MT7697D IoT SiP Module
2017.10.13
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.
AI7697HD is a highly integrated SIP module which features an application processor, a low power
1x1 dual-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. AI7697HD also includes embedded
SRAM/ROM and an external 4MB serial flash.
The Wi-Fi subsystem contains the 802.11a/b/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.
The Bluetooth subsystem contains the Bluetooth radio, baseband, link controller. It also uses the
same 32-bit RISC CPU for the Bluetooth protocols.

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

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.
f 11 10.10.10.254 3 64
The ping stops after sending three packets to 10.10.10.254.
The ping usage is: f 11

- Example 2. Wi-Fi access point mode.
- Decide Wi-Fi access point settings:
- SSID
- Authentication Mode
- Encryption Type.
- Password
You need the above settings before proceeding.
- Once the information is collected, use the following commands to
configure the LinkIt 7687 HDK. This example assumes WPA2 PSK is used for
authentication, AES for encryption, 'iot_ap' (length 6) for the SSID,
and the password of WPA2 as '87654321' (length 8).

press reset button on the LinkIt 7687 HDK to restart the system.
- Use a handheld device or a laptop computer to connect to the access point
'iot_ap'. In the MT7687 console, the IP address assigned to the cellphone
or laptop is shown as below.

BLE mode
Use the command 'ble ?' and enter to query the available Bluetooth command line options.
- Input the command "ble gap start_scan 0 0024 0011 1 0" in the serial tool
to scan for the nearby Bluetooth enabled devices.
- 0, passive scan.
- 0024, scan interval (36 * 0.625 ms). Two bytes long HEX value.
- 0011, scan window (17 * 0.625 ms). Two bytes long HEX value.
- 1, own address type, 1 means random address.
- 0, filter policy.
