Hello,
I am using the Quecte L80R GPS module in a low power application. After sending the “$PMTK161,0*28 standby command, the module enters low power mode until it is awaken by sending one byte over serial after 1 minute. The standby mode works as intended, but the problem I am having is with the fix time. The hardware design guide states that using standby mode keeps ephemeris data to produce a fast location fix, but I am obtaining fix times of 1-2 minutes after each wakeup from standby. I am conducting this test in an open area with no obstructions to the sky, and can rarely get a fix time less than one minute. The v_bckp is connected to 3.3V stable source at all times as well. Is there something I am doing wrong regarding standby mode? How can I achieve a faster fix time after wake up from low power mode? Please provide some insight if you have used this power mode on the L80R.
Thank you
