Re: RPI_GPS_ADD-ON_V2.0

PPS is a standard function of some GPS chip sets, not peculiar to the Neo used in the Itead board, but having PPS available on a gpio pin pin rather than on one of the UART control lines, is only common on the Pi, and makes them an unusually good platform to create a reference timeserver. I did not ...

Re: RPI_GPS_ADD-ON_V2.0

You need the hardware serial controller for reliable operation of the GPS function. In theory you can enable Bluetooth on the software serial interface, as was done for Pi's before the 3B+, but it's going to be less reliable than the default hardware set up on the Pi 3B+, and I don't need Bluetooth ...

Update multiple users to pixel

I have a Pi 3 running nicely on pixel after a normal update.

However there are multiple users on the pi and only one user has been updated.

Is there a standard process for replicating the desktop across multiple users ?

To the original poster, whatever licence you choose, consider how it covers your own liability.

Re: Wheezy + Jessie new style static IP question

On more complex set ups the "traditional" syntax is much more usable. you can have multiple named interface definitions, and switch between them using the proper syntax to ifup and ifdown. Copes with multiple interfaces as well. Not every PI connects in only one network configuration. Sadly the pres...

It has the same GPIO header as the other Pi's, just no connector soldered to the PCB.

Sad to hear that Pi Zero will remain difficult to obtain. I'm impressed by its cost, but even more impressed by its size and simplicity. It's potentially a very neat controller for the various PI hats out there. I'd happily accept a modest increase in the price to support that functionality as stand...

Re: Pi network services stop

There is no certainty that the issue is inside the Pi.

You could run tcpdump on the pi and see what is actually passing on the Pi's interface.

Investigate the resulting capture using wireshark on the Pi.
