MT7687 IoT SiP Module
Feb 21, 2017
1. Description
AcSiP Technology Corp. introduces a low-cost and low-power consumption IoT module. This
stand-alone module is an operating system designed for wearable or internet of things (IoT) devices
with smart connection and cloud application/services.
AI7687H is a highly integrated SIP module which features an application processor, a low power 1x1
11n single-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit. The
application processor subsystem contains an ARM Cortex-M4F MCU, which has many peripherals,
including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC. AI7687H also includes embedded
SRAM/ROM and a SPI 2MB serial flash.
The Wi-Fi subsystem contains the 802.11b/g/n radio, baseband, and MAC that are designed to meet
both the low power and high throughput application. It also contains a 32-bit RISC CPU that could
fully offload the application processor.

Command
1. Software operating

Connect the board to PC with a serial port cable.

Build the example project and download the binary file to the MT7687.

Reboot the HDK, the console will show "FreeRTOS Running" message to indicate the HDK is booting up.

Use '?' and enter to query the available command line options.

Note that the command line options are still under development and subject to change without notice.

Below are two examples to demonstrate the Wi-Fi station and Wi-Fi access point modes of MT7687.

Example 1. Wi-Fi station mode.


Find your Wi-Fi access point settings:
Before connecting to a Wi-Fi access point, the following information needs to be collected:
1. What is the SSID of your Wi-Fi access point?
2. What is the authentication mode of your Wi-Fi access point?
In general, it is WPA PSK or WPA2 PSK. If you want to use different settings, please read
the table 'Table 1. Supported AuthMode(s)' at the bottom of this example.
3. What is the password of your Wi-Fi access point?
4. What is the encryption mode of your Wi-Fi access point?
In general, AES or TKIP is used. If you want to use different settings, please read the table
'Table 2. Supported EncrypType(s)' at the bottom of this example.
Once you have this information, use the following commands to configure the HDK. This
example assumes you want to use either WPA PSK or WPA2 PSK,your packets are encrypted

with TKIP or AES, the access point SSID is 'myhome' (length 6), and the password of WPA or
WPA2 is '12345678' (length 8).
config write STA AuthMode 9
config write STA EncrypType 8
config write STA Ssid myhome
config write STA SsidLen 6
config write STA WpaPsk 12345678
config write STA WpaPskLen 8
config write common OpMode 1
Press the reset button on the LinkIt 7687 HDK to restart the system.
Boot up with the new configuration.
If everything is correct, similar messages will be shown in the console to notify your HDK has
received an IP address.
************************
DHCP got IP:10.10.10.101
************************
PING from the LinkIt 7687 HDK (SDK v3.1.0)
If the IP address is fetched and the network is operating, the LinkIt 7687 can ping other
devices/computer on the network with the following command in the console.

2. Federal Communication Commission Interference Statement
This 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.
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 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.
FCC Caution:

Any changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate this equipment.

This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator &
your body.
This device is intended only for OEM integrators under the following conditions:
1)The antenna must be installed such that 20 cm is maintained between the antenna and users, and the
maximum antenna gain allowed for use with this device is 2 dBi.
2) The transmitter module may not be co-located with any other transmitter or antenna.
As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM
integrator is still responsible for testing their end-product for any additional compliance requirements
required with this module installed.
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC authorization is no longer
considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM
integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a
separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed such that
20 cm may be maintained between the antenna and users. The final end product must be labeled in a
visible area with the following: “Contains FCC ID: 2ADWC-AI7687H”. The grantee's FCC ID can be
used only when all FCC compliance requirements are met.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install
or remove this RF module in the user’s manual of the end product which integrates this module. The end
user manual shall include all required regulatory information/warning as show in this manual.
