lirc_device — a special character device file; created to work with the RFM69 bitstream (receive/transmit); the default value is /dev/lirc0. Does not require changes.
rfm_irq — the number of interrupts from the RFM69 chip. Does not require changes.
rssi — rssi — maximum sensitivity of receiver in dBi (the bigger the modulo is negative the value, the higher the sensitivity is, maximum: -120). This option can be used to limit the reception of remote weak signals from unnecessary radio equipment.
spi_device — is a special device file for communication over the SPI-bus of the controller microprocessor. Depends on the hardware model of the controller. Wiren Board 5 uses /dev/spidev32766.0 — the bus is 32766, the chipselect is 0.
