4. Configuring the HDK
HDK includes a main board and a relative AI76X7H series stamp module. The stamp module is
mounted on the PCBA bottom side. The simple steps to start-up EVK is shown as below:
1. CON6 is connector GND
2. CON3 is connector 3.3V (module power supply)
3. CON7 is connector RST button to module NRST pin
4. CON4 is connector UART RX
5. CON1 is connector UART TX
4.1. Configuring the HDK to Normal mode
1. Make sure that CON31 has no jumper on it.
2. Connect computer and EVK via micro USB cable.
3. On board FTDI chip transfers module TTL signal to PC USB port.
(GPIO2/GPIO3；UART baud rate：57600)
4. Micro USB is debug UART and it can apply AT Command in RTOS environment.
FOR Example：
Station Mode
Connect to “AcSiP_Public” AP
Change the Operation Mode to Station Mode:
wifi config set opmode 1
Set SSID:
wifi config set ssid 0 AcSiP_Public
Configure auth information:

wifi config set psk 0 7 8 "acsip@public"
The parameter definition of wifi config set psk:
wifi config set psk [port] [auth mode] [encrypt type] [psk key]
Apply changes:
wifi config set reload
Wait for few seconds, the message like below would show up if connecting to the AP successfully:
[T: 5066238 M: common C: INFO F: ip_change_call_back L: 441]: ************************
[T: 5066239 M: common C: INFO F: ip_change_call_back L: 442]: DHCP got IP:192.168.20.67
[T: 5066239 M: common C: INFO F: ip_change_call_back L: 443]: ************************
Get RSSI:
wifi connect get rssi
AP Mode
Change the Operation Mode to AP Mode:
wifi config set opmode 2
Change Wireless Mode:
wifi config set wirelessmode 1 [wireless mode]
Change Country:
wifi config set country [band(0 for 2.4G, 1 for 5G)] [region]
Change Channel:
wifi config set ch 1 [channel number]

wifi config set reload
Change Bandwidth:
wifi config set bw 1 [bandwidth(0 for 20MHz, 1 for 40MHz)]
Get the Station List for analyzing the status of clients which connected to this AP:
wifi connect get stalist
The response sample of Station List:
stalist size=1
0
last_tx_rate: MCS=7, LDPC=0, MODE=2
last_rx_rate: MCS=8, LDPC=0, MODE=1
rssi_sample.LastRssi0)=-25

addr=cc:3d:82:2c:c1:9e
power_save_mode=1
bandwidth=0
keep_alive=0
wifi_connection_get_sta_list, status:0
4.2. Configuring the HDK to Recovery mode
1. Setting the CON31 jumper and push RST button for Recovery mode.
(In Recovery mode，Debug UART message showed “ccc”)
2. Connect computer and EVK via micro USB cable.
3. On board FTDI chip transfers module TTL signal to PC USB port.
(GPIO2/GPIO3；UART baud rate：57600)
4. In recovery mode ,there are two function can be used
1. RF performance test (MTK QA tool)
2. Update module image (MT76x7_Flash_Tool)
