It was hard to get the compass installed because of the short length of wires. But, I finally did it. Now, the Compass works. But, when I change directions or if it is on for about 5 to 10 seconds , after giving me directions, it disconnects the wireless from the EZ board.
weird, do you think I need some pullup or down resistors? Is this what is happening. do you have these resistors built into the EZB or do we have to add them?

Nope just the signal wires. Its just an idea if noise pick up is the problem I would like to add a compass module but not the Sure one I would prefer the HMC6352 based product which you can get with a breakout board and is readily available in the UK. They are both Honeywell chip sets but the Sure one looks a lot older with virtually no info to download about it on the Net.
it works perfect for 5-10 seconds.
Oh, BTW, I don't think the ferrite bead is conductive? I don't think so. I don't have to worry about it shorting out the EZB? I guess it is save to lay on top of the board's components if necessary. What do you think?
I would put some insulating tape over the beads if you try it to be sure
Are you powering the compass from +5v with port D0 try using the 3.3v (check EZ-B diagram) instead its just an idea from what you describe it doesn't sound like an I2C fault if it works for a few seconds. How frustrating
I am using the I2C interface SDA,SCL,+5volts,Ground.
HERE is an Update on the Compass. I put a Tant cap from +5 to ground. It had no effect whatsoever on the bluetooth being unhooked after 5-10 secs.
Later on today if I can find a couple of ferrite beads, I will put them on the signal lines.
It works GREAT for 5-10 secs.
:-(
D.J. What do you think??
MORE: I tried the Local RadioShack and they did not even know what ferrite beads were. :-(
I guess my only other option is to go with a resistor from +5 to each signal line. If that don't fix the problem, I am Shunked!
:-(
I dunno, our EZ-Bit works great.
