Wear OS (also known simply as Wear[8] and formerly Android Wear[9]) is a version of Google's Android operating system designed for smartwatches and other wearables.[10][11][12] By pairing with mobile phones running Android version 6.0 "Marshmallow" or newer, or iOS version 10.0 or newer with limited support from Google's pairing application,[13] Wear OS integrates Google Assistant[14] technology and mobile notifications into a smartwatch form factor. Wear OS is closed-source, in contrast to the free and open-source Android.[2][3]
Wear OS supports Bluetooth, NFC, Wi-Fi,[15] 3G, and LTE connectivity, as well as a range of features and applications. Watch face styles include round, square and rectangular. Hardware manufacturing partners include Asus, Broadcom, Fossil, HTC, Intel, LG, MediaTek, Imagination Technologies, Motorola, New Balance, Xiaomi, Qualcomm, Samsung, Huawei, Skagen, Polar, TAG Heuer, Suunto, and Mobvoi.[16]
Canalys estimates that over 720,000 Android Wear smartwatches were shipped in 2014, the year of its launch.[17] By mid-October 2022, the Wear OS app had more than 50 million downloads.[18] Wear OS was estimated to account for 17.3% of the smartwatch market in Q3 2021, behind Apple's 21.8%. Samsung accounts for the majority of Wear OS devices sold,[19] due to its switch back from Tizen to Wear OS in 2021.[20]

The proprietary nature of Wear OS makes it even harder to gain deep visibility into the wearable networking stack. Note that unlike Android for handheld devices, Wear OS is not open-source.

Since Wear OS is closed source, we cannot modify the framework so we implement a Proof-Of-Concept (POC) solution.
