The ConnMan project provides a daemon for managing internet connections within embedded devices running the Linux operating system. The Connection Manager is designed to be slim and to use as few resources as possible, so it can be easily integrated. It is a fully modular system that can be extended, through plug-ins, to support all kinds of wired or wireless technologies.

ConnMan 1.23

BY Patrik Flykt ON Apr 08, 2014

ConnMan 1.23 was released Friday, April 4th, 2014.

With version 1.23, ConnMan now supports the very basics of WiFi P2P scanning. With proper firmware support and latest possible version of wpa_supplicant from git, WiFi P2P networks can be neatly listed from the command line client. For the moment that is all the functionality so far available, further ConnMan releases will support more WiFi P2P capabilities. Another bigger feature in this release is the improved Session policy support, the policy module now has better control of which services to connect or disconnect.

In addition to introducing these two new features, a few important bugfixes have been made. Upgrading ConnMan is therefore recommended. The new WiFi P2P and Session policy module features are limited to their specific use cases and should therefore not cause unnecessary concern when upgrading.

The user visible changes include:

  • Support listing of WiFi P2P devices (Tomasz Bursztyka)
  • Improvements to Session and Session policy modules (Daniel Wagner)
  • Cellular connections via oFono using DHCP for address acquisition now work properly (Jukka Rissanen, Eric Bouxirot)
  • Various bugs with DHCP have been fixed (Jukka Rissanen, Patrik Flykt)
  • Various tethering issues have been fixed (Guoqiang Liu, Patrik Flykt)
  • VPN server routes are now properly removed (Chengyi Zhao)

Thanks for all the hard work and bugfixing go to Chengyi Zhao, Claudio Takahasi, Daniel Wagner, Eduardo Abinader, Eric Bouxirot, Guoqiang Liu, Jukka Rissanen, Marcel Holtmann, Patrik Flykt, Tomasz Bursztyka, BMW, Intel and OpenBossa. A special thanks to everybody on the mailing list reporting issues and testing fixes!
