# Connection
## Selection
If exactly one device is connected (i.e. listed by `adb devices`), then it is
automatically selected.
However, if there are multiple devices connected, you must specify the one to
use in one of 4 ways:
- by its serial:
```bash
scrcpy --serial=0123456789abcdef
scrcpy -s 0123456789abcdef # short version
# the serial is the ip:port if connected over TCP/IP (same behavior as adb)
scrcpy --serial=192.168.1.1:5555
```
- the one connected over USB (if there is exactly one):
```bash
scrcpy --select-usb
scrcpy -d # short version
```
- the one connected over TCP/IP (if there is exactly one):
```bash
scrcpy --select-tcpip
scrcpy -e # short version
```
- a device already listening on TCP/IP (see [below](#tcpip-wireless)):
```bash
scrcpy --tcpip=192.168.1.1:5555
scrcpy --tcpip=192.168.1.1 # default port is 5555
```
The serial may also be provided via the environment variable `ANDROID_SERIAL`
(also used by `adb`):
```bash
# in bash
export ANDROID_SERIAL=0123456789abcdef
scrcpy
```
```cmd
:: in cmd
set ANDROID_SERIAL=0123456789abcdef
scrcpy
```
```powershell
# in PowerShell
$env:ANDROID_SERIAL = '0123456789abcdef'
scrcpy
```
## TCP/IP (wireless)
_Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a
device over TCP/IP. The device must be connected on the same network as the
computer.
[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
### Automatic
An option `--tcpip` allows to configure the connection automatically. There are
two variants.
If the device (accessible at 192.168.1.1 in this example) already listens on a
port (typically 5555) for incoming _adb_ connections, then run:
```bash
scrcpy --tcpip=192.168.1.1 # default port is 5555
scrcpy --tcpip=192.168.1.1:5555
```
If _adb_ TCP/IP mode is disabled on the device (or if you don't know the IP
address), connect the device over USB, then run:
```bash
scrcpy --tcpip # without arguments
```
It will automatically find the device IP address and adb port, enable TCP/IP
mode if necessary, then connect to the device before starting.
### Manual
Alternatively, it is possible to enable the TCP/IP connection manually using
`adb`:
1. Plug the device into a USB port on your computer.
2. Connect the device to the same Wi-Fi network as your computer.
3. Get your device IP address, in Settings → About phone → Status, or by
executing this command:
```bash
adb shell ip route | awk '{print $9}'
```
4. Enable `adb` over TCP/IP on your device: `adb tcpip 5555`.
5. Unplug your device.
6. Connect to your device: `adb connect DEVICE_IP:5555` _(replace `DEVICE_IP`
with the device IP address you found)_.
7. Run `scrcpy` as usual.
8. Run `adb disconnect` once you're done.
Since Android 11, a [wireless debugging option][adb-wireless] allows to bypass
having to physically connect your device directly to your computer.

## Autostart
A small tool (by the scrcpy author) allows to run arbitrary commands whenever a
new Android device is connected: [AutoAdb]. It can be used to start scrcpy:
```bash
autoadb scrcpy -s '{}'
```
