3rd party mode for Altimeter v4

Hi Bill, I recently bought an Altimeter v3 and was able to read the data off of it via i2c interface with an Arduino board using the code posted by turnale and was not in 3rd party mode, but I was able to figure out the scaling parameters to convert the raw data to height in feet.

I have since upgraded to the altimeter v4, and now the same code does not seem to work (no bytes are available to be read from the sensor). Any idea why it would work with the v3 but not the v4? (I requested the v4 be put in 3rd party mode when I ordered it, but it's not clear from the documentation whether that's even an option on the v4).

Thanks for any help... it resolved thanks!
