Bluetooth module questions

Hello,

I am considering buying two Bluetooth modules from RC, one for each of the two Serializers on my robot. I currently have a BlueSMiRF radio from Sparkfun Electronics that works very nicely with my Lynxmotion SSC-32 servo controller with a Zonet USB-Bluetooth dongle on my PC. The BlueSMiRF is a Class 1 radio (see http://www.sparkfun.com/commerce/product_info.php?products_id=582) so its theoretical LOS range is about 100m and indeed I have no trouble seeing my robot's SSC-32 about 40-50 feet away from my PC in a different room in our house (same floor). I have three questions regarding the RC Bluetooth modules for the Serializer:

1. Is the radio Class 1 or Class 2? If Class 2, and assuming I use your antenna, will I at least get the 50 ft range in my house that I am getting with the BlueSMiRF?

2. If the answer to question 1 is "no" or "it could be close", is it possible to rig a BlueSMiRF onto the Serializer?

3. Can I run three Bluetooth serial connections on my robot (1 for the SSC-32 and 2 Serializers) using just one dongle on my PC? From what I have read, they should all just show up as three separate COM ports and the Bluetooth protocol will round-robin time slice among them. But can someone actually verify that this works?

Many thanks!

P.S. I tried to register on your new forums so I could post there, but I did not receive the confirmation email to activate my registration, even after asking to have it sent a second time. I checked and double-checked my SPAM folder and it's not there either. Thought you might want to know...

Re: Bluetooth module questions

P.S. I eventually got the confirmation message(s) from the new forum registration daemon. So I'm OK on that front now.
