Description

After flashing the example Zigbee_On_Off_Light.ino sketch to the device, it appears to initialize Zigbee, then almost immediately fails with Network steering was not successful. I expected it to connect to my open Sonoff Zigbee dongle, which I successfully detected (after like 5-10 seconds) with the Zigbee_Scan_Networks.ino sketch:

[  7994][V][ZigbeeCore.cpp:367] scanCompleteCallback(): Network 0: PAN ID: 0x2ac8, Permit Joining: Yes, Extended PAN ID: db:94:6e:a1:2d:85:41:56, Channel: 11, Router Capacity: Yes, End Device Capacity: Yes

Normally, Zigbee devices connect automatically to it, so I'm not sure why this one won't.

/**
 * @brief This example demonstrates simple Zigbee light bulb.
 *
 * The example demonstrates how to use Zigbee library to create a end device light bulb.
 * The light bulb is a Zigbee end device, which is controlled by a Zigbee coordinator.
 *
 * Proper Zigbee mode must be selected in Tools->Zigbee mode
 * and also the correct partition scheme must be selected in Tools->Partition Scheme.
 *
 * Please check the README.md for instructions and more detailed description.

Other Steps to Reproduce

Running on board version 3.1.1, but it wasn't in the versions drop-down. The only modification I made to the sketch was changing RBG_BUILTIN to LED_BUILTIN.

I have checked existing issues, online documentation and the Troubleshooting Guide

Hi @alecthegeek, I am also using the SonOff Zigbee dongle without any issues. Can you please select to use the debug zigbee libs in the Tools menu - Zigbee mode: Zigbee ED (end Device) - Debug and post a full log again?

From what I remember on other issues, the seedstudio may have a poor antenna. We will see from logs :)
