FAQ - ksiazkowicz/lightbulb GitHub Wiki
This is a frequently asked questions page. I bet nobody reads it anyway, but it's there so I won't have to explain some of the stuff I already explained a hundreds of times all over again and just point you guys here.
1. Would you implement stickers/sending photos/"seen" feature/stabbing people etc. over Facebook?
There are lots of features which Facebook has and doesn't support them over XMPP at all, even though it would be possible, they just don't do it. Supporting all these features would actually require me to spend long, dark and lonely nights coding Facebook API support (which would involve actually doing the client part from scratch all over again) just for few features that I'm not even going to use. I would consider them if I were actually coding a Facebook API client, but it's a XMPP one so Facebook support is an option, not a requirement here, sorry. List of features and limitations available over XMPP with Facebook is available here.
2. I have no idea how to configure Facebook Chat, can you help me?
This thing is actually described pretty well on Facebook and nobody reads it anyway. You need to add an account first, choose "Facebook Chat" in server selector and then fill the rest with parameters from here. If you're using 2-factor verification, you should use application password.
3. I'm getting XMPP_STREAM_ERROR on login, what does it mean?
This error usually means that your account parameters are wrong - so you either have wrong login, password or server details. If it happens in any other situation, report it to me, describing the steps to reproduce it.
4. I'm getting SOCKET_ERROR, God WHY?!
It just means that you got disconnected from the server. It can happen when switching between Mobile Data/Wi-Fi or losing Mobile Data/Wi-Fi connection for a while when using it. Bear in mind that Wi-Fi on Symbian is not exactly the most stable thing known to mankind so having random breakdowns of connection on it is really common - for example, I can't use Lightbulb with my Wi-Fi at home at all.
