Easy Bluetooth Module for the Propeller

I am a big time newbie and I need some help. I have been researching the easy bluetooth module for the propeller but everything I come up with is all based on basic stamp (all the docs and code examples). I am assuming that the easy bluetooth module works with the propeller and spin? Is there any docs or examples to demonstrate this? I have the gadget gangster propeller platform USB board which I believe should not matter.

I want to use blue tooth to interact with a robot via computer and droid phone. I would also someday want to put a camera on the robot but I understand that bluetooth is not powerful enough for video? I saw a bunch of forum stuff on wifi for the propeller nut never saw any product. I was thinking of having the camera independent and using one that has its own wifi connection. Any thoughts?

Thank you for your help.

    The Easy Bluetooth module works fine with the Propeller as long as you power it from a 3.3V supply. There is some sample code on the Parallax webstore page for the Easy Bluetooth module. Check out the .zip files. These are usually Spin archives.

    Bluetooth is not fast enough for normal video. There have been occasional Bluetooth webcams, but these use highly compressed video and, I think, use low resolution cameras to keep the volume of data down. There are all sorts of video cameras with video transmitters in the 900MHz or 2.4GHz frequency range. Do a Google search.

    Thanks Mike

    I went through all of the code examples but everything is basic stamp. I also did some research but could not find any spin objects and/or demo examples.

    If anyone has spin source for the bluetooth easy module I would greatly appreciate it.

    Thank you in advance

    I downloaded the code from the code from Obex and all I have to say is wow. This code adds a USB port to the propeller and then uses it to drive a USB Bluetooth dongle. An impressive use of the propeller's features.

    I have a generic TTL Bluetooth dongle which I've been using with the BS2 and haven't yet tried with the Propeller. But I may try this instead.

    That OBEX code for direct USB bluetooth is very impressive. But, it does require a special, 6.00 MHz crystal to allow you to run at 96 MHz.
    I didn't see that mentioned on the OBEX download page, but I think it should be...

    Thanks very much for your post Ray.

    I am sure you just saved a lot of us, a whole bunch of debugging time!!!

    Also, now I know, I need to order a couple of 6MHz crystals.

    Ray, wouldn't that be 6.00 MHz? (6 * 16). It show 6MHz in the Top Object.
