SINGLE - SECONDARY COMMUNICATION

•  If the piconet has only one secondary , the TDMA operation is very simple . The time is divided into slots of 625 microseconds .
• The primary / master uses even - numbered slots (0,2,4,....); the secondary / slave uses odd - numbered slots  (1,3,5,.......) .
• TDD- TDMA allows the primary and secondary to communicate in half - duplex mode .
•  In slot 0 , the primary sends , and the secondary receivers; in slot 1 , the secondary sends, and the primary receives .
