FAQs:
General Configuration:
1) How can I discover all the other 2G boards on the same LAN?

Use the telnet or debug console to attach to the target board

Login as “root” and then change directory “cd usr/local/bin”

Start discover all: $./node_list

Start discover hosts: $./node_list -t host

Start discover clients: $./node_list -t client

The result will be shown on the console, where hosts are 2G Transmitters and clients are 2G Receivers
2) How do I read/write target board's UART port 1 (/dev/ttyS0)?

Use telnet or debug console to attach to target board

Use stty to configure the UART port 1. Ex: $stty 115200 -F /dev/ttyS0 => set UART port 1's baud rate to
115200.

To start read: $cat /dev/ttyS0 & => UART data will be redirected to console

To stop read: $pkill cat

To start write: $cat > /dev/ttyS0 => console input will be redirected to UART

To stop write: press "ctrl+c" (0x03)
3) What if I need to include
“ctrl+c (0c03) in my RS232 command string?

You can use the console function $printf instead to send commands out port 1 (/dev/ttyS0)

Example:
$ printf "\x02 PLAY \x03" > /dev/ttyS0
4) How do I configure UART port 1 (/dev/ttyS0) for non-"Serial over IP" usage?

UART port 1 is typically used for "Serial over IP" feature. Developers who want to manually control UART
port 1 need to disable the "Serial over IP" feature.

To configure UART port 1, please use "stty" command. See "Console APIs Description" below for details.
5) How do I change the IP Address and Netmask of the Transmitters or Receivers

