    Default WiFi Arduino 2560

    I decided I wanted wifi control on my arduino but instead of the esp01 I bought the arduino with built in WiFi and having troubles.

    1st I can not seem to get connected, when I try to upload anything the "L" light comes on activated a few relays and the TX light flickers for a second then nothing. The sketch times out and I get the error to check arduino troubleshooting guide

    2nd anyone have a working code for wifi connect as communication? I am using ZParticle sketch to control 16 relays with Vixen3

    I checked my com port, checked I am on for mega, checked processor using 2560 says no board connected using 1280 is when I get brief comms

    Maybe this thread will help. The sketch was for WiFi via the ESP-01 but perhaps it will help get you where you need to be.

    It does not. I uploaded my sketch onto the arduino and it works fine as long as I am plugged in to my com port. What I need to do is program the ESP side so I don't have to have my laptop near by which is borderline impossible. I do not have a front house garage to store and set up everything so any electronics like a computer needs to be inside my house and that is a problem unless I figure out wifi or find a 30 foot usb cable

    I was able to find enough information to flash the esp but after that ???? I can not find anything on how you actually set the arduino to an IP address or how to tell vixen thats the IP for a relay controller.

    I used three of these USB extenders my first year to connect Arduino to computer. They worked well for me.

    fixed my upload sequence problem had dip switches set wrong. Now if I can only get a way to upload for wifi. Tried using a program for epixel stick esp-01 but no go> I assume it has a different way because its built in or maybe how I did esp-01 was wrong not really finding too much info on this at all

    here is the board but I really can't seem to make sense of the programming seems like there is missing information to me.
    below is my screen and thats as far as I got. I am missing the "upload sketch data"

    Looking at the schematic of the board you purchased, it looks like they connect Tx and Rx to the MEGA or the CH3406 by a set of switches. The set of switches DO NOT CONNECT GPIO2 to the MEGA com ports. This is important because the ESPixelstick firmware uses GPIO2 as the output pin. So, you may be able to connect the GPIO2 output of the ESP8266 directly to pin 19 which is com port RX1.
