mattrain posted:Try "Home" wifi connection only on WIU (e.g. unplug the Cat5E and set the setting switch to "Home" rather than MTH)Questions:
- How does the DCS WiFi app "discover" the WIU? I assume it's via Avahi/IPv6 discovery or mDNS.
- Can multiple DCS WiFi apps be connected to the same WIU at the same time? My testing indicates the answer is "No"
- When establishing connectivity to the WIU, presumably there is a handshake to the TIU. Is there a way to reliably determine whether the DCS WiFi app is connected to the WIU, but the WIU is not communicating to the TIU?
To clarify, the "HOME" mode is for wirelessly connecting the WIU to a home router / access point, not for connecting a device with the app installed. As you stated earlier, the MTH mode is for the WIU to connect to a home network via a wired connection and/or connecting devices with that app installed directly to the WIU using the wireless signal from the WIU.
I use MTH mode with my WIU which is wired to my home router and connect devices through my router's wireless network and other devices directly to the WIU using the wireless signal from the WIU.
To answer your questions:
I have researched some of the discovery process and it appears to be a simple IP scan on a particular port. There has been some discussion in the past about how the WIU is discovered by the app. I have found it better to statically assign an IP address in the LuCi web console on the WIU vs. a static DHCP address assigned by the router.
I have had up to 6 devices connected to my WIU at one time. Two connected through my home wireless network to the WIU via a wired connection and 4 other tablets connected to the WIU (in MTH Mode) using the built in wireless from the WIU. Haven't had an issue yet with this configuration.
The WIU will indicate a connection to the TIU when the TIU light is solid purple. A flashing Purple light indicate no connection, or the WIU is searching for the TIU.
Okay, now some troubleshooting can happen directly on the WIU just by looking at the indicator lights. I have had the stuck horn issue you described and using the lights on top of the WIU I was able to diagnose the problem. In my case, when the Horn was stuck I would press the horn button on my phone app (connected to the WIU via wired) and could not see the blue light flash indicating network activity. Then I tried the horn on my tablet (connected via the WIU wireless) and saw the Wi-Fi light flash and the horn shut off. I can't recall if the TIU light also flickered to indicate that it received the command from the WIU (I think it did but will confirm that functionality this evening). It turned out to being a problem with my phone, I rebooted it, and it worked like a champ again.
Are you using more than one WIU?
