I just tried the WRL-13287 shield with an Arduino Uno. If I upload the program without the shield, uploading works. When the shield is attached, I get avrdude: stk500_recv(): programmer is not responding

There is nothing attached to the Arduino Uno?

Advice on getting this to work appreciated.
thank you.

Did you read the hookup guide?
https://learn.sparkfun.com/tutorials/es ... okup-guide

Especially the part about:

Watch out! When you're programming your Arduino (assuming it's an ATmeg328P-based 'duino), make sure the UART select switch is slid over towards the "SW" position. If it's set to "HW", all of those bits and bytes being programmed into the Arduino will also be sent over towards the ESP8266 — there's a chance the spurious data might put the ESP8266 into an unknown (though recoverable) state

Thank you. Right after i sent this message i noticed the UART select was set to HW. Now it works. I didn't realize there was a hookup guide. Thanks very much for the link.

Happy New Year!
