Adafruit nRF58240 and serial port dropping

Post by ssnerwood »

This Adafruit nRF58240 has worked in all coding phases with Arduino IDE and VS Code. It's been about six months and I am adding functionality to the project and using the same nRF58240 and I am having Serial port problems.

On initial attachment to the same Windows 10 pc the computer did not recognize the attached board, so I double pressed the nRF85240 Reset button and the pc recognized the seial port immediately. I uploaded the "blink" program from my pc successfully but lost the serial port immediately after upload completion. I can double press the reset button, upload "blink" and immediately lose seial port over and over again. I am monitoring via device manager.

As more info, as I was typing this post I double pressed the nRF58240 reset button and the serial port was recognized. A few minutes later the serial port drop. I have found that with this also happens with no interaction for the Arduino IDE.

I am not sure what path to take to troubleshoot my serial problem. Arduino Uno works fine and continuously.

Thanks for your time and consideration. It might take me a little while to respond. Health issues.

It also think it's an Adafruit nRF82540 Express. A board I have also used in the past.

EXAMPLE from File Menu...sorry it will take a while..pics will be there by tomorrow morning USA Eastern time.

Code: Select all

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

  https://www.arduino.cc/en/Tutorial/BuiltInExamples/Blink
*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

This worked and I didn't have to 2-click to edit and upload again. Thank you very much.
I don't remember doing this in the past?
