# Perform Bluetooth HFP client functions

You can perform HFP client functions using the `bluetoothctl` menu and `ofono/test` tools. Bluetooth HFP client functions include connecting or disconnecting to a remote device and managing phone calls over Bluetooth. You can dial a phone number, answer or reject incoming calls, and list active calls using HFP client functions.

## Prerequisites

Before you begin, [set up your device](https://docs.qualcomm.com/doc/80-70030-13/topic/bluez-hfp.html#section-rmp-dgv-mcc-08-25-24-1227-32-765) and [configure the DUT for HFP client functions](https://docs.qualcomm.com/doc/80-70030-13/topic/bluez-hfp.html#section-nlh-q3v-mcc-08-25-24-1246-29-767).

## Connect a remote device

To connect a remote device, run the following command from the `bluetoothctl` menu:

connect <bt_address>
    Copy to clipboard

**Parameters**

`<bt_address>` is the Bluetooth address of the remote device.

**Example**

To connect to a paired remote device with `<bt_address>` `F8:7D:76:9D:9B:6B`, run the following command:

connect F8:7D:76:9D:9B:6B
    Copy to clipboard

**Sample output**

[bluetooth]# connect F8:7D:76:9D:9B:6B
