13.0 Usage Scenarios
13.1 SCENARIO 1: POINT-TO-POINT
CONNECTION
LMX9820 acts only as slave, no further configuration is
required.
Example:
Sensor with LMX9820; hand-held device with
standard Bluetooth option.
The SPP conformance of the LMX9820 allows any device
using the SPP to connect to the LMX9820.
Because of switching to Transparent automatically, the
controller has no need for an additional protocol layer; data
is sent raw to the other Bluetooth device.
On default, a PinCode is requested to block unallowed tar-
geting.
