uCentral Client

uCentral Client application for OpenWiFi access points, communicating with the uCentral Gateway.

This software is a part of the OpenWiFi AP NOS.

Developer Notes

The uCentral connection uses the WebSocket protocol, and messages are transferred in JSON-RPC format. Full details of this protocol can be found in a separate document here.

  • Incoming JSON-RPC messages are handled in proto.c:proto_handle().
  • Complex actions are executed via task queues (libubox/runqueue.h).
  • Many actions will fork external programs, notably ucode scripts installed by the ucentral-schema package (see ucentral-schema/command/).

This application registers several ubus methods under the ucentral object, as defined in ubus.c:ubus_object.
