The following sketch blinks LED_BUILTIN led of UNO Q under App Lab (0.7.0); unfortunately, the sketch does not blink the led under IDE 2.3.7. Am I doing a silly mistake? Would appreciate to receive help.
void setup()
{
pinMode(LED_BUILTIN, OUTPUT); //numerical value of LED3_R is not known to me
}
void loop()
{
digitalWrite(LED_BUILTIN, LOW); // turn on led; in UNO Q the logic is active low
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, HIGH); // turn led off by making the logic HIGH
delay(1000); // wait for a second
}
This is the ouput message after compilation and uploading:
Sketch uses 1036 bytes (0%) of program storage space. Maximum is 1966080 bytes.
Global variables use 0 bytes (0%) of dynamic memory, leaving 523624 bytes for local variables. Maximum is 523624 bytes.

Hi @GolamMostafa. I am able to reproduce the behavior you describe. I found that if I select Tools > Startup mode > Immediate from the Arduino IDE menus and then upload the sketch to the board again, the LED blinks as expected.
A new "Wait for Linux" option was added to the Tools > Startup mode custom board options menu in the 0.55.0 release of the "Arduino UNO Q Board" platform, which was released a couple days ago:
That "Wait for Linux" option is now the default selection in the Tools > Startup mode menu.
Interestingly, the IDE2.3.7 does not even blink an external LED connected at DPin-7; but, it is blinked well by App Lab.
@ptillisch
Can you please confirm me that the following sketch also does not work for you to blink an external LED conected at DPin-7.
void setup()
{
pinMode(7, OUTPUT); // = LED3_R
}
void loop()
{
digitalWrite(7, LOW); // turn on led; in UNO Q the logic is active low
delay(1000); // wait for a second
digitalWrite(7, HIGH); // turn led off by making the logic HIGH
delay(1000); // wait for a second
}
Can I conclude that Arduino has decided not to operate the UNO Q using IDE any more?
I have experienced something similar. A sketch works fine in the App Lab (just upgraded to 0.7.0 with full ?? update to the Q) - prints text using Monitor and Serial (except Serial does not print) and blinking of the builtin LED.
Very same sketch does nothing (no output to the monitor or blinking the LED) when compiled and uploaded from the IDE - with updated Zephyr Core 0.55.0.
Checking the "App Launch" tab I get the following (Sorry for the picture - why can I not copy text from this tab???)
The compile still uses the previous version 0.54.1. I do not know what the other versions should be. This looks wrong to me. I checked the folder on the Q and it is still 0.54.1.
I then downgraded the Zephyr core on the IDE to 0.54.1, compiled and uploaded the exact same sketch and everything works except Serial does not print to the serial monitor - only Monitor.
It appears the Q was not updated to the new core version 0.55.0 (also maybe the RouterBridge etc.).
My UNO Q platform is updated with:
Zephyr Ver 0.55.0
cli Ver 0.9.0
App Lab Ver 0.7.0
Router Ver 0.8.1
IDE Ver 2.3.8
IDE shows a false upload in flash. You try to upload in RAM, it gives error. Your all message that appears on Serial Monitor of App Lab also apears on the OutputBox of Serial Moniotor of IDEx.x.x.
Just tell me -- can to blink LED_R from your IDE? Can you show Hello message on the OutputBox of the Serial Monitor of your IDE? Please, upload the following sketch using IDE and let me know the result so that I can stop the experiment. Connect an external LED with DPin-7 with a 2.2k series resistor.
#include<Arduino_RouterBridge.h>
void setup()
{
Bridge.begin();
Monitor.begin();
delay(5000);
pinMode(7, OUTPUT); // = LED3_R
}
void loop()
{
Monitor.println(analogRead(A0));
digitalWrite(7, LOW); // turn on led; in UNO Q the logic is active low
delay(1000); // wait for a second
digitalWrite(7, HIGH); // turn led off by making the logic HIGH
delay(1000); // wait for a second
}
I do not have a LED on pin seven so I changed your sketch to "LED_BUILTIN" and yes, it prints "104/106/107/104..." to the IDE Serial Monitor and blinks the LED once a second.
Connecting 3.3V to pin A0 it now shows a steady 1023".
So, somthing is wrong with my board which I have received just today (12 hrs ago) after the premature failure of my previous board. This is very unfortunate that I cannot operae the board using IDE.
Do you know if the app is uploaded via WiFi when using App Lab?
Maybe you should update your IDE to also use Zephyr 0.55.0 and try again. It certainly does not work for me with the IDE plus 0.55.0 and the Q with 0.54.1.
While compiling/uploading from IDE, i get the following wanring message:
