## Callback Parameters
|
|
|
|
* ``packet`` - the [packet](/reference/radio/packet) that was received by the radio. The packet has the following properties:
|
|
* `receivedNumber` - The [number](/types/number) that was sent in this packet or `0` if this packet did not contain a number. See [send number](/reference/radio/send-number) and [send value](/reference/radio/send-value)
|
|
* `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)
|
|
* `time` - The system time of the @boardname@ that sent this packet at the time the packet was sent.
|
|
* `serial` - The serial number of the @boardname@ that sent this packet or `0` if the @boardname@ did not include its serial number.
|
|
* `signal` - How strong the radio signal is from `-128` (weak) to `-42` (strong).
|
|
|
|
## Troubleshooting
|
|
|
|
The on radio data 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.
