Library update for Arduino Nano 33 IoT and 33 BLE?

[Bjerg13]

Hallo,
The new Arduino Nano’s (Every, 33 IoT, 33 BLE and 33 BLE Sense) are using new MCU’s and are not compadeble with the current ITEADLIB_Arduino_Nextion library. Will there be an update anytime soon?

Thanks

il faut toujours avoir de l'espoir !
mais il faudrait pour ça que Itead se sortent les doigts du cul... pour réécrire complètement une vrai librairie et non pas reprendre la merde qu'ils ont chier actuellement.

I just had the same problem with Nano 33 BLE and solved in this way:
Modify NexConfig.h in ...Arduino\libraries\ITEADLIB_Arduino_Nextion directory, row 37 "#define nexSerial Serial //Set "Serial" for Arduino Uno "
to "#define nexSerial Serial1 //Set "Serial" for Arduino Uno, Set "Serial1" for Arduino Nano BLE"
Use Tx1/Rx0 of Nano 33 BLE to communicate with Nextion Display.
in Arduino void setup()
{
....your code here..
Serial.begin(115200); // Start serial comunication at baud=115200 to Serial Monitor
Serial1.begin(115200); // Start serial comunication at baud=115200 to display Nextion

// nexInit(); //DON'T CALL nexInit(); !!! Comment it

page0.attachPush(page0PushCallback);   //Page press event every time the GUI enter on the page 0
page1.attachPush(page1PushCallback);   //Page press event every time the GUI enter on the page 1
page2.attachPush(page2PushCallback);   //Page press event every time the GUI enter on the page 2
page3.attachPush(page3PushCallback);   //Page press event every time the GUI enter on the page 3

....
}

Now the display communicates with Nano 33 BLE. Of course not more with Nano AVR.

Hi there,

I ran into the same issue with Nextion 10'' and Arduino Nano 33 IoT . I followed your advice - thx for that.
When I run my project with the Arduino IDE open it works perfectly.
but when I close the IDE and power the Arduino from an external power supply via USB the display
and the Nano boots/appears but nothing happens.

Seems like the communication is "bridged" within Arduino IDE or using USB ...
Can somebody help here pls?

I don't know anything about your setup or ino file, so this is a wild guess. Make sure you connect your display to a free physical serial port (pref not a software emulated serial port) and not the one shared by the arduino for programming and monitoring.

Hello,

ofcourse I use a free serial port. Otherwise it wound work if the IDE is open also ;-)
And of course I have followed Nextion advice how to change Nex.config
/**

• Define nexSerial for communicate with Nextion touch panel.
  */
  //#define nexSerial Serial2
  #define nexSerial Serial1 //Set "Serial" for Arduino Uno, Set "Serial1" for Arduino Nano BLE"

And as I wrote, the hardware is Nano 33 IoT.
A sample sketch you can find here:
ITEADLIB_Arduino_Nextion-0.9.0/examples/CompSlider

However I found a solution - while the reason for this problem is still unknown.
I had to include #include <NexSlider.h> explicitly. Even I have #include <Nextion.h> in my ino.
Seems linke the linker/compiler does something wrong here and it might be an Arduino IDE issue also ...
