API proposal for WiFi Direct support
Hey everybody, as mentioned some time ago I am interested in implementing WiFi direct support within connman. In the last week I took some time to go through the specification and try to map the concepts of WiFi direct to the connman DBus API. Attached to this mail are three patches which outline the needed modifications to support group formation (with GO negotiation and autonoumous group support). It would be great if you can take a look at the patches and tell me what you think about the proposal. I tried to not break the API in any part and to build upon existing things. One thing which is missing is the service discovery functional. I am not sure wether this is something which belongs into connman or should be better provided by some other component. regards, Simon ___ connman mailing list connman@connman.net https://lists.connman.net/mailman/listinfo/connman

Hi Simon, I am not completely aware of P2P stuff, so some of my comments might be bogus. Attached to this mail are three patches which outline the needed modifications to support group formation (with GO negotiation and autonoumous group support). It would be great if you can take a look at the patches and tell me what you think about the proposal. I tried to not break the API in any part and to build upon existing things. Technolgy and Service part looks ok to me. The group thing looks complicated: a lot to do in user side. Wouldn't it be possible simplify it? (default group, etc...) It might even be wise to solve the simplest use case of p2p, so without such group interface. Btw, in case a connman device get's invited to connect: how would it be handled? It probably requires agent stuff here. One thing which is missing is the service discovery functional. I am not sure wether this is something which belongs into connman or should be better provided by some other component. Underlying wifi daemon (wpa_supplicant) should handle that. I don't know how much wpa_supplicant supports about P2P though. Br, Tomasz ___ connman mailing list connman@connman.net https://lists.connman.net/mailman/listinfo/connman

It might even be wise to solve the simplest use case of p2p, so without such group interface. A group needs a least one group owner. Thats called a autonoumous group. Peers can connect to a exiting group or connect to another peer to form a new group. So every time you have the abstraction of having a group and have to maintain it.

I don't know how much wpa_supplicant supports about P2P though. Service discovery is implemented in wpa_supplicant but you have to use it. You can register services through wpa_supplicant which can be found by other peers to start a service discovery request to find services of other peers. wpa_supplicant has a quite good documentation on this at [1]. regards, Simon [1]: http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap.git;a=blob;f=wpa_supplicant/README-P2P;h=8447a9044f67f606943729604e741f41bd1c09b2;hb=HEAD#l202 -- Simon Busch - http://mm.gravedo.de/blog/ ___ connman mailing list connman@connman.net https://lists.connman.net/mailman/listinfo/connman
