I'm transitioning a GNSS tracking firmware from the nRF9151DK to my custom board using SDK/toolchain v3.0.2.. On the DK, I get accurate location fixes, but on the custom board, I only receive latitude: 0, longitude: 0 despite having an integrated GPS antenna. The firmware is identical, and the issue persists outdoors with clear sky visibility. I suspect hardware differences but need guidance on potential root causes. Is there anything that I'm missing that could be causing this issue?
