The focus of this release is to bring support for Wireless Endpoints to the Tcl API.

Wireless Endpoints support

The wireless Endpoint API is now enabled in the Tcl lower-layer API. All new features of the Wireless Endpoint / Meeting Point version 1.1.0 are supported:

  • IPv4
  • IPv6
  • Frame blasting: streams and triggers
  • Statefull TCP
  • Latency measurements

For more information, please check our documentation of the WirelessEndpoint.

These features require ByteBlower Meeting Point >= 1.1.0 and Wireless Endpoint >= 1.1.0
