Hello, I am learning ZigBee with JN5189. I downloaded SDK_2.6.0_JN5189DK6, and fully follow the SDK_2.6.0_JN5189DK6\docs\wireless\ZigBee\ZigBee Demo Applications User’s Guide using it. But when I tried the Coordinator Application demo, I send commands to the port but there is no response, and the dongle can't sniff any network. The Baudrate, port and other settings are as same as the manual, but the result is completely different from that in the manual. Could you please tell me a solution? I'm totally new to this and I really have no idea what to do.
