    VGA is just what was handy for my own setup of this. You could use it with the PropBOE by changing the VGA to start at 8 instead of 16. There's some documentation for easily hook-up of VGA on the PropBOE, I'll see if I can lay my hands on it.

    The easiest connection to the Serial/Wifi board w/adapter is to use the 4pin connection at the bottom of the board. You'll be able to access it using FullDuplexSerial (or compatible object)

    Thanks Jeff. So I do not need to use any of the pins on the single row header, correct? That is where I was getting confused. I think I will just pull out my Quick Start board since both of my Prop BOE's have stuff hooked up for testing and I do not want to mess them up right now. Do I use Pin 16 or 8 on the QS for VGA?

    The pins down the side of the adapter board were put there for those who want advanced access to the pins of the Wifi module. If you are going with a QS board, wire up your VGA to pin 16 since most objects are written for that (demoboard compatible) configuration.

    Got it. While digging for my QS boards I actually found a Prop Demo Board so I will just use that. Thanks Jeff. Edit: No resistors needed, correct?

    That should work perfectly. Just observe your TX/RX pin settings and you should be in business.

    OK, one more question. Can I use an external wi-fi antenna and if so, which pins do I connect it to?

    There is an external antenna clip on the Wifi module itself. I've not had reason to use it, but will be testing soon as I had some laptop Wifi antennas dropped off this week to try that out.

    Well. I hope it is not under the module as I have already soldered the adapter board on!!!!!

    Nope, it's on top of the module, lower middle, left. Look for a small gold circular connection socket. It's tiny.

    Does anyone know how to reset these devices to factory default? I attempted to change the IP address from the web browser and now cannot get into it at all.

    There is a reset pin that you can pull low that does a factory reset. PM me your email and I will send you a link to the manual.

    Thanks for the file, Jim. Not sure what the heck I am doing wrong but I can't seem to get it to reset. Tried using a prop plug to connect also with no luck. Any chance someone has a quick an dirty schematic as to how to connect so I can verify I am doing it correctly?
  • RS_JimRS_Jim Posts: 1,764
    Andy be sure you hold reset pin down for at least 1 second,also be sure you cross connect tx,RX .
    I made that mistake once and went nuts trying to find the problem.

    Did that. I was finally able to get in to the web browser using the IP that I gave it. Although it was in the same subnet as my current network it will only allow me to connect when I am on the ssid of the device, not the one I am on. However, I still cannot connect via terminal for some reason. I have tried both a prop and an TTL serial usb adapter.

    Since this is more of a General Discussion issue I am going to post in that forum instead.
