AI7697HD MT7697D IoT SiP Module A 2017.10.13 1 of 12 Product Name Version Date Page 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. 1.1.

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.

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
