SPP API — a short tour

A quick orientation to the C API. The full reference — every file, struct, function and macro — is under Files and Data Structures.

The application is deliberately tiny: it wires the ESP32-S3 HAL port into the finite state machine and then ticks it forever.

void app_main(void)
{
    const SPP_HalPort_t *p_halPorts = SPP_PORTS_ESP32S3_getHalPorts();
    (void)FSM_init((void *)p_halPorts);
    while (1) {
        FSM_tick();
    }
}

Everything else — sensor sampling, packet routing, logging, downlink — is driven from the FSM (fsm.h) through the publish/subscribe core (pubsub.h).
