Hello everyone,

I need help regarding the interfacing of the microcontroller i mentioned with the dongle device. I am beginner and i dont know where to start and how to start but so fr i have found that USB in cdc mode can work for communication. Anyone here can help me in the regard on how to connect with the STM micrcontroller or any protocols for usb which would be needed for integration.Thank you

This is certainly not a beginner project!

For basic getting-started tips, see:

I wouldn't rely upon that!

These dongles often use composite interfaces - and may well rely on proprietary features.
