Use this constructor if pin definitions are provided manually.

The pins that are marked NC are optional. It is assumed that these pins are not connected until/unless configured otherwise.

Note: Pin ant_switch is equivalent to RxTx pin at https://developer.mbed.org/components/SX1276MB1xAS/. Reading the state of this pin indicates if the radio module type is SX1276MB1LAS(North American frequency band supported) or SX1276MAS (European frequency band supported). Pin dio4 can be mapped to multiple pins on the board, please refer to schematic of your board. For reference look at https://developer.mbed.org/components/SX1276MB1xAS/

Most of the radio module control pins are not being used at the moment as the SX1276MB1xAS shield has not connected them. For consistency and future use we are leaving the pins in the constructor. For example, if in some setting SX1276 radio module gets connected to an external power amplifier or radio latch controls are connected.

Destructor.

Check if the given RF is in range.

Parameters

frequency

frequency needed to be checked

Implements LoRaRadio.

Get radio status.

Parameters

status

Radio status [RF_IDLE, RF_RX_RUNNING, RF_TX_RUNNING]

Returns

Return current radio status

Implements LoRaRadio.

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

Parameters

events

Structure containing the driver callback functions

Implements LoRaRadio.

Acquire exclusive access.

Implements LoRaRadio.

Perform carrier sensing.

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

Parameters

modem	Type of the radio modem
freq	Carrier frequency
rssi_threshold	Threshold value of RSSI
max_carrier_sense_time	time to sense the channel

Returns

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

Implements LoRaRadio.

Resets the radio module.

Implements LoRaRadio.

Generates a 32 bits random value based on the RSSI readings.

Remark 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

32 bits random value

Implements LoRaRadio.

For backwards compatibility.
