To have a better range, you should use a better/big coil. I had tested a coil that transmit in a range of 4 inches without problem.
I will use the same bluetooth board in different boxes or cases, to see how strong are the waves in different environments and scenarios.
I tried a 3 watts speaker, and it did not work well. Many errors in the reading, probably increasing the coil wil have better results.
The main idea is to take off the speaker, but leave the cables to use them for the coil.
Make a coil with at least 50 turns of wire in a space of 1 1/2 inches of more.
Adapt the coil sides to the speakers cables, not matter if it is ground or power side.

Hello sir, I was just wondering if you could display 2 magstripe info at once using Bluespoof? If so, what approach to I make to the program? Ive read your blog about Bluespoof and I tried to remake the project. I also tried to modify the MalfunctionMag code and the commands in ViolentMag in order to display 2 magstripe data (track 1 and track 2) at once but it still doesn't work. I was hoping that you could help me for this is my first task as an intern and it has been 2 weeks and I still could not make it work.
