Hey @primeshp
Good question. I thought I configured your boards before they got sent out.
Since the new design utilizes the AUX pin on the nRF9151, you will need to make sure that this command is set followed by AT+CFUN=0 (to save it)
AT%XANTCFG=1
AT+CFUN=0
Let me know if that makes a difference. Both of those boards previously got quick fixes (even, surprisingly, indoors during the day. Though mixed results) Best to make sure you have a clear view of the sky. SUPL will also speed up the process as well. You can use the gps
sample in NFED and enable these options:
CONFIG_GNSS_SAMPLE_ASSISTANCE_SUPL=y
CONFIG_GNSS_SAMPLE_SUPL_HOSTNAME="supl.google.com"
You will need to download and install the SUPL library though.
