Abstract
A replaceable wearable band includes an embedded protocol bridge module that enables certified smartphone communication for a wearable core device. The band carries a wired interface that provides power and data between the wearable core device and the protocol bridge module. The protocol bridge module includes an authentication coprocessor and a dual-mode Bluetooth system-on-chip and translates between a wired-device protocol and a certified accessory communication protocol carried over Bluetooth Classic to a smartphone. The wearable core device interacts with the protocol bridge module as a wired peripheral without implementing the certified accessory protocol. In some embodiments, the protocol bridge module is positioned near a clasp or buckle to increase distance from sensitive EMG electrodes and analog front ends, and transmissions may be scheduled to avoid EMG acquisition windows. The band may be swapped to retrofit certified communication across device generations without modifying the wearable core device hardware.
