Introduction

                     After the updating  Updation of dynamic hostapd changes in wifi WiFi hal layer , we are able to resolve plenty of lead to resolution of various issues like timeout errors while trying when we try to set any values to wifi parameters (such as ssid, password, SecurityMode, channel ..) ,etc through dmcli commands or WebUI. Moreover, features such as xfinity-wifi,snmp set/get of wifi calls ,factory-reset features via dmcli commands or WebUItimeout errors are also resolved. This will enhanced the Performance performance of WebUI. 

We can achieved resolved this feature scenario with support of hostapd_cli.
hostapd_cli - is a text-based frontend program for interacting with hostapd.
hostapd is a user  space daemon  for access point and authentication servers. It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators and RADIUS authentication server.

Design Considerations

                   Upgraded hostapd version from 2.2 to 2.5 in emulator because this version have the support of hostapd  enabling /disabling  at runtime

disabling of hostapd  at runtime  through hostapd_cli.

Following wifi hal api's are added and modified in wifi_hal.c ,

Modified wifi hal api's are :

1. wifi_setSSIDName()
2. wifi_getApEnable()
3. wifi_getApStatus()
4. wifi_setApSsidAdvertisementEnable()
5. wifi_setSSIDEnable()
6. wifi_setApEnable()
7. wifi_getSSIDStatus()
8. wifi_setPreferPrivateConnection()
9. wifi_stopHostApd()
10. wifi_startHostApd()
11. wifi_restartHostApd()
12. wifi_setApEnable()
13. wifi_setApSecurityModeEnabled()
14. wifi_setApSecurityPreSharedKey()
15. wifi_setApSecurityKeyPassphrase()
16. wifi_setApWpsEnable()
17. wifi_setApWpsConfigMethodsEnabled()
18. wifi_setApWpsDevicePIN()
19. wifi_getRadioEnable()
20. wifi_setRadioEnable()
21. wifi_getRadioStatus()
22. wifi_setRadioChannelMode()
23. wifi_setRadioChannel()
24. wifi_setRadioAutoChannelEnable()
25. wifi_setRadioOperatingChannelBandwidth()
26. wifi_setApSecurityKeyPassphrase()

Newly added dynamic wifi hal api's:

1. Stop_Start_Broadcasting_SSID_Names_Hostapd_Process()
2. GetInterfaceName_HostapdConf()
3. Dynamically_Disabling_hostapd_process()
4. Dynamically_Enabling_hostapd_process()
5. Dynamically_Updated_SupportedRated_hostapd_process()
6. Dynamically_Updated_Password_hostapd_process()
7. Dynamically_Updated_SSIDAdvertisement_Hostapd_Process()
8. Dynamically_Updated_SSIDName_Hostapd_Process()
9. DYnamically_Updated_OperatingChannelBandwidth()
10. Dynamically_Updated_Security_Encryption_Modes_Hostapd_Process()
11. Dynamically_Updated_Channel_Value_hostapd_process()
12. Dynamically_Enabling_And_Disabling_WPS_Support_Hostapd_Process()
13. Dynamically_Updated_WPS_ConfigMethods_Hostapd_process()
14. Dynamically_Updated_WPS_ApPin_Hostapd_Process()
