Hello Riccardo,
Thanks, a good point I will be sure to bear in mind! I have further
info so will copy paste what i posted to the "Time Nuts" forum in case
it helps anyone else.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Ublox M8T is now fixed! For future reference this is what was
wrong. CSG Shop ship various versions of this GPS module on a generic
board, as far as I can tell, and reading between the lines. Some
versions need this jumper across two of the three normally bare solder
pads. Mine seems to have "escaped" with a Neo_M8T but the jumper
soldered in place needed for NEO_M8L and NEO-M8U modules. Upon
removing it the device now outputs under control of the current
release of U-Centre software on TP0 and TP2. If anyone wants a photo
of how the pads should be for the M8T I can take one and link here.
But basically the M8T module should have NO jumpers across the three
pads on the reverse side of the board...A learning experience I could
have done without, but at least I have learnt something and it can now
be cased up :) Thanks to all for help here and by direct e-mail.
