Abstract
One embodiment may take the form of a method and apparatus for remotely providing firmware to a wireless device. The wireless device may be configured to detect when the device's firmware is corrupted or may need updating. The device may then transmit a request for a firmware image on a first wireless communication channel. If the request is answered by an updating device, the wireless device may establish a communication with, and begin receiving the firmware image from, the updating device. Further, the wireless device may verify transmitted data and send an acknowledgment message to the updating device for each transmitted data packet.
