AT Command Access

To gain AT command access through the 6350-SR, the tester must have a PC/laptop connected to one of the LAN Ethernet ports of the 6350-SR. They should receive an IP address via DHCP from the 6350-SR in the 192.168.0.100-250 range. If they do not receive a DHCP address, they can configure a static IP on the PC/laptop of 192.168.0.2/24 with a gateway of 192.168.0.1

  • Open a SSH session to the 6350-SR. Default login credentials are:
    • username: root
    • password: default
  • Select a to access the Admin CLI. If the SSH session immediately gives you the # prompt, you are already in the Admin CLI.
  • Type atcmd and press Enter. Type n when the SR prompts you if you want exclusive access. This allows you to send AT commands to the device while still allowing the device to connect, disconnect, and/or reconnect to the Sprint network.
  • Example AT command access below:
$ ssh [email protected]
Password:

Access selection menu:

a: Admin CLI
s: Shell
q: Quit
