The Quectel GNSS does send out the “UBLOX” specific message. I don’t know if this is standard or the engineers at SEEED hacked the firmware. I do know that I cannot change the data format modes by sending it a message over the serial port. I see the message on the header but I do not think it is wired to the module. But, of course the $GNRMC message is rejected and this is the source of time and date added as metadata in the upstream messages.
