Can you upload the code via wifi?
I know I saw the Bluetooth addon post..
If it's not possible, you could easily do a 'transmit to file>crc check on data>retry or proceed> then update'
Not sure if there's enough room as I've yet to receive my unit and don't know how much storage is used between firmware and/or code..

I'm used to crappy networks in my line of work so I always have to figure stuff out like this lol
