Not sure why you’re associating Bluetooth with UL/CSA. They are completely unrelated. Bluetooth standards are owned by the Bluetooth SIG. If a manufacturer wants to include Bluetooth technology in a product, it must license the technology from the Bluetooth SIG. In other words, Bluetooth is proprietary.
Manufacturers don’t “licence” anything from UL/CSA. Selling a product with a UL or CSA mark requires the product to be tested against the respective applicable codes. It’s fairly similar to using a CE mark.
I’m down with that. I was going towards standards and paying for the privilege.
I would suggest though that licensing bluetooth is different from Apple. Any manufacturer on either the sending or receiving side can make something with bluetooth with said license. Only Apple things can be connected to with mfi.
