A Sockets API for LoRa
summary
Proposes a concrete Linux-side solution: a Linux socket family plus drivers (spi and serdev) and a netlink attributes API to set frequency, spreading factor, bandwidth and channel so user sockets carry radio parameters as addresses. Implements drivers for SX1272/76 and SX126x and partial support for SX130x concentrators, with SX127x/SX130x tested on single-board hardware; the transmit path implemented works, but multi‑channel reception coordination, USB/tty discovery and full LoRaWAN integration remain unresolved. Vendors (Laird) and BSD firmware aid development.
