Bluefruit EZ-Link shield test problem

[phat1]

Hi,
I bought the EZ-Link shield and I cant seem to get it to receive my sketch (I think its sending the sketch). It is paired with my laptop and its on com4 and its set to direct. After I couldn't get my sketch sent by bluetooth I tried a basic test by opening the serial monitor, the conn LED flashes rapidly and I tried to send "this is a test" and pressed send on the monitor the RX LED flashed but nothing was on the screen? Is there another way to test, or any test sketch for the ez-link? A lot seem to be for the breakout board. My soldering is good as I'm using the Ethernet shield with no problems and A0, A1, A2 and D8, D7, D6, to turn on/off 4 LEDs. I had the EZ-link on top of the Ethernet shield and it did not work, know I just have the ez-link sitting on the UNO and that does not work.

Is there a way to test if I can receive data from the Ez link shield to my laptop.

I would be grateful for any help or info on this.

Kind Regards

The solder joints in the photos are teardrop-shaped, which suggests they haven't bonded well to the pads on the PCB.

Take a look at our tutorial on soldering for tips on how to get good joints: https://learn.adafruit.com/adafruit-gui ... -soldering

Hi,
Thanks for your reply, I have checked the pins for continuity and they are fine plus all pins for inputs to outputs work fine.

Have you another solution I can check?

- Disconnect the shield from the Arduino
- Connect 5v and GND
- Flip the switch to 'Direct'
- Connect pins 0 and 1 with a jumper
- Pair the EZ-Link from a computer
- Open the Arduino Serial Monitor for that port
- Send a sentence and see if it comes back

Hi Mike,
I done what you said and it works, when I type this is my first test and press send, its sends and I can see it on the monitor. So I reconnected the ez link shield to the uno and the test still worked, So I then set up to the Arduino Uno stacked the Ethernet shield on top and the ez link on top of the Ethernet shield done the test and it works.

My problem is I cant upload a sketch from my laptop to the Arduino by soft serial or by direct with or without a jumper in 0 and 1. I'm not to sure on why I cant send a sketch by Bluetooth can you advise me on this please?

You can only upload sketches using a direct connection, according to the instructions on this tutorial page:

Try uploading without the Ethernet Shield attached.

Hi Mike,

Sorry for the late reply, I fixed my problem and it all works great.

I had a circuit on a breadboard and transferred it onto the shield soldered it up and it works fine.

Im using the flex sensor and stretch sensor from adafruit with the shields

I just need to design a App for my Android phone now and I'll be good.

Thanks for your help

regards

Glad to hear it's working for you.

Happy hacking!
