How to create a valid firmware packet to update

[MiguelIrusta]

Hello everybody here,

This is my first time developing for pineTime, this is my code (over 1.10.0)
https://github.com/MiguelIrusta/InfiniTi...leezScreen

I have tried with this https://github.com/InfiniTimeOrg/InfiniT.../README.md

But when I try to update siglo or nrfConnect in android starts and then it disconnects or puts my pineTime blocked in Firmware update 0%.

Can you help me? is something I am missing out?

Many thaks and sorry for the disturbances,
Miguel.
