Re: Problems with Bluefruit EZ-link shield

Hello - I seem to have a very similar problem but experience it on both my Mac and Windows machines. The project:
http://nw2s.net/product/nw2s-b/
has the bluetooth module connected to an Arduino Due. I can pair with it, transmit, receive, and reset it, but when I go to program it using the Arduino IDE 1.5.7 I get "No device found..."
Is this related and is there any other way I can troubleshoot it? The unit programs fine over USB and again, everything works under bluetooth except when trying to program.

Post a photo of your hardware and connections. We'll see if we can find anything.

Thank you for the reply, but after further work on Windows, I can get it to work on Windows but not on the Mac. I guess I do have the original issue...

Some of your solder joints look teardrop-shaped, which can be a sign that the solder hasn't adhered to the PCB. Check our soldering guide for information about how joints should look (https://learn.adafruit.com/adafruit-gui ... -soldering) and reheat any joints that need attention.

If you still have the problems after that, post the code you're using and a description of the last few things that work correctly until the first thing that doesn't.

I resolved the problem just by switching the computer from iMac & Lenovo i7 laptop PC to an MBA.
This is weird!

Hmm.. that sounds like the EZ-Link hardware is working, but there's some kind of Bluetooth issue on the Mac.

I received my Ez-link shield last week and have not been able to upload code to the shield in my Gentoo linux box. I took it to a friend place and used his window computer. The shield accepted code just fine. So we know the shield is working.

I receive the following error msg:
avrdude: ser_open(): can't open device "/dev/rfcomm0": No route to host
ioctl("TIOCMGET"): Inappropriate ioctl for device
I've done a lot of googling the past week and don't seem to see a solution. Is there any help or suggestions you might have. I've also tested this shield on Kubuntu and Crunchbang Linux without success.

Thanks
DWW

As it says on the product page, we don't support the EZ-Link on Linux. There are too many differences between distributions and too many problems.

Well it is the same error for all 3 Linux distro's. Oh, well I thought someone might have come up with a fix.

For the record the description says, and I quote: Linux is not supported at this time. Which given how long this product has been available I just thought that support might have been extended to include Linux. I'll consider this purchase my error and be more careful in the future when buying from Adafruit.

Thanks .


PS. As a Linux user I don't expect Adafruit to support all Linux distributions. Even If they chose just one say, Ubuntu which seems the most popular that would make me happy.

I don't think we have any plans to support Arduino programming under Linux with the EZ-Link at this time. Sorry.

Hello. I am a linux user and have this same problem. I have Ubuntu 14.04, but I have tried this on Raspbian and Ubuntu 15.04, with no luck. Windows works fine. I am getting the same stk_500 errors as most of the mac users. Does anyone have a suggestion?

I just recently bought the new Adafruit EZlink Bluetooth shield v1.3 with the stackers, and I cant figure out how to get it to work. I have tried several different approaches however no matter what I do, I cant seem to be able to receive signal from my android device. I can pair my android to the Bluetooth shield (I believe I have done it right, it blinks fast at the "Conn" led once connected) however that seems to be all I can do. I am trying to make a remote control car with an L293D chip, yet I cant without figuring out how to get it to work. If I need specific code or if I need to wire it a certain way please let me know.

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

Make sure you post pictures showing your soldering
