Length
Frame Data
0x7E
Data bytes that need to be escaped:
Note: In the above example, the length of the raw data (excluding the checksum) is 0x0002 and
the checksum of the non-escaped data (excluding frame delimiter and length) is calculated as:
0xFF - (0x23 + 0x11) = (0xFF - 0x34) = 0xCB.
The length field has two-byte value that specifies the number of bytes that will be contained in the
frame data field. It does not include the checksum field.
Frame data of the UART data frame forms an API-specific structure as follows:
Figure 6‐03. UART Data Frame & API‐specific Structure:
The cmdID frame (API-identifier) indicates which API messages will be contained in the cmdData
frame (Identifier-specific data). Note that multi-byte values are sent big endian.The XBee ZNet 2.5
modules support the following API frames:

• 0x7E – Frame Delimiter
• 0x7D – Escape
• 0x11 – XON
• 0x13 – XOFF
Example - Raw UART Data Frame (before escaping interfering bytes):
0x11 needs to be escaped which results in the following frame:
0x7E 0x00 0x02 0x23 0x7D 0x31 0xCB
0x7E 0x00 0x02 0x23 0x11 0xCB
