I do?
I have seen videos or examples of stm32wb workshops, but I have seen most of them send and receive data such as sensor data or LED control through the Android app of st.
In the past, when I used an external BLE module(BM70 of MICROCHIP) , I could send and receive string data from my cell phone without a specific app.
There was no need for a BLE protocol to connect the mobile phone and the BLE module, and send string data from the mcu through uart.
Like when I used an external BLE module, I want to send and receive a string of stm32WB55 without the ble protocol, is there an easy way to do it?
I would appreciate it if you let me know an example or a document.
