Figure 4.4 - Frame Display Extended Inquire Response
EIR displays extensive information about the Bluetooth® devices that are discovered as data is being captured. EIR
provides more information during the inquiry procedure to allow better filtering of devices before connection;
and sniff subrating, which reduces the power consumption in low-power mode.Before the EIR tab was created,
this type of information was not available until a connection was made to a device. Therefore, EIR can be used to
determine whether a connection can/should be made to a device prior to making the connection.
Note: If a Bluetooth device does not support Extended Inquiry Response, the tab displays
Received Signal Strength Indication (RSSI) data, which is less extensive than EIR data.
