Example of XBee API frames
Some examples of XBee API Frames. Modem status frame 7E 00 02 8A 06 6F 7E : API Frame 00 02 : Length 8A : Modem status 06 : Coordinator started 6F : checksum FF – ((8A +06) & FF) = 6F AT Command API Frame: MY 7e 00 04 08 52 4D 59 FF 7E : API Frame 00 02 : Length 08 : AT Command Frame id 52 : Frame id 4d 59 : MY (4d 59) (4d ⇒ M, 59 ⇒ Y) Get the 16-bit network address of the module.
