Part IV Expansion Module Function Demo
RTL8188 Module function demonstration（WIFI Client）
【Test instruction】：Connect to the WIFI AP using the RTL8188 as a wireless network card.
【Interface identifier】：WIFI、WIFI_ANT
【System equipment】：wlan0
Test operation
1. Make sure that the WIFI module is attached to the “WIFI” logo, otherwise no testing is required.
2. Connect the WIFI antenna to the interface labeled "WIFI_ANT".
3. Generate WPA PSK file for SSID
Command format: wpa_passphrase <ssid> [passphrase]
=====> Enter the command: wpa_passphrase MY-TEST-AP myzr2012 > /etc/wpa_supplicant.conf pkill wpa_supplicant
4. connection
=====> Enter the command: wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf =====> Output information: Successfully initialized wpa_supplicant rfkill: Cannot open RFKILL control device ==> rtl8188e_iol_efuse_patch IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready ......
5. Get IP
=====> Enter the command: udhcpc -i wlan0 =====> Output information: udhcpc (v1.23.1) started Sending discover... Sending select for 192.168.43.121... Lease of 192.168.43.121 obtained, lease time 3600 /etc/udhcpc.d/50default: Adding DNS 192.168.43.1
6. Test connection
=====> Enter the command: ping -I wlan0 192.168.43.1 -c 2 -w 4 =====> Output information: PING 192.168.43.1 (192.168.43.1) from 192.168.43.130 wlan0: 56(84) bytes of data. 64 bytes from 192.168.43.1: icmp_seq=1 ttl=64 time=5.66 ms 64 bytes from 192.168.43.1: icmp_seq=2 ttl=64 time=9.22 ms --- 192.168.43.1 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 5.663/7.444/9.226/1.783 ms
Test Results
“0% packet loss” means WIFI connection is normal.
RTL8188 Module function demonstration（WIFI AP mode）
【Test instruction】：Use RTL8188 as the WIFI AP and connect your phone to this AP.
【Interface identifier】：WIFI、WIFI_ANT
【System equipment】：wlan0
Test operation
1. Make sure that the WIFI module is attached to the “WIFI” logo, otherwise no testing is required.
2. Connect the WIFI antenna to the interface labeled "WIFI_ANT".
3. Configure IP for wlan0:
=====> Enter the command: ifconfig wlan0 192.168.99.1 =====> Output information: ==> rtl8188e_iol_efuse_patch IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
4. Enable the DHCP service for wlan0:
=====> Enter the command: touch /var/lib/misc/udhcpd.leases udhcpd -f /etc/my_udhcpd.conf & =====> Output information: [1] 469 udhcpd (v1.23.1) started
5. Enable Host-AP feature for wlan0
=====> Enter the command: hostapd /etc/my_hostapd.conf -B =====> Output information: Configuration file: /etc/my_hostapd.conf rfkill: Cannot open RFKILL control device Using interface wlan0 with hwaddr e0:b9:4d:7f:e4:40 and ssid "MY_HOSTAP_V25" RTL871X: set group key camid:1, addr:00:00:00:00:00:00, kid:1, type:AES wlan0: interface state UNINITIALIZED->ENABLED wlan0: AP-ENABLED
5. Client device connected to Host-AP
At this point, the development board's Host-AP function is enabled, the client device can search for "MY_HOSTAP_V25" and connect to this AP with the password "myzr2012".
Test Results
1. Information generated when the device is successfully connected
=====> Output information: Sending OFFER of 192.168.12.20 Sending OFFER of 192.168.12.20 Sending ACK to 192.168.12.20
2. Information generated when a device is disconnected
=====> Output information: RTL871X: OnDeAuth(wlan0) reason=3, ta=b4:0b:44:f5:64:2f RTL871X: clear key for addr:b4:0b:44:f5:64:2f, camid:4
EC20 Module test
【Test instruction】：After the 4G connection is successful, the development board sends an ICMP packet to the external network to verify that the connection is normal.
【Interface identifier】：MINI_PCIE
【System equipment】：eth2
Test operation
1. The development board is powered off, connected to the 4G module, connected to the antenna and inserted into the SIM card to start the evaluation board.
2. Use the instructions to make a network connection:
