Inspect what sites have access to what devices and revoke these pairings. To the UA, the UA MUST assume they give the site complete control over theĭevice and inform the user of this risk. MUST inform the user what capabilities these services give the website beforeĪsking which devices to entrust to it. It gets the ability to access all GATT services mentioned in the call. When a website requests access to devices using requestDevice(), Services :, }] }).then (device => device. To discover and retrieve data from a standard heart rate monitor,Ī website would use code like the following:

It intends to also support communication among devices that only implement While this specification cites the specification, The first version of this specification allows web pages, running on a UA in the Central role, to connect to GATT Servers over either a BR/EDR or Transport, the GATT protocol can also run over BR/EDR transport. Devices acting in the Peripheral role can receiveĬonnections, and devices acting in the Central role can connect to Peripheral devices.Ī device acting in either the Peripheral or Central role can hostĪ GATT Server, which exposes a hierarchy of Services, Characteristics, and Descriptors. The Broadcaster and Observer roles are for transmitter- and receiver-only applications, BLE provides most of its functionality through key/valueīLE defines multiple roles that devices can play.
