Abstract
A method for updating firmware in a wireless charger is implemented when the wireless charger charges a chargeable device. A wireless link is established between the charger and the chargeable device for transferring energy from the charger to the chargeable device. The wireless link also is used to transfer a new version of a firmware program running on the charger, from the chargeable device to the charger. The wireless charger can detect interruption in reception of the new version of the firmware program and identify a breakpoint where the data transfer was interrupted. The wireless charger can resume reception of the firmware program from the breakpoint when the wireless link is re-established. The firmware update can be initiated by an app on the chargeable device.
