I spent almost a month because of this problem.
I just wanted to draw a ZigBee map with recently purchased xStick USB in my house and I'm using Tuya Zigbee hub and some terminal devices such as lamp, light and some switches.
I have an xStick and it is connected my desktop through USB serial port COM9.
At first it was set as Baudrate was 9600, Data Bits 7, Parity none, Stop bits 1, Flow control none.
When I ran the program I can detect xStick in XCTU program and set port parameters as above but failed in drawing of ZigBee map because "Error discovering neighbors of 0013A....". I could see there is no C or R, etc on big icon in the left windows.
After many trial I could see ZigBee icon changed to "R" as router and could draw ZigBee map once in a short time and then lost again.
I formatted my computer and installed XCTU. The xStick is now changed to COM4 and I can detect xStick only in the setting of Baudrate 115200, Data Bits 8, Parity none, Stop bits 1, Flow control none. But I can't proceed further because I have error popup as "Error discovering neighbors of 0013A...." again.
How can I make correct setting and draw ZigBee map again?
