Are you sure? You don't have USB? How are you communicating with the
receiver with no serial and no USB?

Everything useful in the logs should also be in the JSON.

No, you don't read the TPV, the TPV is pushed, not pulled.

Yes, it is in the TPV, SKY, etc.

Lost me. What is "it"?

Uh, there is no u-blox UBX-GPSTIME message. Do you mean UBX-NAV-TIMEGPS
(0x01, 0x20)? Nothing in there that is not in the TPV.
UBX-NAV-TIMEGPS is only useful with PPS.
