DJ Sures · Answer

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"

sorry to be a pain got rid of software that came with bt dongle useing Microsofts now still getting err msg Attempting connection to COM6 Connection Failed: System.TimeoutException: The write timed out. at System.IO.Ports.SerialStream.Write(Byte[] array, Int32 offset, Int32 count, Int32 timeout) at System.IO.Ports.SerialPort.Write(Byte[] buffer, Int32 offset, Int32 count) at EZ_B.EZB.Connect(String portName) Disconnected any idea watched tutes following it but sill having probs what am i doing wrong stress

DJ Sures · Answer

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?

bborastero · Answer

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..

bborastero · Answer

and......... sorry don't mean to be rude just getting frustrated, so how do i fix it

DJ Sures · Answer

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?

DJ Sures · Answer

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.

thanks for taking the time to help i,ll e mail some pictures ps the geek shall inherit the earth (it was a typo in the good book)

hope this helps

winstn60 · Answer

Check the solder joints in the circle aren't touching

bborastero · Answer

lucky i got magnifying glass yes all three are touching but not bottom half of ringed solder joint

winstn60 · Answer

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

bborastero · Answer

thanks @winstn60 has anyone got a picture of what it should look like i don't want to just jump in with my soldering iron and where i live its hard to find a good electronics shop i have to go to spain for stuff

bborastero · Answer

still having trouble can anybody help stress

winstn60 · Answer

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

bborastero · Answer

any good ?

winstn60 · Answer

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

bborastero · Answer

ok thaks i'll take the plunge tomorrow i'll let you know
