9.0 Functional Description
9.1 BASEBAND AND LINK MANAGEMENT
PROCESSORS
Baseband and Lower Link control functions are implemented
using a combination of National’s CompactRISC 16-bit pro-
cessor and the Bluetooth Lower Link Controller. These pro-
cessors operate from integrated ROM memory and RAM and
execute on-board firmware implementing all Bluetooth func-
tions.
9.1.1 Bluetooth Lower Link Controller
The integrated Bluetooth Lower Link Controller (LLC) com-
plies with the Bluetooth Specification version 2.0 and imple-
ments the following functions:
9.1.2 Bluetooth Upper Layer Stack
The integrated upper layer stack is prequalified and includes
the following protocol layers:
Adaptive Frequency Hopping
Interlaced Scanning
Fast Connect
Support for 1, 3, and 5 slot packet types
79 Channel hop frequency generation circuitry
Fast frequency hopping at 1600 hops per second
Power management control
Access code correlation and slot timing recovery
L2CAP
RFComm
SDP
Transceiver Return Loss

9.1.3 Profile support
The on-chip application of the LMX9830 allows full stand-
alone operation, without any Bluetooth protocol layer neces-
sary outside the module. It supports the Generic Access
Profile (GAP), the Service Discovery Application Profile
(SDAP), and the Serial Port Profile (SPP).
The on-chip profiles can be used as interfaces to additional
profiles executed on the host. The LMX9830 includes a con-
figurable service database to answer requests with the pro-
files supported.
9.1.4 Application with command interface
The module supports automatic slave operation eliminating
the need for an external control unit. The implemented trans-
parent option enables the chip to handle incoming data raw,
without the need for packaging in a special format. The device
uses a pin to block unallowed connections. This pincode can
be fixed or dynamically set.
Acting as master, the application offers a simple but versatile
command interface for standard Bluetooth operation like in-
quiry, service discovery, or serial port connection. The
firmware supports up to seven slaves. Default Link Policy set-
tings and a specific master mode allow optimized configura-
tion for the application specific requirements. See also
Section 11.0 Integrated Firmware.
9.1.5 Memory
The LMX9830 introduces 16 kB of combined system and
Patch RAM memory that can be used for data and/or code
upgrades of the ROM based firmware. Due to the flexible
startup used for the LMX9830 operating parameters like the
Bluetooth Device Address (BD_ADDR) are defined during
boot time. This allows reading out the parameters of an ex-
ternal EEPROM or programming them directly over UART.
