Yes, it work. I just add the nx_union. I did not modified TOSH_DATA_LENGTH
because it is just 6 bytes
and the payload size in serial message is 12 bytes (right?)
But i made another test. I don't know where is the proble,
but in the original TestSerial.h
typedef nx_struct test_serial_msg {
nx_uint16_t counter;
} test_serial_msg_t;
i modify just nx_uint16_t counter; to *nx_uint32_t* counter (so 4 bytes);
typedef nx_struct test_serial_msg {
*nx_uint32_t *counter;
} test_serial_msg_t;
i make another time mig files for python and java, recompile java, run
application
and there is the same problem!!
is there a problem with serial messages on TOSSIM and *nx_uint32_t* ??

Yes, randomly Packet Type and Lenght are not right, so they are discarded.

Yes, I hope that someone can help me :)
Thanks in advance.
