Group “AT RDEV”: Devices within Range
AT commands starting with “AT RDEV” allow you to query and display
information about other
Bluetooth
®
devices in range.
9.11.1
AT RDEV FOUND ?
The
AT RDEV FOUND ?
command outputs the results list of the
Bluetooth
®
devices still within range since the last search again (see section “AT INQ
START”).
9.11.2
AT RDEV FOUND NAMES ?
The
AT RDEV FOUND NAMES ?
command attempts to query and display the
name for each
Bluetooth
®
device found. Because there is no guarantee that all
corresponding devices still in range are found, not all names may be released
under certain circumstances. The order may not be the same as in the list of
devices found.
However, the assignment can be made via the
Bluetooth
®
MAC ID.
