Detailed Description

UDP socket-based IEEE 802.15.4 device over ZEP

ZigBee Encapsulation Protocol for protocol definitions

This ZEP implementation can send a dummy HELLO packet on startup. This is used to make dispatchers aware of the node. To enable this behavior, add

USEMODULE += socket_zep_hello

to your Makefile.

A ZEP dispatcher can just drop those packets (ZEP type 0xFF) if it chooses to parse the ZEP header.

The header of the HELLO packet will look like this:

Macro Definition Documentation

SOCKET_ZEP_MAX

#define SOCKET_ZEP_MAX   (1)

Number of allocated parameters at socket_zep_params.

Note

This was decided to only be confiruable on compile-time to be more similar to actual boards

Definition at line 35 of file socket_zep_params.h.

Enumeration Type Documentation

zepdev_state_t

enum zepdev_state_t

ZEP device RX state.

Enumerator
ZEPDEV_STATE_IDLE	ZEP is not doing anything, not receiving frames.
ZEPDEV_STATE_RX_ON	ZEP is able to receive frames.
ZEPDEV_STATE_RX_RECV	unprocessed frame is in RX buffer, rx stopped
ZEPDEV_STATE_TX	ZEP is currently sending a frame.
