# How can I know that 2 x-bee are paired before or not?

I got 2 x-bee from my school lab, and I want to use it. These 2 x-bee are paired before or not, how can I check it? What should I do to know whether it is paired or not?

• Welcome to EE.SE! You need to be more descriptive in your question about your situation (click the edit button). What model X-Bee devices do you have? What interface will you use with the devices? Also, have you contacted the lab admin for documentation or instructions on these devices? – user2943160 Jul 10 '16 at 4:30
