Abstract
Methods and devices useful in performing magneto-inductive charging and communication in the absence of a cellular and/or internet network connection are provided. By way of example, an electronic device includes inductive charging and communication circuitry configured to receive a signal configured to induce a charging function based at least in part on an inductive coil coupled to the inductive charging and communication circuitry. Inducing the charging function includes charging an energy storage component of the electronic device. The inductive charging and communication circuitry is also configured receive an indication to switch from the charging function to a communication function. The communication function is based at least in part on the inductive coil. The inductive charging and communication circuitry is further configured establish a communication link between the electronic device using the inductive coil to transmit and receive communication signals.
