Module status 

Device status and interrupts

The device status is represented by two bytes provided on each command. It contains:

• Information about previous command (Ok, fail, error, …)
• A flag for interrupt pending
• The source of the last reset (manual, analog, watchdog, …)
• Current chip Mode (Sleep, Standby, Tx, RX, …)

The interrupt structure Intr allows to both configrue which interrupt should be assigned to a pin with the command set_dio_irq and easily get which interrupt is currently raised after a get_status or get_and_clear_irq.

Constants

IRQ_MASK_ADDR_ERROR

IRq raised if the packet was received with a wrong address match

IRQ_MASK_CAD_DETECTED

Channel activity detected

IRQ_MASK_CAD_DONE

Channel activity detection finished

IRQ_MASK_CMD

There was a host command fail/error

IRQ_MASK_CRC_ERROR

IRq raised if the packet was received with a wrong CRC

IRQ_MASK_EOL

End of life

IRQ_MASK_ERROR

An error other than a command error occurred (See GetErrors)

IRQ_MASK_FHSS

IRQ after each ramp-up for intra-packet hopping

IRQ_MASK_FSK_TXRX

Mask to enable all interrupt usefull for FSK TX/RX (preamble detected, tx/rx done, timeout, CRC/Length error)

IRQ_MASK_HEADER_ERR

LoRa header CRC error

IRQ_MASK_HEADER_VALID

LoRa header detected / Valid sync word

IRQ_MASK_INTER_PACKET1

Host can load new frequencies table

IRQ_MASK_INTER_PACKET2

Host can load new payload

IRQ_MASK_LEN_ERROR

IRq raised if the packet was received with a length error

IRQ_MASK_LORA_HDR_TIMESTAMP

LoRa header precise timestamp (explicit mode). In implicit mode will assert after 8 symbols of the payload.

IRQ_MASK_LORA_SYMBOL_END

End of LoRa symbol (for debug)

IRQ_MASK_LORA_TIMESTAMP_STAT

New statistics available in timestamp register (debug)

IRQ_MASK_LORA_TXRX

Mask to enable all interrupt usefull for LoRa TX/RX (preamble detected, header ok/err, tx/rx done, timeout, CRC error)

IRQ_MASK_LORA_TX_RX_HOP

IRq for LoRa intra-packet hopping

IRQ_MASK_PA

PA OCP/OVP was triggered

IRQ_MASK_PREAMBLE_DETECTED

Preamble detected

IRQ_MASK_RNG_EXCH_VLD

Master received a valid ranging response from the slave

IRQ_MASK_RNG_REQ_DIS

Ranging request discarded (no address match)

IRQ_MASK_RNG_REQ_VLD

Valid ranging request received (slave)

IRQ_MASK_RNG_RESP_DONE

Slave sent its ranging response

IRQ_MASK_RNG_TIMEOUT

Master did not receive a response from the slave

IRQ_MASK_RX_DONE

Packet received

IRQ_MASK_RX_FIFO

RX FIFO threshold reached

IRQ_MASK_RX_TIMESTAMP

IRq for time-stamping end of packet Rx, without dependent delay of demodulation or mode switching. Only to be used for timestamping, not for changing mode or re-configuring the device.

IRQ_MASK_SYNC_FAIL

Syncword match failed after detection (for debug)

IRQ_MASK_TIMEOUT

Rx or Tx timeout

IRQ_MASK_TX_DONE

Packet transmission completed

IRQ_MASK_TX_FIFO

TX FIFO threshold reached

IRQ_MASK_TX_TIMESTAMP

IRq for time-stamping end of packet Tx, without dependent delay of mode switching. Only to be used for timestamping, not for changing mode or re-configuring the device.
