Product Overview
The Air2U universal Class2 Bluetooth Module BSM02B-G is a compact and BQB
qualified module that provides a complete 2.4GHz Bluetooth system for data and
voice communications. This module is optimized for fast implementation in various
applications to enable electronic devices to communicate wirelessly with other
Bluetooth enabled devices. For example, the module can be used in applications
such as Laptop PC, PC accessories, PDA, access points and other embedded
integration applications. The BSM02B-G, Air2U’s core universal class2 Bluetooth
Module, comes without an antenna or connector and is designed to operate in
commercial temperature range. Extra reference designs, such as a class1 device
design or a system antenna integration design can also be supported by Air2U to
meet customers’ specific requirements. Standard software for the BSM02B-G
Bluetooth module includes the lower layer protocol stack software up to the host
interface (HCI). The upper layer protocol stacks, profiles, and application software
are also available directly from Air2U in a case by case design base. This module
also complies with RoHS instructions.

You can force SiW3500 module to download mode. In this mode, you can
download the firmware and nvm parameter. The procedure to force the module to
download mode are
1. Connect TP9~12 to “Signal Converter Board”. (This board can be provided from
Air2U.)
2. Connect TP29 to VCC.
3. Connect RS232 cable between “Signal Converter Board” and PC.
4. Give the power to SiW3500 module. (SiW3500 module’s VCC and GND can be
shared with Signal Converter Board’s.)
5. In PC side, launch the download program provided by Air2U.
If it is necessary to upgrade firmware, you need to reserve some components on
your board as:
(Suggestion)
For normal customer’s usage, R1~R4 should be mounted and J1 can be
non-mounted. Once you need to upgrade firmware, you can mount J1 and remove
R1~R4. Then, follow “Download Process” as above,

The device complies with Part 15 of the FCC rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference
that may cause undesired operation.
2. This device and its antenna(s) must not be co-located or operating in
conjunction with any other antenna or transmitter.
3. Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user authority to operate the
equipment.
4. This Equipment has been tested and found to comply with the limits for a class B
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
