<p dir="auto">Yes, you need a license for each Android device that uses a different Google account from the one used to purchase the license.</p>
<p dir="auto">Licensing is based on the app, not on development. Specifically, the app does not track (and cannot enforce) which device is designated as the "development" device.</p>

<p dir="auto">So, when you connect GUI-O app (<strong>client</strong>) to the ESP32 (<strong>server</strong>) a persistent connection is established. If the server closes the client connection, client will detect this and show an error. If autoconnect is enabled client will try to reconnect every 5 seconds...</p>
<p dir="auto">When you just "kill" the server, the client is not disconnected properly and no "goodbye" message is sent. That is why nothing happens on the client side (there are ways to handle this, e.g., keep-alive as MQTT uses for example, but this is currently not implemented in Ethernet connection.</p>
<p dir="auto">If you try the GUI-O design tool (and exit when the connection is established), you will notice that the client (GUI-O app) reacts immediately, because when the tool closes it implicitly disconnects the client.</p>
<p dir="auto">I can suggest you use "home" button. So, when you reboot the ESP32, swipe GUI-O from the left side of the screen to the right to open the settings menu. Press the "home" button in the upper right corner.</p>
<p dir="auto">Hope this helps.</p>
<p dir="auto">Best regards,<br />
Klemen</p>

<p dir="auto">There were two minor problems.<br />
1.) The Slider Control knob always stayed at 100% even if it is set to a low brightness. That was fixed by adding the following instruction in the "led drive" section.<br />
sendMsg("@brightness VIS:1 VAL:val\r\n");</p>

<p dir="auto">This code should not be necessary, since the value originates from CB, which should already have the correct position. The issue seems to originate from somewhere else, but I cannot see the problem...</p>

<p dir="auto">Google has strict policies regarding sensitive permissions (SMS included).<br />
In order to handle SMS related functionality, the application needs to be (in general) registered as the default SMS app. Since GUI-O does not need SMS functionality to run, it would be probably quite impossible to convince Google to allow SMS features in GUI-O. You can read more about it here:</p>

<p dir="auto">If I understand correctly, you would like to offer a free app for your users, which can be downloaded from Google Play Store? Possibly with different name and logo? The app would only allow pre-defined GUI (e.g., reading from an initialization file that is part of the application itself), standard GUI-O functionalities for creating widgets would be unavailable.</p>
<p dir="auto">Although this is technically possible, it requires a lot of resources (manpower) to maintain this kind of service. I can look into this a bit further, but I believe it is currently impossible to offer this service.</p>
