13.1 SCENARIO 1: POINT-TO-POINT
CONNECTION
LMX9820A acts only as slave, no further configuration is
required.
Example:
Sensor with LMX9820A; hand-held device with
standard Bluetooth option.
The SPP conformance of the LMX9820A allows any device
using the SPP to connect to the LMX9820A.
By switching to transparent mode automatically, the con-
troller 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.
