Firmware 4.00 and Build 1423.
I can consistently make my unit freeze and would appreciate if others could repeat the test.
1) Turn on the unit and give it a minute to fully boot. I know the "AP Ready" LED starts blinking straight away but be patient
2) Start either the Windows or Android App - Connect via Wifi - Wait for waveform to appear - Disconnect
3) Do nothing for 15 mins (seems pretty reliably 15 mins)
4) The "AP Ready" LED goes off - the "App Connected" LED goes on - Wifi drops - Goes from SSID list .. etc
Have to Power Cycle the unit.
Edit4: Actually - it just freezes after 15 minutes of no activity.
15 mins inactivity straight after power-on or 15 mins inactivity after an hour of use both resulted in the unit freezing.
Edit1: Sometimes (often) the Android App really really doesn't want to connect.
What often happens is the "App Connected" LED lights ON but the Android App freezes on startup or stays in Demo Mode despite repeatedly turning demo mode off.
The Windows App now won't connect as the unit thinks the existing Android App is connected.
Soon as I end the Android App the "App Connected" LED goes off and the windows app can connect fine.
Edit2: Found a way to have my Android App reliably connect.
1) Connect Android to a different AP - in that case my normal home wifi
2) Start Android App - defaults into Demo Mode
3) Go back into network settings and change wifi connection to the WFS210
4) Swap back to the App and turn off Demo Mode
Looks like shitty startup code in the App .... or maybe it's that my tablet is pretty rubbish - deliberately using a bottom of the range model to show up slow code I write :p
Edit3: Also works if I Turn Off Wifi - Start the App - Wait a bit - Turn On wifi - Back to App
Once connected I'm actually liking it for £20.
With some decent software (and a firmware fix for 15 min issue if confirmed) this could be damn good value.
