It will normally say "Not connected". You don't need to repair. It will only show "connected" when you actually have an open serial connection to the EZ-Link.

I can't make a serial connection though because it does not show up in the arduino IDE as a port option.

You're using a Mac? What is the red LED on the EZ-Link shield doing? Is it flashing?

Yeah it's just flashing red. Even when it pairs and ititially says it's connected the light never changes from blinking red.

It should flash when unconnected, and flash rapidly when connected.

I'm trying to think of a reason why it will pair, but not show up as a port. It definitely shows up in Bluetooth Preferences?

It only ever flashes slowly, never fast. There are other Bluetooth ports but none with the right description, I believe they're just for other devices I have. I tried them anyway but they didn't work.

Hi -

My EZ link pairs with my Mac, but will not complete a successful upload.It worked the first few times I tried with no issue. The AdafruitEZ-link port shows up under Tools > port. I have a 5v Pro Trinket connected to the EZ link.

It looks like it uploads the file, but cannot complete the final verification.

I am powering the Trinket with a portable battery cell through the USB port. Is it possible that the trinket thinks I'm trying to use the USB port for upload?

I was able to upload a very simple sketch that output a line of text and mills() to the Serial Monitor. Nothing beyond that.


Here is the error from the console:

Please post clear, detailed pictures of both sides of the shield, showing your soldering.

Here are the photos you requested. My eyesight isn't great, but I'm pretty sure it is clean soldering.

Thanks

Steve

Looks good.

What's odd is that it appears to have verified the upload before it fails. Does the sketch actually run?

Looks like it does run. It wasn't running yesterday, though it may have had to do with something else. Should I be concerned about this?

If the sketch is running, I wouldn't worry about it.
