Hi all,
I am researching about bluetooth. Generally, I want to make a system that communicates with mobile phone and takes voice datas from phone through bluetooth.
I have found lots of bluetooth modules, but they are so expensive that between $10 and $60.
I am wishing a solution that below $10.
What are your suggestions about the solution?
