Zigbee endpoint logger
The Zigbee endpoint logger library provides the
You can use this endpoint handler function for parsing incoming ZCL frames and logging their fields and command payload.
The library can work as a partial replacement of nRF Sniffer for 802.15.4 for debugging and testing purposes. Unlike the sniffer, it provides logging information only for incoming ZCL frames on a specific device.
When you enable the library and register the handler at an endpoint, ZCL frames directed to this endpoint are intercepted and the registered handler is called. At that point, the handler counts and parses each frame: ZCL header is read and the payload of the command is obtained.
By default, the handler returns
ZB_TRUE when the frame has been processed or
ZB_FALSE if the stack must process the frame (as described in the ZBOSS API documentation).
This endpoint logger, however, only reads the incoming frame, but does not process the command, and so it always returns
After parsing and gathering the data, the “Received ZCL command” packet entry is added to the log. This entry has the following fields:
Source address (
Source endpoint (
Destination endpoint (
Cluster ID (
Profile ID (
Command direction (
cmd_dir), with one of the following values:
0if from client to server
1if from server to client
Common command (
common_cmd), with one of the following values:
0if the command is local or specific to a cluster
1if the command is global for all clusters
Command ID (
Transaction sequence number (
Disable default response (
disable_def_resp), with one of the following values:
0if the default response command is to be returned
1if the default response is to be disabled and the command is not to be returned
Manufacturer specific data (
voidif no data is present)
Payload of the command (
The parentheses after the entry name and at the end of the entry indicate the packet counter.

To enable the Zigbee endpoint logger library, set the
CONFIG_ZIGBEE_LOGGER_EP Kconfig option.
To configure the logging level of the library, use the
CONFIG_ZIGBEE_LOGGER_EP_LOG_LEVEL Kconfig option.
For detailed steps about configuring the library in a Zigbee sample or application, see Configuring Zigbee endpoint logger.

Library for logging incoming ZCL packets.
Provides Zigbee endpoint handler for parsing incoming ZCL packets and logging packet’s fields and payload.
zb_uint8_t zigbee_logger_eprxzcl_ep_handler(zb_bufid_t bufid)
Handler function which may be called to log an incoming frame onto Zigbee endpoint.
When this function is called as a callback bound to endpoint via ZB_AF_SET_ENDPOINT_HANDLER(), (directly or indirectly) it produces a log line similar to the following:
Received ZCL command (17): src_addr=0x0000(short) src_ep=64 dst_ep=64 cluster_id=0x0000 profile_id=0x0104 rssi=0 cmd_dir=0 common_cmd=1 cmd_id=0x00 cmd_seq=128 disable_def_resp=0 manuf_code=void payload= (17)
bufid – Reference to Zigbee buffer holding received zcl command to be logged
- Return values
ZB_FALSE – in all conditions. This enables possibility to use this function directly as Zigbee stack endpoint handler.
