Interesting!
You can also dynamically change the Bluetooth device name within one discoverable session, and that seems to be able to be the full 248 bytes indicated in the API docs (at least testing between Moto E and Nexus 7). On the discoverer side, you can continuously trigger discover sessions (which seems to be about 12 second long) without issue, and you will see the updated names as they occur. All in all, it seems like using Bluetooth this way, while a total insane hack, is viable and creates a very simple messaging system on top of which we could easily run OTR or Axolotl. I am thinking of wrapping this up in the ChatSecure UI since we have the pluggable protocol piece anyhow. Groupchats would be unencrypted messages based on #topic but you could also init one-to-one chats with specific devices as well, and OTR would work in that case. +n _______________________________________________ Guardian-dev mailing list Post: [email protected] List info: https://lists.mayfirst.org/mailman/listinfo/guardian-dev To Unsubscribe Send email to: [email protected] Or visit: https://lists.mayfirst.org/mailman/options/guardian-dev/archive%40mail-archive.com You are subscribed as: [email protected]
