Okay, habe ChatGPD gefragt Leute 
ich fasse es nicht, aber folgende Antwort habe ich bekommen 
Frage: do i have to pay licence fees for bluetooth as a manufacturer ?
Antwort: As of my knowledge cutoff in September 2021, Bluetooth technology is governed by the Bluetooth Special Interest Group (SIG), which is responsible for managing the development and licensing of Bluetooth technology. The Bluetooth SIG does require manufacturers to obtain a Bluetooth qualification and pay certain fees in order to use and implement Bluetooth technology in their products.
However, please note that licensing and fee structures may have changed since my knowledge cutoff date. It is always best to consult the official Bluetooth SIG website or reach out to them directly to obtain the most up-to-date and accurate information regarding licensing requirements and fees.
Gegenfrage: Okay, and do I have to pay licence fees for the word wi-fi, as a manufacturer?
Antwort: No, you do not have to pay license fees for using the term "Wi-Fi" as a manufacturer. Wi-Fi, which stands for "Wireless Fidelity," is a term used to describe wireless networking technology that allows devices to connect to the internet or communicate with each other wirelessly. Unlike some other technologies, the use of the term "Wi-Fi" itself does not require any licensing or payment of fees.
However, it's important to note that if you are implementing Wi-Fi technology in your products, you may need to comply with certain technical standards and regulations set by organizations such as the Wi-Fi Alliance. These standards ensure interoperability and compatibility between different Wi-Fi devices. Compliance with these standards may require you to obtain certifications, which may involve certain fees. It's recommended to check the specific requirements and guidelines provided by the Wi-Fi Alliance or relevant regulatory bodies for accurate and up-to-date information.
IST DAS NICHT GEILLL LEUTE Nimm mir das nicht böse @Doc_Arduino, aber werde jetzt doch keinen Anwalt damit beauftragen. ChatGPD ist meiner Meinung nach sehr vertrauensvoll. I really really love ChatGPD
