ESP32 DISPLAY

[B1Gt0ne]

I cant get the display scale or size to change when using an ESP32 with my Android phone
All I can get is 51.6% 696x1080
If using an UNO I can change the screen to anything up to 2094x1080
Am I missing something? Is there something I need to change/define in one of the 'src' files?

What is the suspected function/command which does not work for ESP32?

The following test sketch runs on the UNO and the ESP32. They both start at a screen resolution of 51.6% 696x1080 but the UNO will change to full screen 100% 2094x1080 and the ESP32 stays at 51% <> #include <Arduino.h> #define DO_NOT_NEED_BASIC_TOUCH_EVENTS // Disables basic touch events like down, move and up.

Thanks,
could you please delete the original mail content, the empty lines and mark code as code section -> see <> menue point above.

[B1Gt0ne]

I think I have done what you mean

[ArminJo]

Thanks.
Please have a look at the examples I documented yesterday. Is this understandable?

    /*
     * Register callback handler and check for connection still established.
     * For ESP32 and after power on at other platforms, Bluetooth is just enabled here,
     * but the android app is not manually (re)connected to us, so we are definitely not connected here!
     * In this case, the periodic call of checkAndHandleEvents() in the main loop catches the connection build up message
     * from the android app at the time of manual (re)connection and in turn calls the initDisplay() and drawGui() functions.
     */
    BlueDisplay1.initCommunication(&initDisplay, &drawGui);

It all works OK now
Many thanks for your time
