LoRaRadio Class Reference
[stack layer that controls MAC layer underneath]

Checks whether the given RF is in range.

Parameters:

frequency

The frequency to check.

Gets the radio status.

Returns:

The current radio status.

Registers radio events with the Mbed LoRaWAN stack and undergoes initialization steps, if any.

Parameters:

events

Contains driver callback functions.

Acquires exclusive access to this radio.

Performs carrier sensing.

Checks for a certain time if the RSSI is above a given threshold. This threshold determines whether or not there is a transmission on the channel already.

Parameters:

modem	The type of radio modem.
freq	The carrier frequency.
rssi_threshold	The threshold value of RSSI.
max_carrier_sense_time	The time set for sensing the channel (ms).

Returns:

True if there is no active transmission in the channel, otherwise false.

Resets the radio module.

Generates a 32 bit random value based on RSSI readings.

Remarks:

This function sets the radio in LoRa modem mode and disables all interrupts. After calling this function, either `Radio.SetRxConfig` or `Radio.SetTxConfig` functions must be called.

Returns:

A 32 bit random value.

Sets the radio to reception mode.

To configure the receiver, use the `set_rx_config()` API.

Sends the packet.

Prepares the packet to be sent and sets the radio to transmission mode.

Parameters:

buffer	A pointer to the buffer.
size	The buffer size.

Sets the carrier frequency.

Parameters:

freq	Channel RF frequency.

Sets the maximum payload length.

Parameters:

modem	The radio modem [0: FSK, 1: LoRa].
max	The maximum payload length in bytes.

Sets the network to public or private.

Updates the sync byte. Applies to LoRa modem only.

Parameters:

enable

If true, enables a public network.

Sets reception parameters.

Sets the transmission parameters.
