Introduction - RDK Extender

  • RDK Extender profile is a Yocto based RDK miniature build with opensource OpenSync agent
  • OpenSync agent is cloud agnostic and it forms mesh orchestrated by Plume cloud
  • RPI4 target is chosen for extender profile since this target is chip and widely available
  • Two external Wi-Fi dongles are used for 2.4GHz and 5GHz radio support
  • OpenSync's minimum requirement on the WiFi radio is the support for 2AP and 1 Station interface
  • Conceptually, RPI4 extender can be used with different Gateway devices(which has OpenSync agent). But currently validated with TurrisOmnia RDKB GW
  • Prerequisite: Need to contact Plume to acquiring TLS certificate and backhaul credential

Host Setup

NOTE: Observing fetch errors in VMs with Ubuntu14.x. Thus, suggesting to use VMs with Ubuntu16.x or higher.
