Hi,
I want to connect a BT keyboard (class 2540) to an ARDUINO.
Witch BT module should I use?
I've tried HC05 and 06 and of course they can't pair with the keyboard because the only work with serial.
What is the cheapest BT module that can do this?
I've found several posts on how to build a HID from an arduino, but i want to the the inverse: I want to connect an HID to the arduino.
Any thoughts?
thanks.
