Question

asked Nov 9, 2022 by BenH

Is any part of M10578 Test mode a self-test?

The documentation does not explain much about the Test Modes.

Packet Type: 810 PMTK_TEST_ALL

Bit1 TEST_ACQ

Bit2 TEST_BITSYNC

Bit3 TEST_SIGNAL

Are these all dependent on having satellite reception? i.e. is there any self-test capability?

Hi Ben,

All these test commands require satellite reception, there is currently no self-test capability on our modules.

Please see below flow for PMTK commands:

Many Thanks

Steve

OK, thanks.

Is the bitsync when the time first appears in the NMEA stream, before lock is achieved?
