connection_request
Send a connection request to wake a CPE device without waiting for its periodic inform. Use this tool when you need the device to contact the ACS immediately, for example to execute pending tasks, apply preset changes, or force a parameter refresh. This sends an HTTP connection request to the CPE's management URL as configured in the TR-069 connection request mechanism. Returns 200 on success (the CPE acknowledged the request) or 504 if the CPE is unreachable (behind NAT, offline, or firewall blocking the connection request port). Example: connection_request(device_id="00236A-SmartRG585-SMRT00236a42"). Limitations: the CPE must be network-reachable from the ACS for connection requests to work. Devices behind NAT without STUN/NAT traversal configured will not respond. This does not queue a task — it only triggers the CPE to initiate a CWMP session.
