OTA upgrade

[buttim]

Since most boards have a very fragile USB connector this would be a real life saver in case it stops working

Hi Buttim,
MySondy Go bin is bigger than other softwares.
MySondy Go is more complex than other softwares.
To have enough memory space, the OTA functions are not available.
In order to have the OTA function, the application must be 1Mb while MySondy Go is 4 Mb.

I hardly see how. 75% of the bin is made of 0xFF runs, so the actual firmware is roughly 1MB, which leaves plenty of space for OTAs
