How to organize simultaneous access to a resource (I2C sensor) in JavaME?

Question

Java

There is a method of polling the sensor on the I2C bus (simplified)

private float readCurrentTemperatureValue() {
           I2CDevice lm75ad = DeviceManager.open(I2CDevice.class, config);
            lm75ad.begin();
            lm75ad.read(TEMPERATURE_REGISTER, REGISTER_ADDRESS_SIZE, rxBuf);
            lm75ad.end();
lm75ad.close();

Everything is good here.
But if the I2C bus is suddenly busy polling the RTC, for example, jdk.dio.UnavailableDeviceException should pop up, if I'm not mistaken.

I read that there is a method that waits until the resource is free tryLock(time); where to put it? instead of open?
How do you understand that the i2c bus is busy at the moment?

Answer 1

There is a suspicion that monitoring the bus will make it possible to understand whether it is busy at the moment or not. It seems like there are START and STOP states...
