Detailed Description

LoRaWAN downlink callback parameters.

Field Documentation

cb

void(* lorawan_downlink_cb::cb) (uint8_t port, uint8_t flags, int16_t rssi, int8_t snr, uint8_t len, const uint8_t *data)

Callback function to run on downlink data.

Note

Callbacks are run on the system workqueue, and should therefore be as short as possible.

Parameters

port	Port message was sent on
flags	Downlink data flags (see lorawan_dl_flags)
rssi	Received signal strength in dBm
snr	Signal to Noise ratio in dBm
len	Length of data received, will be 0 for ACKs
data	Data received, will be NULL for ACKs

node

sys_snode_t lorawan_downlink_cb::node

Node for callback list.

port

uint16_t lorawan_downlink_cb::port

Port to handle messages for.

• Port 0: TX packet acknowledgements
• Ports 1-255: Standard downlink port
• LW_RECV_PORT_ANY: All downlinks
