posix implementation about esp-homekit

[maximkulkin]

If you have a luxury of running a Linux based system, you can use a much more decent and Linux-ready implementations, e.g. https://github.com/KhaosT/HAP-NodeJS or https://github.com/brutella/hc.

Not desktop Linux, embedded mips (no golang) with 4mb flash (no gnome libs or JavaScript).

We're almost done porting. But it's quite ugly due to the different threading stuff. Have a look at https://github.com/korhalio/esp-homekit at let me know if you'd still take it. Well clean it up then.

@maximkulkin we're done i think but my test iTHing doesnt accept the characteristics. any idea where I broke it?

It looks like there was a bug in json library handling var args on buffer boundaries. I just pushed a patch. Please update and see if it fixes.

thanks! we got it working on x86 but not mips. this the output on the mips machine.
mips is big endian, so might be something about endianness?

[aep]

got it. it must be json_write(json, "%lld", x); in json_integer

[maximkulkin]

I see all your aid and iid attributes being zero. Not sure if this is related to printf format.

[aep]

yes it is. using %lld instead of %ld fixed it. I got it running on a tplink hs110 now :)

[user623523]

This is awesome, I love having a posix implementation!
This means I can integrate HomeKit with my home automation system, without relying on nodejs based stuff.
I added another file descriptor in server.c to communicate events from my home automation system into esp-homekit, and that works fine.

Anyway, thanks guys, keep up the good work!

[aep]

Cool! But we're not maintaining this fork since it's rather messy. Instead we started implementing the whole thing in rust . https://github.com/korhalio/hap-rs

[user623523]

I'm sorry to hear that, rust is a no go for me.

maximkulkin: Let me know if you need a bit of development resources put into this, I'll do what I can.

[maximkulkin]

@user623523 Just to let you know, I do not plan to port it to POSIX in the near future. Currently I'm working on ESP32 port and maybe later I will look into Arduino port (where ESP8266 is used as WiFi module), but no other plans so far.

I am done with ESP32.
