Title: BT 2.0 Connectivity Issues
Post by: Team 3 on February 15, 2014, 03:49:48 PM

Hello Tiny community,

My team has been working on getting connectivity between the normal Bluetooth module and our computers.  Using the example code on the webpage, we tend to get either, "MMMMMMMÿ," for a higher baud rate and various odd garbage characters for lower baud rates.  We have tried almost everything imaginable for adjustments to the baud rate on both the host and receiving end, but it is to no avail.  If anyone is familiar with this issue or a has a possible solution, I would be grateful for the assistance.

Thanks!

It was on the software end.  We trimmed down the code and changed the baud rate to 9600 on the Tiny side with 57600 on the computer.  We do not know exactly why this works (our clock could possibly be operating at a speed other than what we thought).

If it makes you feel any better, I had the same problem, and your solution (TinyDuino baud at 9600, desktop terminal baud at 57600) worked for me too.  I'd like to know why also!
