I am using GPS L70 Module from Quectel,& using the part M20057-1. Link has design details. Currently, I have shorted AT1 & AT2 with 0-ohm res. I feel no Antenna tunning is needed since with the same RF path GPS is working with External u.fl active antenna. What could be a potential issue that am not able to fetch any HDOP, PDOP values or any satellite details from this module. ? PCB Stack-up is fairly simple. with L1-L6 removed GND plane below this module & RF path is 50 ohm Impedance matched.
