Although, I recall once we got these bluetooth-&gt;serial modules from china one time that were completely undocumented, except for a single page of commands. It took the whole afternoon to figure out that you needed to append "AT" to the beginning of every command to make it work. Apparently I am too young to realize this should have been obvious. </p> http://forums.leaflabs.com/topic.php?id=759#post-4631 Mon, 16 May 2011 10:54:22 +0000 anotherDJ 4631@http://forums.leaflabs.com/ <p>So much easier than I ever thought it would be. thanks alot everybody </p> http://forums.leaflabs.com/topic.php?id=759#post-4569 Wed, 11 May 2011 21:25:50 +0000 anotherDJ 4569@http://forums.leaflabs.com/ <p>Thanks Everybody</p> <p>I'm waiting on the BlueSMiRF silver to get here and get working on it, it's based on the same chip so if i cant get it to work with the board i'll just add some wires and use it via UART.</p> <p>thanks again for letting me know that they work together. </p> http://forums.leaflabs.com/topic.php?id=759#post-4542 Tue, 10 May 2011 13:30:16 +0000 poslathian 4542@http://forums.leaflabs.com/ <p>anotherDJ,<br /> we use the RN-41 modules from sparkfun all the time. The real requirement is that the UART pins on your bluetooth module are 3.3V - for example this <a href="http://www.sparkfun.com/products/10559" rel="nofollow">http://www.sparkfun.com/products/10559</a> device should work fine. The exact bluetooth modules we have a bunch of in the lab seem discontinued on sparkfun and replaced by the "bluetooth mate gold" which I suppose should also work, as long as you power it off Maple's 3.3V supply. </p> http://forums.leaflabs.com/topic.php?id=759#post-4531 Mon, 09 May 2011 10:27:19 +0000 anotherDJ 4531@http://forums.leaflabs.com/ <p>I guess what i sort of really wanted to know to start with was which BT Shields have worked, according to the website "Some Bluetooth &lt;-&gt; UART boards have been tested and are known to work"</p> <p>thanks, </p> http://forums.leaflabs.com/topic.php?id=759#post-4530 Mon, 09 May 2011 10:23:44 +0000 anotherDJ 4530@http://forums.leaflabs.com/ <p>thanks again for the response, I need to start sending some data as soon as I can so that the person working on the android app has some data to work with. </p> <p>It doesn't need to be integrated into the final HW and SW till mid july the latest. do you think that this would be possible?</p> <p>I think I'm going to get the BlueSMirf and make it work with an arduino I have at home and send mock data for the Android dev work and at the same time try to get it to work on the Maple with a little help from you guys.</p> <p>thanks again everybody. </p> http://forums.leaflabs.com/topic.php?id=759#post-4528 Mon, 09 May 2011 04:28:44 +0000 gbulmer 4528@http://forums.leaflabs.com/ <blockquote><p>I saw the SFE BT products when I was looking for a BT device, i was looking at using the BlueSMirf, but the sample code i found uses the SoftwareSerial library on arduino and isn't available on the maple.</p></blockquote> <p>The Arduino uses the software serial library because its only serial interface (USART) is tied to the USB connection.<br /> The Maple has several serial interfaces (USARTs), so you don't need a software serial library, you can use a real hardware serial interface.</p> <p>I agree it is still work to get it going.

I was wondering if any one knew of a simple setup to send data to the Android phone. </p> <p>I was hoping that i could find a bluetooth sheild where I could use serial print to send the data to the bluetooth device. Some advice as to what piece of hardware is capable of this or how i should go about setting up a simple way to send a few numbers from the Maple to the phone would be much appreciated.</p> <p>thanks, </p>
