MLX90614 strange behavior

Hello to all,
I've been playing with 3 MLX90614 sensors (10 degrees FOV). The configuration of them is the default one (C - continuous data reading every 50ms without sending back any data).
I'm asking the temperature back from the sensor by sending to it the string [noparse][[/noparse]0, "!TEMR", 0x5A, 0x07]. Its behavior is normal, but only once every two tries. Meaning that if I send the string and get the (correct) reply from the sensor, the next time I'll send the same string it won't reply at all. The following one it will reply correctly, etc.
I have tested this behavior with an oscillator. The time between the two successive READ requests has nothing to do with this behavior.
Anybody has any idea on that?
With respect,
Giorgos
