Newbies attempt at bluetooth... help!

Hi,

Well I feel stupid. Just got a seeed studio bluetooth shield and am trying to get something going with an arduino uno. Seems as though this is the general case... pretty basic... well not for me :slight_smile:

If I upload the sketch, wait a few seconds, disconnect/reconnect the board it'll show up as discoverable for 1 sec then disappear from the "Bluetooth devices" interface on windows 7.

In fact, i'm not getting any lights on the BT board, ever. None of the pics I've seen have jumpers anywhere besides the 6/7 pins... do I need to make a few connections to get this all up and working? If so, can someone provided a detailed explanation as to what needs to be connected ... hardcore newbie here. One thing to note is that I got the board disassembled and haven't soldered anything ... loose connections between the shield and arduino perhaps? Or maybe I just need to run a jumper from the 5v pin to somewhere on the shield.

I think I've read every BT/Arduino article out there but no luck, maybe I just got a bad board but the fact that it it discoverable for 1 sec when placed on the Arduino makes me think not.

Any suggestions? I'm using the same demo code as everyone else

thanks

Quite likely

Yeah, I guess it seems silly that I'd expect it to work prior to being soldered.

I uploaded the slave.pde to the board, the green lights flashing yet windows doesn't see it under the "Add device" window. Is there a special procedure to put the board into discoverable mode? Doesn't seem like the wiki instructions mention that.

Nevermind me, found the issue.

The RxD and TxD from the example code need to be flipped.
