Raw Data
29
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.
Air Interface
The client software only
shows high level functions
