Parallax WX ESP8266 disable remote code load

I have the ESP8266 board and have used it to load some code on a Prop board.

Now I want to hide it from the simpleIDE so that I don't accidently load some other code on it.

Is there a way through the web page for the unit to disable the UDP code so that it doesn't respond?

    You could update the ESP firmware to the same firmware that the BadgeWX uses, and then assert io0 any time you want to block uploads. Or send a serial command to lock/unlock.

    If that sounds like a good solution, I could get the firmware file for you next week, along with the code snippet and wiring info.

    The problem is I have several of these units and when I enter the SimpleIDE it picks one of them in the serial interface.

    Since the unit is now in production run mode I don't want it to show up so I don't have to deal with it.

    There should be an option on the web page to turn it off so it works like an ESP8266 device.

    At this point I am thinking about replacing it with an ESP8266 unit.

    Do you still need the WiFi module to be online at this stage ?

    I mean, could you power down the WiFi module whilst you don't need to be programming the Propeller over wifi ?

    If that is the case, just hold the wifi module reset pin low to keep it off. That's the pin next to Gnd on the SIP header.

    The reason for the WiFi unit is to communicate with a web service. Every 10 minutes or so it goes and gets an update.

    So no, can't turn the unit off or unplug it.

    I did see in the code that there is a function called "initDiscovery". I need to add some code that sets a variable that it checks before it tries to start this service. That should fix my problem.

    Alright, I made a custom version of the Parallax-ESP code that allows me to hide the unit from the loader.

    On the setting screen I added a new parameter that allows me to hide the unit.

    I also went ahead and built the product using almost the latest SDK 2.2.1

    So far works great.

    Nice addition. I wonder if Parallax would want to incorporate this in their official version of the firmware?
