XBee/XBee-PRO® S2C ZigBee® RF Module

208

Frame data fields Offset Description

Transmission options 22

All bits must be set to 0.

Data payload 23

The required payload for a ZDO command. All multi-byte ZDO

parameter values (u16, u32, 64- bit address) must be sent in little

endian byte order.

The Active Endpoints Request includes the following payload:

[16-bit NwkAddrOfInterest]

Note The 16-bit address in the API example (0x1234) is sent in little

endian byte order (0x3412).

Example

The following example shows how you can use the Explicit API frame to send an “Active Endpoints”

request to discover the active endpoints on a device with a 16-bit address of 0x1234.
