Re: Ublox Neo 6M GPS module not changing coords.

I just check and if you stay with Google earth, it can use Decimal Degrees. So you only need to record msg.latitude & msg.longitude (Same as Google maps) You don't need to split and combine. https://support.google.com/earth/answer/148068?hl=en EDIT simple test program for you (another one, this is p...

Pynmea2 has been working fine for me for years, with ublox6 and ublox8 The 'shrink' problem is something else, I've seen it but can't remember what it was. It's something like using the wrong style of coordinates. Google maps should be able to take the one supplied with no problem. The batter just h...

Re: Pynmea2 output Decimal Degrees.

I'm a bit lost in what format you want but For example, latitude and longitude properties exist as helpers to access the geographic coordinates as python floats (DD, "decimal degrees") instead of the DDDMM.MMMM ("Degrees, minutes, seconds") format used in the NMEA protocol. latitude_minutes, latitud...

In the future, look at switching the Pi to 'standard' IP address alocation (dynamic) so the Router gives them the IP address. Then in the router, reserve an IP address to that Pi. It will always be given the IP and you control it all from one place. the router. For extending, I find Powerline extend...

Re: Python in Raspbian Lite treats input() as a number.

As above, use Python3.
You fallen on the very very common confusion with having to type python3.

Though take what you have learned with you. If/when you come across Python2 only code.

If xz is part of tar, then it is natively supported in Windows10 too.

Re: why xz format not used for distribution of raspbian images

It'll be the decompression times that are the important one, how long will we have to wait to get our image.

compression times are only relevant for RPT making the image that one time.

I think the only thing we have is the Shmoo setting. If you understand that you may be able to move the timing and voltage envelope to something tighter.
