appears that String variables are not being printed correctly about arduino_freertos_library HOT 8 CLOSED

String sensorValue; // Make the sensorValue a Global Variable, otherwise it will be reallocated each time the Task for() loop is run.

// the setup function runs once when you press reset or power the board
void setup() {

  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);

  sensorValue.reserve(255); // Reserve a fixed space for your String, larger than the maximum length required, to avoid reallocation.

  // Now set up a Task to run independently.
