title: RobotDyn Uno wifi not working
body: <p>I am using a Uno+WiFi R3 ATmega328P+ESP8266 board, 32Mb flash, USB-TTL CH340G, Micro-USB.</p>
  
  <p>I am able to see the network SSID on my PC and to connect to it, but when I tried to upload a sketch using the Arduino IDE I am getting espcomm_upload_mem failed.</p>
  
  <p>I used the sketch from <a href="https://robotdyn.com/uno-wifi-r3-atmega328p-esp8266-32mb-flash-usb-ttl-ch340g-micro-usb.html" rel="nofollow noreferrer">https://robotdyn.com/uno-wifi-r3-atmega328p-esp8266-32mb-flash-usb-ttl-ch340g-micro-usb.html</a></p>
