@louaykamel does this work for you?

[louaykamel]

@jakubcech the code looks clean, so I suppose it does work, anyway will test it later today to confirm.

[jakubcech]

Did it work the way you need it to @louaykamel ? Thanks :)

[louaykamel]

@jakubcech, @GalRogozinski, It compiles, but wasn't able to receive anything from "sn_trytes",
there is still something missing!

I was able to receive the sn_trytes when testing on my end

WilI finally merge it to next version
Are the bundles coming indeed in order?

Shouldn't be merged until documentation is ready

[DyrellC]

Publish works on my end, just needs the documentation
