I just got the bluetooth module today and i'm having a hard time figuring out how to make it work with the chipkit UNO in order to have a bluetooth connection to android device.

i've looked at the datasheet for the module: [url][/url] pin layout attached.

So if i understand things correctly i should connect pins 2 and 3 (TXD and RXD) to pins 39 and 40 on chipkit (and then use Serial1), pins 1 and 12 to ground and pin6 to 3.3V.

what do i do with the other pins? I've read on some other forums that i should connect RTS and CTS together. Someone else wrote that one should go to gnd and one to vcc (not sure which one where).

what about the other pins? if anyone has any experience with this i'd be happy to get some advice, since it's my first time working with it and don't want to burn my module.

Is it gonna work considering it says that all (most) pins are TTL levels and chipkit has 3.3V outputs as high?

thnx for any info!
