RE: Re: [Paparazzi-devel] LEA-5H Module Freeze after 30 seconds

Hi Martin,

Very good to know. Maybe Paparazzi does something with this at 30sec and 
freezes the tunnel and not the LEA-5H freeze? I just saw u-center stop 
responding but that could have been the LPC freeze not the LEA-5H.

This is a good example where not having the option in software for NMEA is 
going to be a problem. LEA-4P will not be available forever. This is why I 
chose to test the LEA_5H.

Can I help in some way?

the 4->5 migration application note
http://www.u-blox.com/customersupport/ublox5_doc.html says that the
current LEA-5 software has "No UTM (Universal Transverse Mercator
Projection)." This is probably not related to that 30s issue but means
that we need some conversion for Paparazzi.
