Radio Block-List

Blocks	Description
	Make a program have the group ID you tell it for sending and receiving with radio.
	Broadcast a number to other micro:bits connected via radio.
	Send a string and number together by radio to other micro:bits. The maximum string length is 8 characters. name: a string that is the name of the value to send. value: a number that is the value to send.
	Sends a string to other micro:bits in the area connected by radio. The maximum string length is 19 characters. msg: a string to send by radio.
	Run part of a program when the micro:bit receives a number over radio. Received Number: The number that was sent in this packet or `0` if this packet did not contain a number. See send number and send value
	Run part of a program when the micro:bit receives a name-value-pair over radio. name: a string that is a name for the value received. value: a number that is the value received.
	Run part of a program when the micro:bit receives a string over . receivedstring: The string that was sent in this packet or the empty string if this packet did not contain a string. See send string and send value.
	Get one of the properties from the last received radio packet. type: the property type to get from the packet. These are: signal strength: the strength of the radio signal when the packet was received. serial number: the serial number of the board sending the packet. time: the time when the packet was sent.
	Make the `radio` signal of the micro:bit stronger or weaker. The signal can be as weak as `0` and as strong as `7`. Default is `6` If your micro:bit is sending with a strength of `7`, and you are in an open area without many other computers around, the micro:bit signal can reach as far as 70 meters (about 230 feet). `power` is a number between `0` and `7` that means how strong the signal is.
	Make the radio packet embed the board serial number with each packet of data. transmit: a boolean that, when `true`, means that the board serial number is included in each transmitted packet. If `false`, the serial number value is set to `0`.
	Change the transmission and reception band of the radio to the given channel. Default is 7. `band` is a number between `0` and `83`. Each step is 1MHz wide, based at 2400MHz.
	Sends an event over radio to be raised in the event bus of other micro:bit. This is an advanced API.
