Dear Aprilbro,  
I set uuid by command “AT+PUID=FFFF **000A000A000A** 09101112131415”, and get back from CC2540 with the content is “OK+Set:FFFF **000A000A000A** 09101112131415” which is the same with uuid I just set.  
However , when send command “AT+PUID?” ,I get the reply with the different uuid “FFFF **002A002A002A** 09101112131415” .  
Why would this happen? Is there anything wrong with the command?
