Systems and methods for utilizing unused space in expensive message based communication to embed messages from a sender device to a receiver device to maximize payload usage over a potentially fee-based messaging service. One or more machine-to-machine messages may be embedded in unutilized transport space when other communications, that may potentially be delivered over a fee-based network, are initiated at a device. The machine-to-machine message and other communications may be extracted from a combined message package at a receiving device and processed as if they were independently transported. Machine-to-machine messages may be segmented and embedded across multiple unrelated communication packages and later reassembled.

Embedded communication in message based transports

Disclosed in some examples is a method for communications between a client and a server using a stateless messaging protocol by transmitting from a client to a server a first message using the stateless messaging protocol; receiving from the server a response message, the response message including an indication of the presence of a second message at the server intended for the client, the indication including message retrieval information; sending a third message from the client to the server including the message retrieval information; and receiving a fourth message from the server, the fourth message including the contents of the second message.

Enhanced HTTP messaging for devices

A networked firmware management system is operable to manage firmware in one or more target devices by receiving one or more firmware target specifications from one or more target devices, the firmware target specifications each identifying a firmware target in the target device. The server stores the one or more received firmware target specification, associated with the one or more firmware targets in the target device. When the server receives a firmware update, the server matches a firmware attribute of the received firmware update against the one or more firmware target specifications stored in the server, and sends the received firmware update to any firmware targets in the target device having a firmware target specification that matches the received firmware update attribute.

Remote firmware upgrade device mapping

A wireless mesh network server is operable to receive a message to one or more mesh network nodes from a client external to the mesh network, the message comprising an alias identifying the one or more mesh network nodes. The server is further operable to identify the one or more receiving mesh network nodes by the received message alias via an alias table, and forward the received message to the one or more mesh network nodes identified by the alias.

Mesh network bridge routing

Systems and methods for automatically provisioning devices that do not include or cannot provide a unique hardware identifier over a machine-to-machine network. A device or application may provide a server with a non-unique provisioning identifier during restricted communication between the server and the device. In response to receiving a provisioning identifier from a device, a server may generate a globally unique device identifier associated with the provisioning identifier for the individual device, and transmit the unique identifier to the device. The device may retain the unique identifier for future transactions. A request may be provided to a user, at the device, the server or any other interface, requesting that a newly identified device be authenticated. Upon authentication the device may communicate with the server with additional interactions that were not provided after provisioning and before authentication.
