(OEM/Integrators Installation Manual)
Product Overview
AB1602 is a low-power, single-chip Bluetooth Low
Energy Single mode controller. It integrates a
low-power physical layer, a link controller with a
security engine. It supports the standard HCI
interface which is able to connect to different
MCUs for varies applications. The SPI and UART
interface are used for connecting to external host
MCU and the Bluetooth profiles are implemented
on the host MCU as well.

1 Introduction
The Airoha AB1602 Family Lab Test Tool provides a quick-and-easy test suite for Airoha AB1602 devices.
Three basic functions including TX, RX and Crystal Trim are included in this utility. User may use this tool
to perform continuous TX, Burst TX, RX BER and Crystal Clock Trimming to test Airoha AB1602 Family
products.
1.1 Supported Chips
The Airoha AB1602 Family Lab Test Tool supports AB1602.

2 Environment Setup
2.1 Hardware Setup
An UART interface is used for PC-to-DUT connection. User may also use an USB-to-UART adaptor at PC
side and then connect to DUT side. A reference connection diagram is shown in figure 2-1.
Figure 2-1
If an USB-to-UART adaptor made by Airoha is used (as in Figure 2-2), the J1 connector (to DUT) pin
definition is shown in Figure 2-3. The VCC selection on JP12 should be set to +3.3V (with a jumper).

2.2 Software Setup
If the AIROHA USB-to-UART adaptor board is used, the driver should be installed at first
(PL2303_Prolific_DriverInstaller_v110.exe). When the driver is installed and the board is connected to PC,
an USB-to-Serial COM port would be presented in the device manager as in figure 2-4.

When installing the Airoha AB1602
will be shown during the installation.

3 The User Interface
Figure 3-1 shows the user interface when Airoha Lab Test Tool is launched. Three regions: COM port
selection & .airoha save/write, Function Tab, and Output Window are included in the user interface.

Connection Process
Power-on the DUT, and press the connection button of the device to enter discoverable mode.
Select corresponding COM port number of DUT in the COM Select region of the Lab Test Tool, and
will be shown in the output window, as in figure 3-2 and figure 3-3.

If the success message is not shown, please check if the DUT is correctly powered up, the link between
DUT and PC is correctly connected, and the DUT is in discover
again.
4 Test Functions
4.1 TX Test
There are three modes supported in the TX Test functions, i.e. Single-tone TX, Continuous TX and Burst
TX.

Single Tone Transmission
When CTX_START is selected, a continuous single-tone signal without any modulation (i.e. Carrier Only)
will be sent out at RF port. User may first set different RF frequency and TX power setting on the
from 2402 to 2480, and Tx GC ranges from 16 to 63.
To save the current Tx GC setting, click the Write to EEPROM button.

Continuous Data Transmission
When CTX_DATA is selected, a continuous modulated signal will be sent out at RF port. User may
first set different RF frequency, TX power setting, and choose modulation type with data format on the
from 2402 to 2480, and Tx GC ranges from 16 to 63. The data format supports all 0, all 1, 1010, and PN.
GFSK, 1/4pi-DQPSK, and D8PSK are supported for the modulation type.
To save the current Tx GC setting, click the Write to EEPROM button.
