TinyDuino Processors & TinyShields / Re: BT 2.0 Connectivity Issues: RESOLVED

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).

TinyDuino Processors & TinyShields / Re: send data using bluetooth shield

Hello!  My team had some similar issues earlier on.  You've probably moved on by now, but this might help if you have not altered your design by now.

1) Both the iPhone 5 and MacBook Pro (if late 2013 or later) have BT 4.0 compatibility.  My team got a 4.0 compatible computer to recognize our BTLE device, but it did not connect at any point.  The most likely issue is on the software side of the TinyDuino.

2) Yes.  Unless your power budget is low, going to classic Bluetooth gives greater range, is less taxing on the processor, and it is overall much easier to deal with.

3) Definitely.  Although not easy (my team has run into some connectivity issues dealing with data transmission rates not necessarily lining up with what they should, in a perfect world, be), it is certainly possible to do so.

TinyDuino Processors & TinyShields / BT 2.0 Connectivity Issues

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!
