4.2.2.10. AT+WSKEY
 Function: Set/Query WIFI security parameters as STA;
 Format:
 Query Operation
AT+WSKEY<CR>
+ok=<auth,encry,key><CR>< LF ><CR>< LF >
 Set Operation
AT+ WSKEY=< auth,encry,key><CR>
+ok<CR>< LF ><CR>< LF >
 Parameters:
 auth: Authentication mode
 OPEN
 SHARED
 WPAPSK
 encry:Encryption algorithm
 NONE: When “auth=OPEN”, effective
 WEP: When “auth=OPEN” or “SHARED”, effective
 TKIP: When ”auth= WPAPSK”, effective
 AES: When “auth= WPAPSK”, effective
 key: password, ASCII code, shall less than 64 bit and greater than 8bit
This Instruction only effective for HF-A21-SMT works as STA. After HF-A21-SMT module boots
up again, the setting will be effective. But user can set this command when module configured as
AP.
4.2.2.11. AT+WSSSID
 Function: Set/Query WIFI target AP SSID parameters as STA.
 Format:
 Query Operation
AT+WSSSID<CR>
+ok=<ap’s ssid><CR>< LF ><CR>< LF >
 Set Operation
AT+ WSSSID=<ap’s ssid ><CR>
+ok<CR>< LF ><CR>< LF >
 Parameters:
 ap‟s ssid: AP‟s SSID
This Instruction only effective for HF-A21-SMT works as STA. After HF-A21-SMT module boots
up again, the setting will be effective. But user can set this command when module configured as
AP.
4.2.2.12. AT+ WSLK
 Function: Query WiFi link status as STA
 Format:
 Query Operation
AT+ WSLK<CR>
+ok=<ret><CR>< LF ><CR>< LF >
 Parameters:
 ret
 ”Disconnected”, if no WiFi connection;
 ”AP‟ SSID（AP‟s MAC” ）, if WiFi connection available;
 ”RF Off”, if WiFi OFF;
This Instruction only effective for HF-A21-SMT works as STA. After HF-A21-SMT module boots
up again, the setting will be effective. But user can set this command when module configured as
AP.
