Connection Issue - Newbie Question

Hi all.

I saw the video of the 'real walle' and decided that I needed one!!

So last christmas I bought myself a Wall-E and a EzB kit. And as a newbie it took me months before I pulled Wall-E apart. It took me a while longer to order all my parts - cos I needed ALL of my parts before I began;) (did i mention i'm a newbie?! lols!)

In the last month I've tried to connect my board to my laptop (its only taken me 4 months to finally do it!) - I'm running Windows 7 with a bluetooth adapter. The board pairs with the laptop fine but when I start the program and press connect, it connects for like 2 seconds then a pop up windows comes up telling me its not connected and the small light goes back to blinking at me. stress

And I'm completely clueless... help

I've tried to rechargeable batteries first then loaded newly bought batteries. The BF then told me to use a power supply (only 2amp - have no idea if that's enough? - the fuse didn't blow so I assume that's good sign.). I've tried two other computers/laptops and same results?

Any suggestions to what I'm doing wrong? (I thought this would be an easy project but I can't even get it connected stress )

So I watched the diagnostics video and in your video you say check the second pin in if you have a 6 pin board... and check the first pin if its a 4 pin board. I have a 4 pin board - can i assume I'm checking the first pin from the bottom if my board if its in the same position as yours??

I ask this cos i get nothing if I touch this first one... but I get something if I touch the top one/last one on the other end?

And if I do the sixth pin test then it does connect up to the next pin from the top though.

And edison2, I have formatted my laptop and the other laptop was running Linux so I had to do a new windows install on that just to try to connect my board up! Hmms.. maybe this is a new excuse to get a new acer laptop... I'm sure the hubby wouldn't notice a dent on his c/c. :)

I have a 4 pin BT module EZ-B board and can confirm that I get the same results as @PriNceSs does and my board works fine BTW. So pin 5 to top pin BT module marked R and pin 6 to next pin down marked T. Basically the data send and receive lines

As DJ says there should also be no shorts to any of the other pins on the BT board

Check the photos on the Diagnostic page for your EZ-B version: https://synthiam.com/Tutorials/Diagnostics.aspx

The pins are all going to be the same, but some won't be soldered, some will, and some have an adapter.

@winstn60 i removed your photo because it was for the prototype 3, which there are only 5 of and were never sold.

We have no problem warrantying unused boards:) Most of the boards we receive are not damaged, and it's an issue on the host computer. As Princess says, her computer is a new install - so perhaps the EZ-B is damaged. The boards go through a complete test before shipping, but sometimes vibratations or static during the shipping process can effect something.

So check for shorts. If there are no shorts, all the power lights flash normally, the bluetooth stack is Microsoft Windows, and you are not running in a Virtual Machine, then we'll need to replace the EZ-B:)

@DJ ahh now its clearer! no I have a blue board. I copied the pic from the manual with a 4 pin BT module so understand now why you thought it was a prototype

@bborastero My BT module is stuck very securely to the main IC with double sided tape and doesn't have a plastic sleeve if it wobbles it definitely won't help
