Wi-Fi OPENING INSTRUCTION

Version 1.0

1. Kernel Concentration¶

Spinand flash
```
make infinity2m_ssc011a_s01a_minigui_defconfig

make menuconfig
```
Enter Networking support -> Wireless, and change the following option from module compilation to build-in.

Enter Device Drivers->Generic Driver options, change the following compile method to build-in.
Nor flash
```
make infinity2m_ssc011a_s01a_minigui_defconfig

make menuconfig
```
Enter Networking support -> Wireless, and change the following option from module compilation to build-in.

2. kernel compilation¶

make clean –j16;make –j16

Generate kernel/arch/arm/uImage.xz after success, copy it to SDK and replace the file with the same name.

The target path of Spinand: project/release/nvr/i2m/011A/glibc/8.2.1/bin/kernel/spinand

The target path of Nor: project/release/nvr/i2m/011A/glibc/8.2.1/bin/kernel/

Modify the configuration of SDK, add interface_wlan:=enable in project/release/customer_tailor/nvr_i2m_display_glibc_tailor.mk, and then compile SDK.

3. Enable/Disable WIFI in APP¶

Modify SSD_sample/jni/Makefile:

Enable wifi:
Disable wifi:

4. WIFI Test¶

Modify /appconfigs/wpa_supplicant.conf, and add AP:

The tested ssid is "SKY", password is "12345678".

wifi initialization
```
cd /config/wifi

./ssw01bDeInit.sh

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/lib:/config/wifi
```
Copy the corresponding ko to /config/wifi when the other wifi ko are used, then modify ssw01bInit.sh, insmod the dependent ko.

Test wifi connection

./wpa_supplicant -Dnl80211 -i wlan0 -c /appconfigs/wpa_supplicant.conf -d &

sleep 2

udhcpc -q -i wlan0 -s /etc/init.d/udhcpc.script &

WLAN scanning
```
./iwlist wlan0 scanning
```

5. Wifi Application Example¶

Source code：

Refer to wifiDemo.rar.

Steps:

Modify sample code, add the specified wifi information.
Modify PROJECT_PATH in Makefile, use the local SDK path, and then compile the demo code:
Copy the generated testWifi to the target board and run

The prompt is as follow:

Enter 'm' to switch STA/AP mode, the default is STA mode;

In the code, you can preset the list of wifi to be connected, enter ‘a’ to switch to the next one, and start looping from 0 by default;

Enter 'n' to connect the designated wifi in STA mode, open the personal wifi in AP mode;

Enter 'd' to disconnect in STA mode, close the personal wifi in AP mode;

Enter 'p' to print the information currently scanned in STA mode, and print the connected device information in AP mode;

Enter 'q' to quit app.
