wifi/simdriver: Support the sim wifi.
Add the Sim WiFi function, which can provide the wifi operating on nuttx sim emulator, and support two modes that simulate wifi, HWSIM and RNC(real network card). - In the HWSIM mode, we simulates two wlan interfaces. The wlan0 is STA and the wlan1 is AP. The wlan0 can connect to the wlan1 in the nuttx simulator. - In the RNC mode, we can use the same wlan interface name on the nuttx simulator to control the connection behavior of the real wireless card.

# Function
|
||||
|
||||
The simwifi can provides host Settings for sim wifi on nuttx sim emulator.
|
||||
The script sim_wifi.sh supports two modes that simulate wifi, HWSIM and RNC
|
||||
(real network card).
|
||||
|
||||
- In the HWSIM mode, we simulates two wlan interfaces. The wlan0 is STA and
|
||||
the wlan1 is AP. The wlan0 can connect to the wlan1 in the nuttx simulator.
|
||||
- In the RNC mode, we can use the same wlan interface name on the nuttx simulator
|
||||
to control the connection behavior of the real wireless card.
|
||||
|
||||
# Config
|
||||
|
||||
Before using the Sim WiFi function, we need to perform the following
|
||||
configurations:
|
||||
|
||||
- nuttx
|
||||
SIM_NETDEV_NUMBER=3
|
||||
SIM_WIFIDEV_NUMBER=2
|
||||
SIM_NETDEV_TAP=y
|
||||
DRIVERS_IEEE80211=y
|
||||
NETDEV_WIRELESS_HANDLER=y
|
||||
|
||||
- apps
|
||||
WIRELESS_WAPI_CMDTOOL=y
|
||||
SYSTEM_DHCPC_RENEW=y
|
||||
NETUTILS_DHCPD=y
|
||||
|
||||
# Using
|
||||
|
||||
We can use the './tools/simwifi/sim_wifi.sh help' command to view the commands
|
||||
provided by the sim_wifi.sh script and the results are as follows.
|
||||
|
||||
sim_wifi.sh (rename <old> <new> |
|
||||
init <wan> <mode> |clean |
|
||||
start_wpa <wlan0> |stop_wpa |
|
||||
start_hostapd <wlan0> |stop_hostapd |
|
||||
start_udhcpc <wlan0> |stop_udhcpc |
|
||||
start_dhcp <wlan0> |stop_dhcp |
|
||||
start_hwsim |stop_hwsim |up_hwsim |
|
||||

|
||||
start_sta <wlan0> |stop_sta |
|
||||
start_ap <wlan0> [eth0] |stop_ap <wlan0> [eth0] |
|
||||
start_bridge <eth0> |stop_bridge <eth0> |
|
||||
show | help)
|
||||
|
||||
- Init the simwifi, the command format is as follows:
|
||||
sudo ./tools/simwifi/sim_wifi.sh init <wan> <mode>
|
||||
|
||||
The <wan> is the name of the interface for accessing the Internet.
|
||||
The <mode> is the simwifi mode, HWSIM and RNC.
|
||||
|
||||
Setting HWSIM:
|
||||
sudo ./tools/simwifi/sim_wifi.sh init eno1 HWSIM
|
||||
|
||||
Setting RNC:
|
||||
sudo ./tools/simwifi/sim_wifi.sh init eno1 RNC
|
||||
|
||||
- In HWSIM mode:
|
||||
Start the hwsim services, the command is as follows.
|
||||
sudo ./tools/simwifi/sim_wifi.sh start_hwsim
|
||||
|
||||
Stop the hwsim services, the command is as follows
|
||||
sudo ./tools/simwifi/sim_wifi.sh stop_hwsim
|
||||
|
||||
|
||||
- In RNC mode:
|
||||
Maybe the real wireless card name format is not wlanx, in this case
|
||||
we need to change it to wlanx format. The command is as follows
|
||||
sudo simwifi rename <old_name> wlanx
|
||||
|
||||
* Set the real wireless network card to STA mode.
|
||||
sudo ./tools/simwifi/sim_wifi.sh start_sta wlan0
|
||||
|
||||
* Set the real wireless network card to AP mode.
|
||||
sudo ./tools/simwifi/sim_wifi.sh start_ap wlan0
|
||||
|
||||
Finally we can clean up all the files, configurations and services of the simwifi.
|
||||
sudo ./tools/simwifi/sim_wifi.sh clean
|
||||
|
||||
# Location problems
|
||||
We can use the following command to locate the problem and display the
