under Ubuntu, you can use Gtkterm Serial port is 38400,8N1 flow control: none the last byte is the LSB of sum of all the previous 6 bytes eg, FC(hex) + 00(hex) + 91(hex) + 03(hex) + A3(hex) + B3(hex) = 2E6(hex), so the LSB of 2E6(hex) is E6 (hex) Read PAN ID: FC 00 91 03 A3 B3 E6 Read Short Address: FC 00 91 04 C4 D4 29 Read MAC Address: FC 00 91 A8 B8 F5 Read the type of node: FC 00 91 0B CB EB 4E return: 43 6F 6F 72 64 69 means coordinator return: 52 6F 75 74 65 72 means router Read the wireless channel no: FC 00 91 0D 34 2B F9
