[SOLVED] Cannot change SRF08 address

hello,
i trying work several srf08 sensors (on arduino uno), in order so, have change addresses... but, although follow data-sheet's instructions, can't that.
here code :

code: [select]

 wire.begin();
 wire.begintransmission(old_address);
 wire.send(0);
 wire.send(0xa0);
 wire.endtransmission();
 
 wire.begintransmission(old_address);
 wire.send(0);
 wire.send(0xaa);
 wire.endtransmission();
 
 wire.begintransmission(old_address);
 wire.send(0);
 wire.send(0xa5);
 wire.endtransmission();
 
 wire.begintransmission(old_address);
 wire.send(0);
 wire.send(new_address);
 wire.endtransmission();

i don't know do, hope able help. in advance.
