You could change datax to: nx_uint8_t datax[14]
and then use a string or array copy to set it.
You've only got 28 or 29 bytes (depending on the
TOS version and standard settings) to play with
in your message, and the other fields add up to
14 bytes already...or perhaps more if the int8's
are padded -- in fact I would group those two
int8's together in the hopes that the compiler
will not pad them.
