Expand description
What an SX127x reports back in LoRa mode: the signal levels of a packet and the modem’s state.
The levels follow the RSSI and SNR in LoRa Mode section of the SX1276/77/78/79
datasheet (Rev 7) and its descriptions of RegPktSnrValue, RegPktRssiValue, and
RegRssiValue. The chip reports power in whole decibels above an offset that depends on
which of its two RF ports is in use, and SNR in quarters of a decibel, so every level
comes out as a [Decibels] with nothing rounded away.
Structs§
- Modem
Status - The live state of the LoRa modem, from RegModemStat.
- Packet
Status - The signal levels of the last LoRa packet received.
Enums§
- Port
- The RF port a frequency is received on, which sets the RSSI offset.
Constants§
- MID_
BAND_ HZ - The frequency, in hertz, above which a radio uses its high frequency port. It is the threshold Semtech’s LoRaMac-node applies to the SX1276’s RSSI offsets and errata.
Functions§
- rssi_
dbm - Decodes RegRssiValue, the signal power the receiver hears right now.
