as central devices and cannot communicate with each other ). Once the mobile phone is connected to the Activity Tracker, they can transmit GATT media data to each other. Based on the data they transmit, one party must assume the role of the server. For example, if an Activity Tracker wants to send sensor data to a mobile phone, the Activity Tracker must assume a server role. If the Activity Tracker wants to receive data from the mobile phone, the mobile phone must assume the role of the server.
