1 General
BlueNiceCom 4
Bluetooth-Modul with UART-interface and integrated Chip-antenna
• Bluetooth Class 2 module
• Bluetooth Specification 2.0 compatible
• Support of Bluetooth Audio
• Integrated profiles: SPP, GAP, SDAP
• Supported profiles: DUN, OBEX, HSP etc.
• UART interface
• Integrated chip antenna
AMBER wireless provides with the BlueNiceCom 4 a certified, qualified listed Bluetooth-module,
based on LMX9830 from National Semiconductor. This compact and inexpensive Bluetooth-
module is qualified for a serial data or audio transmission.
The module has an integrated chip-antenna and can be placed into a circuit like a SMD-part.
BlueNiceCom IV comes with an integrated firmware with the complete Bluetooth Stack
(Bluetooth 2.0).
A Point-to-Point connection and a Point-to-Multipoint (Piconet) connection are supported by the
firmware. Up to seven active links (Piconet) and one SCO-link (Audio) is possible.
The module can be integrated easily in a system. According to the application and the settings
the BlueNiceCom 4 can work as a stand-alone-slave-module e.g. as a virtual cable replacement
in combination with another commercial Bluetooth system.
A development environment AMB2300-EV is available.

The signal level is equivalent to the power consumption (2.9V to 3.6V) of the BlueNiceCom 4
and has to be matched, if the Host system is working with a different signal level.

2.2.3 UART configuration with OP3, OP4, OP5
The serial interface of the AMB2300 must be configured as follows:
Level note
0 = low open pin
1 = high VCC with 1KΩpull up
*exception OP3: VCC without pull up!
OP3, OP4 and OP5 are pulled down in AMB2300, therefore these pins for the low level are not
to be switched at GND. Here an example of circuit:
OP3* OP4 OP5 Function
0 0 0 Not supported
0 1 0 Not supported
1* 0 0 UART speed read from NVS (EEPROM)
1* 0 1 UART speed 9.6 kbps
1* 1 0 UART speed 115.2 kbps
1* 1 1 UART speed 921.6 kbps

2.2.4 UART interface RX_BT, TX_BT, RTS#_BT and CTS#_BT
The interface serves for communication with the BlueNiceCom4. The hardware handshake is
used (RTS/CTS). If this should not be supported by the host system, RTS#_BT and CTS#_BT
must be short circuit and/or CTS#_BT put on Low levels. This can lead however to overrun! We
recommended therefore urgently to use handshake.

2.3 Dimension
BlueNiceCom 4 has 1mm x 2mm soldering pads with a raster of 2mm to be solder direct on a
motherboard

3 Details for Layout
To achieve the maximum of range no metal (ground, strip line, components, etc..) has to be
near the antenna, as shown hatched in the following figure. The antenna should have a
distance of 8mm to any ground, strip line or component. Most suitable is to place the antenna at
the margin of the motherboard.
The BNC4 is not isolated, so even if there are normally no short circuit problems, because of
the solder resist, an isolation should be placed between BNC4 and motherboard in case of any
copper on the top side of the motherboard underneath the BNC4.
4 Soldering & Reflow
4.1 Description
•On demand there are taped– automatic assembly – and vacuum packed – reflow
solderable – components available.
•The temperature curve depends on the motherboard its character, like the number and
conditioning of parts, etc. Please ask your manufactor.
•Depending on the limit values of the components following limits are not allowed to excess
260°C max. 40s (LMX)
250°C max. 20s (Chip-antenna)
200°C max. 120s (Chip-antenna)
