wifi shield v2.2 not detected by Arduino Uno r3.
dagolej 2017-02-13 10:32:22 1790 Views2 Replies Just bought dfrobot wifi shield v2.2 and had it connected to my Arduino Uno r3.
Followed this pagemake_clickable_callback(MAGIC_URL_FULL, ' ', 'http://www.dfrobot.com/wiki/index.php/WiFi_Shield_V2.2_For_Arduino_(SKU:TEL0047', '', ' class="postlink"'))
When attempting to send "at" command in serial monitor /Arduino web editor I got no reply. I set the breakers to "RUN" and "USB". Is there any way to run some basic checks just to see that the wifi shield is ok hardware wise. The only sign of life is the Power indicator.

When Serial.* removed the AT-command gave response in Serial Monitor. dagolej
