Zigbee Error Codes in the Log

When debug logging is enabled the following error codes might be shown when problems occure.

0xE1 MAC channel access failure

Indicates interference issues when displayed very often. It is issued when a message couldn't be send due the medium (air) is too busy, the radio uses a listen-before-talk mechanism before sending out any message.

Causes:

• Using a ConBee II without an USB extension cable.
• USB 3.0 interference, using a USB 3.0 disk near to a ConBee II. This has a dramatic effect to 2.4 GHz radios when in close proximity. See Intel’s white paper.
• Interference with on board antennas close to the Raspbee II. In this case disabling of WiFi and Bluetooth is highly recomended (see https://www.raspberrypi.com/documentation/computers/config_txt.html using the overlay_prefix disable-wifi and disable-bt).
• Overlapping Zigbee and WiFi channels. Learn more about it in Zigbee and WiFi interference

0xE9 No MAC ACK received

Is issued when the coordinator sends out a command but no acknowledgement (ACK) was returned from the target receivers next hop (1-hop only).

0xA7 No application ACK received

Is similar to 0xE9 but works over a complete route.

0xD0 No route to the receiver exists

This appears usually when the receiver is powered off and is issued after a series of 0xE9 or 0xA7 codes. Note that routing is figured out and repaired automatically by all routing device.

0xD2 Zigbee broadcast table is full

This appears when too many broadcasts/group casts are send in fast succession.

0xF0 MAC transaction timeout

When a router/coordinator stores a message forwarded to a sleeping device and the device doesn't poll the parent within ca. 7 seconds, the message is discarded
