Do you have a specific device in mind or already purchased ? Then provide a link to manufacturer, product page.
Many manufacturers provide information about technical connections, protocol definitions or even sample code. Did you check this ?

If a manufacturer doesn't offer technical support, then I wouldn't buy from them.
