Need Help with AP WiFi

I want to have my HM 4.2 come up in the AP (access point) WiFi radio. I messed around with settings and lost all wireless access.
I re-imaged the SD, edited the CONFIG file for AP and still no AP. I reformatted the SD, put new image on it, edited the CONFIG for AP and viola it works. Upon reboot no access to AP.
I guess I'm not fully understanding the file structure and what to save to have it boot in the AP mode. Can someone help?

What is the default WiFi config fresh off re-image? The entire WiFi CONFIG is commented out.

Thanks,

Tom
 
If you're on the release version of HeaterMeter, you might be running into a problem with the configuration restore process. The process is different in the snapshot in that after you boot the first time it no longer will do this (which makes it a bit easier to reset the config just by reflashing the SD. There's also a bug in the release version which can reset the networking config if there is an error flashing the HeaterMeter (AVR) on first boot (if the AVR flash fails, the network config will be reset on every boot). This also can interact with the config restore to keep it reloading an old configuration.

On a clean fresh boot with no config restore, the default is for the wifi to be configured with an open network called heatermeter. Although that can be changed by flashing a Preconfigured image.
 
Thanks Bryan. I'm understanding this a bit more but I'm still having problems. I believe this AVR flash fail is my problem. When booting the HM beeps and it never did that before this problem.
I tried a preconfigured image (did not know that tool existed...thanks). But that image has all the WiFi parameters commented out. I have directly edited the CONFIG file before booting it on the HM. No Go! When I take to card out and look at the CONFIG (WIN7 machine) the WiFi parameters are commented out . I have tried another SD card, even reformat before imaging and still no go. I cant gain access to it via Ethernet either.

Are there any suggestions out there?
 
If you're using the snapshot image, the AVR flash fail isn't an issue so the wifi configuration will not reset on you. The beep also indicates that your AVR has flashed because it is running the latest firmware which chirps on startup when connected to 12V power.

The config.txt is a one-time configuration item. If you look at the config.txt in a preconfigured image before you use it, the lines are not commented out. Once the HeaterMeter boots and uses that information, it comments them out to prevent it from overwriting any changes you make from the webui.

If you're using the snapshot image preconfigured for AP mode then it should come up in AP mode and be able to be connected to if you're on that wifi network with the IP address displayed on the device (192.168.201.1). If you see another IP address there, you're connecting to another network and possibly conflicting. You're definitely at the point where you're looking for an unusual network conflict or something and not a setup issue.
