Wi-Fi AP/STA/P2P Mode Example

[中文]

This chapter shows three modes of BEKEN Wi-Fi module: STA、SoftAP、P2P.

  • Wi-Fi Enables STA mode

  • Wi-Fi Enables SoftAP mode

  • Wi-Fi Enables P2P Mode (under development)

Example and Configuration

STA and SoftAP modes are supported by default. The function of P2P need to enable macro CONFIG_COMPONENTS_P2P in file middleware/soc/bk72xx.defconfig .

Note

Please contact BEKEN support team for further details about P2P function

Source Code Process

Wi-Fi STA Mode

V1

The BEKEN Wi-Fi module runs a command to enter the corresponding mode. After entering net mode, user can view the supported mode.

net mode <mode>
     - net mode sta
     - net mode ap

The entry of STA mode is cmd_wlan_sta_exec which is located in properties/modules/bk_wifi_impl/wifi_wpa_cmd.c. This function configures/obtains the corresponding configuration through set/get command respectively. The common ones are as follows:

net sta config <ssid> [psk]
     - net sta config ssid_example
     - net sta config ssid_example psk_example

net sta set <field> <value>
     - net sta set ssid ssid_example
     - net sta set psk psk_example
     - net sta set scan_ssid (0, 1)
net sta enable
net sta disable

cmd example:
net sta enable
net sta config BEKEN_TEST 12345678
net sta connect

V2

On the basis of V1, BEKEN has completed the adaptation of second version of commands by customizing customer requirements. Comparing with original one, this version simplifies use of commands, a single command to achieve STA mode connection. The file locates at components/bk_cli/cli_wifi.c and it needs to enable macro CLI_CFG_WIFI=1. The usage of STA mode is as follows:

{"scan", "scan [ssid]", cli_wifi_scan_cmd}
{"sta", "sta ssid [password][bssid][channel]", cli_wifi_sta_cmd}
{"state", "state - show STA/AP state", cli_wifi_state_cmd}
{"stop", "stop {sta|ap}", cli_wifi_stop_cmd}

cmd example:
sta BEKEN_TEST 12345678

Note

V2 version is compatible with V1 version

Wi-Fi SoftAP Mode

The entry of SoftAP mode is cmd_wlan_ap_exec in V1 version and source code is same as STA mode. The main configuration parameters are SSID and password.

net ap set <field> <value>
     - net ap set ssid ssid_example
     - net ap set psk psk_example
net ap enable
net ap reload
net ap disable

cmd example:
net ap enable
net ap set ssid BEKEN_TEST
net ap set psk 12345678
net ap start

Entry of V2 version is cli_wifi_ap_cmd which is located in components/bk_cli/cli_wifi.c, the detailed introduction is as follows:

{"ap", "ap ssid [password]", cli_wifi_ap_cmd}
{"stop", "stop {sta|ap}", cli_wifi_stop_cmd}
{"state", "state - show STA/AP state", cli_wifi_state_cmd}

cmd example:
ap BEKEN_TEST 12345678

Note

BEKEN Wi-Fi module supports AP+STA coexist

Wi-Fi P2P Mode

P2P Mode is still under development. The entry function cmd_wlan_p2p_exec can be used to configure the SSID of P2P and default name is beken p2p . The role of P2P is decided by negotiating, but could be assigned by the value of param.intent . The command to enable P2P function is as follows:

net p2p enable
