# on Received String

Run part of a program when the @boardname@ receives a [string](/types/string) over ``radio``.

```sig
radio.onReceivedString(function (receivedString) {})
```

## Parameters

* **receivedString**: The [string](/types/string) that was sent in this packet or the empty string if this packet did not contain a string. See [send string](/reference/radio/send-string) and [send value](/reference/radio/send-value)

## ~ hint

Watch this video to see how the radio hardware works on the @boardname@:

## #example

## Troubleshooting

The ``||radio:on received string||`` event can only be created once, due to the hardware restrictions.

The radio set group might need to be set, synchronized, before the radio events will function.
