8.11.5 Subgroup “AT RDEV PORT”
AT commands starting with “AT RDEV PORT” allow the retrieval of information
on SPP services provided by external devices.
8.11.5.1 AT RDEV PORT INDEX <Target Device>
The
AT RDEV PORT INDEX <target device>
command queries the port
numbers of the SPP services that the target device provides. For a definition of the
target device, see section “AT RDEV NAME <device>". If the target device is a
WSA, the query returns two results – port indexes 1 and 2.
8.11.5.2 AT RDEV PORT NAME <Device>

AT RDEV PORT NAME <device>
command queries the names of the
