Start bluetoothctl and pair an Android phone<\/h2>\n

In this particular example, we use an Android phone to pair with your\u00a0mLinux\u2122\u00a0<\/sup>device. Of course, you can use\u00a0other bluetooth-enabled devices for pairing.<\/p>\n

Using bluetoothctl on the device
\n<\/a><\/h3>\n
$ sudo bluetoothctl\r\n[bluetooth] power on\r\n[bluetooth] discoverable on\r\n[bluetooth] pairable on\r\n[bluetooth] agent KeyboardOnly\r\n[bluetooth] default-agent<\/pre>\n
Enter the following command to show services:<\/p>\n
[bluetooth]show<\/pre>\n
Now the system lists the services on the device.<\/p>\n

Initial setup of phone<\/h3>\n
    \n
  1. Go into the bluetooth menu of your phone and this should make your phone discoverable.<\/li>\n
  2. Turn scan on the device. You should see the name of the device that was entered in main.conf (assuming you made the device discoverable).<\/li>\n<\/ol>\n
    Scan and trust on device<\/h3>\n
    scan on<\/pre>\n
    Wait until you see the following message (for your device):<\/p>\n
    [NEW] Device DC:74:A8:05:39:77 Test Cell Phone<\/pre>\n
    Now turn scan off and trust the device:<\/p>\n
    [bluetooth] scan off\r\nDiscovery stopped\r\n[bluetooth] trust DC:74:A8:05:39:77\r\n[CHG] Device DC:74:A8:05:39:77 Trusted: yes\r\nChanging DC:74:A8:05:39:77 trust succeeded<\/pre>\n
    Pairing from mLinux device<\/h3>\n
    This operation must be done rapidly due to timeouts on pairing. The pairing must immediately be accepted from the phone. Now pair the device (note the passkey number):<\/p>\n

    If you have not done discovery for a while, or if the phone is not discoverable, you may see this response:<\/p>\n
    Device DC:74:A8:05:39:77 not available<\/pre>\n
    Response example on an Android Phone<\/h3>\n
    You should see the same passkey number from the mLinux output displayed on the Android phone (the other connecting device in this example).<\/p>\n
    Quickly confirm the passkey number to accept the request on the phone OS.<\/p>\n
    If done in time, you should now see the device listed under Paired\u00a0Devices (or Bluetooth > My Devices if using iOS)\u00a0 in the phone OS.<\/p>\n","protected":false},"excerpt":{"rendered":"
