RDKB Reference Platform - Dynamic Hostapd Changes in WiFi Hal - Design Approach

Introduction

                     After the updating of dynamic hostapd changes in wifi hal layer, we are able to resolve plenty of issues like timeout errors while trying to set any wifi parameters(ssid,password,SecurityMode,channel..) ,xfinity-wifi,snmp set/get of wifi calls ,factory-reset features via dmcli commands or WebUI. This will enhanced the Performance of WebUI .  We can achieved this feature with support of hostapd_cli.

hostapd_cli - 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
