that is exactly my problem -- it doesn't work at all -- most of the time
even GPS time is not acquired after tens of minutes being waited.

just in case -- got account on online assist for ublox, used python
script from online with my account info and lat/long -- no change.

is there any more lower level way to troubleshoot GPS (sending/receiving
expected input etc) than just eye balling stream of outputs from
