Hi Tim,
Please see answers to your questions,
You need VBAT at all times for module to work. Cannot leave VBAT open.Should not be a problem.You can leave VCCIO and VCC to OFF and keep VBAT ON. The power draw is 10 uA. It is not advised to keep Vcc = ...
Majority of the use cases you are right, there is no need to send these commands when the module wakes up. It will acquire and track satellites on its own.
However if you want to configure a module and not want to use old ephemeris data (maybe becaus...
In VIC3DA, GGA messages are sensor fusion messages.
If you need pure GNSS message, you can look at PSTMDRGPS message being output. This will output GNSS only fixes.
For this you need to enable CDB-ID 228 [bit 23]

Hi Benjamin,
For LIV4F we can output a 1 PPS pulse. The pulse duration can be changed to 1 us but the the frequency is 1 Hz. To change the pulse duration you can modify CDB 301. The default value is 0.5.
However we have chipsets that can output a hig...
Hi,
For timing applications, I would consider using Teseo LIV3FL.
You can adjust the pulse duration (time from rising to falling edge) of the PPS signal by changing CDB-301.
