 TKIP: When “auth=WPAPSK”, effective;
 AES:When “auth=WPAPSK”, effective;
 TKIPAES: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 AP. After HF-A21-SMT module boots up
again, the setting will be effective. But user can set this command when module configured as
STA.
4.2.2.16. AT+HIDESSID
 Function: Set/Query hide AP‟s SSID;
 Format:
 Query Operation
AT+ HIDESSID <CR>
+ok=<sta.><CR>< LF ><CR>< LF >
 Set Operation
AT+ HIDESSID=<sta><CR>
+ok<CR>< LF ><CR>< LF >
 Parameters:
 When Query,sta reply if module‟s SSID is hide;
 On – not hide SSID;
 Off - hide SSID;
 When Set,
 Off - hide SSID;
 On - not hide SSID;
4.2.2.17. AT+MSLP
 Function: Set modules into power save mode.(Turn OFF WiFi);
 Format:
 Query Operation
AT+ MSLP <CR>
+ok=<sta.><CR>< LF ><CR>< LF >
 Set Operation
AT+ MSLP=<on/off><CR>
+ok<CR>< LF ><CR>< LF >
 Parameters:
 When Query,sta reply if the module in sleep mode;
 On - Module not in sleep mode (WiFi ON);
 Off - Module in sleep mode(WiFi OFF);
 When Set,
 Off - Set module to sleep mode (WiFi OFF);
 On - Set module to normal mode (WiFi ON);
When module go into sleep mode, user can input “AT+MSLP=on” to re-start the module and
module go into transparent transmission mode.
4.2.2.18. AT+WSCAN
 Function: Seek AP when module works as STA mode;
 Format:
AT+ WSCAN<CR>
+ok=<ap_site><CR>< LF ><CR>< LF >
 Parameters:
 ap_site: AP searched;
4.2.2.19. AT+ TCPLK
 Function: Query if TCP link already build-up;
 Format:
