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

Another consideration I just had - Epoch rollover. a once every 20 years event with GPS modules where the 10 bit week number value resets. Its unlikely, but you will see in the RMC message also I think that the date is wrong. Many GPS still work with outdated chipsets but give wrong date ( 1024 wee...

Re: Need an ELI5 on docker

Docker is not Virtualization, you can not run completely different OS, but you can run applications that use the same kernel but uses completely different version of tools and libraries. It has more in common with "linux changeroot/chroot" (IMO) but with more security/isolation between apps/containe...

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

If you also print out the GGA string, and also the RMC strings, you could verify that the position data from GPS are changing. Then you could conclude that the problem has to be somewhere else. https://www.trimble.com/OEM_ReceiverHelp/V4.44/en/NMEA-0183messages_GGA.html https://www.trimble.com/OEM_R...

This whole concept doesn't exist anymore/yet.

How does "taking a sample" work ? You need to send some data TO the device first to get some reading back ? You can not configure the device to just feed you samples at a steady rate ? Do you know how many bytes are transferred while taking one sample ? Is the device powered trough the USB port also...

Re: QSerialBus (Modbus), QTCreator 5 and RaspBerry

On normal debian you have the
- libqt5serialbus5
- libqt5serialbus5-dev

packages, so I assume they also are installable in Raspbian.

( I'm assuming you are using Qt5 here... )

The hard part is the remote access. - I dont know how updates work on OSMC, or if OSMC still is built on top of Raspbian. - So I'm suggesting that probably running Kodi on top of Raspbian Buster gives you the best options/flexibility.
