I've bought another Uno to experiment with and I want to learn how to connect and use a Bluetooth module. I have researched at length on Google and Youtube but there seem to be many conflicting ideas, over-complicated stuff and items I'm not inclined to trust.
I have a cheap Bluetooth 4 HM-10 BLE CC2540 CC2541 IOS TE476 module I bought on Amazon for £2.25.
I have an app called BLExAR.
So here are the questions:
- Have I bought a suitable Bluetooth module? If not, please could someone point me in the right direction.
- Please could someone direct me to a reliable on-line guide that will get me started. Just a basic start.
Any help, guidance or advice gratefully received.
Thank you.
