+The android.hardware.uwb.fira_android package is used to add any Android specific
+additions to the UCI specification defined by FIRA standards body. These
+additions should be added to the vendor specific portions carved out in the UCI
+specification.
+
+These include:
+ - Android specific GIDs/OIDs for commands/responses/notifications.
+ - Andriod specific params in an existing UCI specified command/response/notification.
+
+All other interactions sent/received over the HAL interface is expected to
+comply with the UCI specification that can be found here:
