I'm thinking of creating a chat app which is similar like firechat. which needs no internet for communication and depends only on BT or WIFI to communicate and also have an advantage of platform independent. I've seen many sites referring some sites like open garden for firechat and alljoyn framework. I really don't understand what this things are for. Its really hard to find a solution for this.
I tried alljoyn initially, but the last update was about 3 years ago. the sample apps crashes in devices. So any one who worked in this kinda project or or sharing some knowledge will be more helpful!
Thanks in advance!
The official website is outdated, use git repo (git clone https://git.allseenalliance.org/gerrit/core/alljoyn.git), a chat is one of the samples.
