MPU-6050 with UC3: Problem with received data.

Hi everyone! i've got a problem with received data from MPU-6050 trough atmel uc3.

The format of the received data looks like this:

$I/uMPL-mai
$n:InvenSen
$se MPL v4.
$0.0 Apr 4
$ 2012 11:0
$4:26

instead of:

$I/uMPL-main: InvenSense MPL v4.0.0 Apr 4 2012 11:04:26

Also i did the following print:

MPL_LOGI("INVENSENSE 123 INVENSENSE 456 INVENSENSE 789 INVENSENSE ABCn");

and i've obtained:

$I/uMPL-mai
$n:INVENSEN
$SE 123 INV
$ENSENSE 45
$6 INVENSEN
$SE 789 INV
$ENSENSE AB
$C

instead of:

INVENSENSE 123 INVENSENSE 456 INVENSENSE 789 INVENSENSE ABC

how to works MPL_LOGI?

Thanks in advance...
