first off, my first big project, bear with me.
ive in my possesion one "Rii mini i8" keyboard, on arduino uno r3 board, and a dongle i aim to pair to the keyboard.
ive arduino IDE running and reading my board, ive wireshark reading 2.4g bluetooth.
now, i understand, that im supposed to now, identify the dongle with i assume ports, or a mac address, that matches the keyboard, but im unsure of what methods, and i am unfamiliar with the necessary coding.
i explored around and came round to thinking the syntax being easy enough, i am unaware of the semantics, and triggers required to initate the transaction im attempting.
as well as what protocol bluetooth is running , and to what, and/or how to utilize the information in which wire shark provides me.
a little direction would be greatly appreciated
The only advice that I can give is that, assuming your dongle is a USB device, you will need a host shield to connect the dongle to the Uno.
I've got a USB type female pinned onto my board I was sure it would work in place
Pinned ofc on "rx tx 5v gnd"
USB works completely different from a UART (the Rx/Tx of the Uno). It will not work and definitely NOT as you think it might work.
USB uses one bidirectional data pair with D+/D- which is not the same as the data pair (Tx/Rx) of the UART where each one is unidirectional.
Further the Rx/Tx of the Uno are also used for communication with the PC.
Alright. This clears up my confusion concerning the Arduino IDE and how it's been interacting. Would I be correct in assuming this is the reason my home made otg doesn't work as expected
Where it's just pinned straight across.
You need to use a USB host shield.
Unfortunately the official Arduino one is retired, but there are others on the market.
ordering a part will push this project to next weekend. this USB host shield seems similar to raspberry pi. Which I have on hand. im assuming there are fundamental differences ofc, and which i havent looked into yet.
and the parts been ordered, thanks for the discussion/ assistance. TBC
