TimerOne issue in combination with BMP085 Adafruit driver

[rbrunni]

Hello Paul,
I am using the TimerOne module in combination with the Adafruit BMP085 Sensor and driver. However when I run the call back function with the read out command for the sensor (bmp.readAltitude()), the program gets stuck. Any other command, e.g. a Serial.print command gets executed w/o any problems. I tried several different BMP085 drivers, all showing the same effect.
Unfortunately, I am not able to debug the issue with the native Arduino IDE.
I am using an Arduino Uno and the IDE shows Version 1.8.13. The little program file is attached below.
Any Idea?

#include "TimerOne.h"
#include <Wire.h>
#include <Adafruit_BMP085.h>

Adafruit_BMP085 bmp;
// Define altitude variable
volatile float Altitude;

void setup() {
Serial.begin(9600);
if (!bmp.begin()) {
Serial.println("Could not find a valid BMP085 sensor, check wiring!");
while (1) {}
}

Timer1.initialize(200000);
Timer1.attachInterrupt(ReadSensorAlt); // Read the altitude value every 200ms
}

void loop() {

Serial.print ("Altitude: ");
Serial.println (Altitude);  

}

void ReadSensorAlt(void)
{
// Read out of Sensor BMP085 does not work. Any other action works with the interrupt function
Altitude = bmp.readAltitude();
}
