Abstract: A method for operating a mesh network is described. The method includes using a protocol comprising an address and a payload, wherein the address and payload are restricted. The method also includes using a hash function to generate an address from a description, wherein the description uses ASCII characters, wherein a message uses the description as an address and wherein the description is transformed into the address using the hash function and added together with the message into the payload, assigning the generated address to a device, wherein the device is part of a mesh network, and in a transmission from a source to the device, providing the generated address within the payload.

Abstract: A radio arbitrator, electronic system, and method for wireless communication are disclosed in which at least two RF requests are received through a single radio module. The radio arbitrator performs predictive arbitration based on timing information known for an RF request prior to receiving the RF request. Rf requests may be based on one or more of ZigBee, Bluetooth Low Energy, or WiFi communication topologies.
