Detailed Description

Structure containing the configuration of a LoRa modem.

Field Documentation

◆ bandwidth

enum lora_signal_bandwidth lora_modem_config::bandwidth

The bandwidth to use for transceiving.

◆ [struct]

struct { ... } lora_modem_config::cad

Channel Activity Detection parameters.

◆ coding_rate

enum lora_coding_rate lora_modem_config::coding_rate

The coding rate to use for transceiving.

◆ datarate

enum lora_datarate lora_modem_config::datarate

The data-rate to use for transceiving.

◆ detection_minimum

uint8_t lora_modem_config::detection_minimum

Minimum detection threshold (hardware-specific, dimensionless).

Passed directly to the radio. 0 = auto-derive from SF/BW.

◆ detection_peak

uint8_t lora_modem_config::detection_peak

Detection peak threshold (hardware-specific, dimensionless).

Passed directly to the radio. 0 = auto-derive from SF/BW.

◆ frequency

uint32_t lora_modem_config::frequency

Frequency in Hz to use for transceiving.

◆ iq_inverted

bool lora_modem_config::iq_inverted

Invert the In-Phase and Quadrature (IQ) signals.

Normally this should be set to false. In advanced use-cases where a differentation is needed between "uplink" and "downlink" traffic, the IQ can be inverted to create two different channels on the same frequency

◆ mode

enum lora_cad_mode lora_modem_config::mode

CAD mode.

See lora_cad_mode for details.

◆ packet_crc_disable

bool lora_modem_config::packet_crc_disable

Set to true to disable the 16-bit payload CRC.

◆ preamble_len

uint16_t lora_modem_config::preamble_len

Length of the preamble.

◆ public_network

bool lora_modem_config::public_network

Sets the sync-byte to use:

false: for using the private network sync-byte
true: for using the public network sync-byte The public network sync-byte is only intended for advanced usage. Normally the private network sync-byte should be used for peer to peer communications and the LoRaWAN APIs should be used for interacting with a public network.

◆ symbol_num

enum lora_cad_symbol_num lora_modem_config::symbol_num

Number of symbols for CAD detection.

0 = driver default.

◆ tx

bool lora_modem_config::tx

Set to true for transmission, false for receiving.

◆ tx_power

int8_t lora_modem_config::tx_power

TX-power in dBm to use for transmission.
