there is no version 8.5.. you are connecting to your computer's internal modem. You'll need to follow the tutorial on the website on how to add the EZ-B to your computer. the tutorials can be found by clicking on the menu item labelled "Tutorials"

you've received two COM ports when adding? I suspect COM6 and COM7?

You can try the other COM port, but it's supposed to be the lowest - although i've heard a rumour that someone had it reversed and it worked... technically that's improbable, but i've seen stranger things in windows

When you attempt a connection, what do the LED's on the EZ-B do?

got two com ports COM4 & COM6 the blue LED just keeps flashing the bt LED stays on for few seconds then flashes as before the best i had is bt LED slowly flashing got this msg on ez-b firmware updater Attempting connection to COM4 Comm Err: The operation has timed out. BbytesToExpect: 1

Received: Disconnected Connection Failed: System.Exception: Controller Not Responding at EZ_B.EZB.Connect(String portName) Disconnected

The EZ-B LED is supposed to be slowly fading while the BT LED is flashing.

When it's connected, they both just remain solid.

I think it's a problem with your bluetooth COM-port..

When you power the EZ-B, you have red and blue flash?

When you press the CONNECT button in ARC for COM4, does the RED led stop flashing for a second? And the blue continues to flash?

your not the only one having issues ....

got the builder up with bluetooth easy easy part. then i got asked to upgrade, which i followed after that i havent been able to get the program to find it. though removing it and finding it under bluetooth still no problem

error i get : Attempting connection to COM10 Connection Failed: System.IO.IOException: A device attached to the system is not functioning.

at System.IO.Ports.InternalResources.WinIOError(Int32 errorCode, String str) at System.IO.Ports.SerialStream..ctor(String portName, Int32 baudRate, Parity parity, Int32 dataBits, StopBits stopBits, Int32 readTimeout, Int32 writeTimeout, Handshake handshake, Boolean dtrEnable, Boolean rtsEnable, Boolean discardNull, Byte parityReplace) at System.IO.Ports.SerialPort.Open() at EZ_B.EZB.Connect(String portName) Disconnected

linvor - is set to com10. so that isnt the problem.

below is what i get when trying to verify image Warning: Line 2: Fixing Diff: 4 Warning: Line 676: Skipping Type: 4 Warning: Line 677: Impossible Diff: -10780 Address: 0x0, SB Size: 0x5438 Image OK

Can you remove the bluetooth module, it is located on the top of the black silicon chip. It should just slide out of the plug. Then re-add it by ensuring that the 4 center pins go into the female plug (leaving one pin on either side not connected).

And if you have a camera, can you post a picture of the bottom of the EZ-B so i can see the solder joints? I'd like to verify that there are no accidently solder shorts or missing joints.

If the red light stops flashing, that means a connection has been made with the bluetooth module. If the blue light does not stop flashing, that means there is a communication disconnection between the bluetooth module and the IC.

It's happened a few times before by a faulty solder point. However, all boards are tested before shipped. If the joint broke during shipping vibrations because it wasn't 100%, that can be expected.

If it was me I would use a soldering iron and suck off all the excess solder with a solder sucker then it would be easy to see what should be connected together and what shouldn't. These are the pins to the Bluetooth module and it definately looks like this is the area where the problem is.

Perhaps someone else can jump in here if they have the same connections on their board mine is different looks like yours is a 3.1?

I like Gibraltar btw been a few times

thanks @winstn60

still having trouble can anybody help stress

Anyone?

Just need a close up pic of the underside of the EZ-B board where the Bluetooth module is plugged in

Looking at your pic again the +5v should be bridged with a spot of solder but it looks like they used too big a blob of solder and it is touching the solder land next to it. Just heat it up with your soldering iron and drag it clear but leave the +5v lands bridged you cant really damage it

What I said above. Your pic (circled) shows the +3.3v bridging lands they look ok its the one below the +5v thats touching the land next to it and shouldn't be.

It should still be bridged though
