To perform Bluetooth FTP functions, you must first complete the steps in the following procedure.

​
Prerequisites

  • Enable SSH to access your host device. For instructions, see Sign in using SSH.
  • Ensure that the DUT and the remote device support the BlueZ stack. One device acts as a server and another device acts as a client.
    To test or verify FTP server functions, a test application isn’t required. Perform FTP functions through the client connection.
  • Pair the DUT and the remote device. For instructions, see Pair with a remote Bluetooth device.
  • Place the DUT and the remote device in the Bluetooth vicinity.

​
Set up the device for Bluetooth FTP functions

  1. Run the SSH in command prompt using the following command: 
    ssh root@<device_IP_address>
    Example If the IP address of the device is 10.92.160.222, run the following command: 
    ssh root@10.92.160.222
  2. Connect to the SSH by entering the following password: 
    oelinux123
  3. Open the Bluetooth test application by running the following command: 
    obexctl
    To view OBEX functions, run the following command: 
    help
    This command provides the main menu of obexctl. Sample output 
    sh-5.1# obexctl
[NEW] Client /org/bluez/obex
[obex]# help

  4. Connect to the remote device by running the following command from the obexctl menu: 
    connect <bt_address> <profile_name>
    Parameters
    • <bt_address> is the Bluetooth address of the remote device.
    • <profile_name> is ftp.
    Example To connect to a remote device with <bt_address> E8:48:B8:C8:20:00, run the following command: 
    connect E8:48:B8:C8:20:00 ftp
    Sample output 
    [E8:48:B8:C8:20:00]# connect E8:48:B8:C8:20:00 ftp

Perform Bluetooth FTP client functions

You can verify Bluetooth FTP client functionality using the commands provided in the main menu of obexctl. Bluetooth FTP client functions include creating a new folder and changing the current folder to navigate the file system. You can retrieve information about the current folder, copy a file to a remote device, copy a file from a remote device, copy a file within the remote device, move files between locations and delete files when they are no longer required using the FTP client functions.
