This project is an extension for LinkIt Connect 7681 (SDK v1.7.1).
LinkIt Connect 7681 is an product of Mediatek Labs (http://labs.mediatek.com/site/global/developer_tools/mediatek_7681/whatis_7681/index.gsp)
It is basically a Wi-Fi module. But the SDK does not include enough AT command. This project try to add AT command so that it can be used by Arduino or other micro controller
| AT Command | Description | Syntax | Result |
|---|---|---|---|
| AT+WSWM | SWitch Mode between Station/AP mode | AT+WSWM? AT+WSWM=1 (switch to STA) AT+WSWM=2 (switch to AP) |
+WSWM:1 or 2 OK OK |
| AT+WMAC | query MAC address of 7681 | AT+WMAC? | +WMAC:<mac> |
| AT+WCAP | (Station only) Connect to an AP | AT+WCAP=<ssid>,<key>,<auth> | OK ～ +WCAP=<ssid>,<key>,<auth>,<mac> |
| (Station only) disconnect from AP | AT+WCAP= | +WCAP= | |
| AT+WQIP | (Station only) Query IP | AT+WQIP? | +WQIP=<ip>,<gateway>,<dns> |
| AT+WAPC | (AP only) AP Configuration | AT+WAPC? AT+WAPC=<ssid>,<key>,<auth> |
+WAPC=<ssid>,<key>,<auth> OK |
| AT+WDNL | Domain Name Lookup | AT+WDNL=<server name> | OK ～ +WDNL:<server name>,<ip> |
| AT+WSO | Socket Open, connect to remote server | AT+WSO=<serverip>,<port>,<type> | +WFO:<lport> |
| AT+WSL | Socket Listen, listen port | AT+WSL=<port>,<type> | OK |
| AT+WSW | Socket Write, send data | AT+WSW=<lport>,<data> | OK, ERROR, BUSY ～ +WSDS:<lport> |
| AT+GPI0~4 | Control GPIO 0~4 | AT+GPI0? AT+GPI0=0 or 1 |
+GPI0:0 or 1 OK |
| AT+GPW0~4 | Control PWM 0~4 | AT+GPW0? AT+GPW0=<dutycycle>,<resolution> |
+GPW0:<dutycycle>,<resolution> OK |
