Better yet :

#define dts_length 2
unsigned char data_to_send[dts_length] = {0x01,0x00};

.....
for(byte_idx = 0; byte_idx < dts_length; byte_idx++)

This is not an improvement. What the OP had originally is better
because it scales with the size of the array. Your method gives
the same result, but requires the programmer to do more work
rather than letting the compiler do it for him. Now you have to
change dts_length everytime data_to_send is changed in length.
