I am setting up the M4 and was working on the GPS... I have the 15db 10mm Taoglas, where I replaced the (very) short u.fl connector with a longer cable to be able to mount it somewhere useful. I carefully tested signal and ground connections, so I am fairly confident I didn't screw anything up.
Unfortunately it can not get a lock with the GPS. I used the 35mm version from the AQ6 and it aquired a 3d fix within 20sec. So the M4 is working ok.
Q1: I replacing the cable an issue?
Q2: How can I test if the Taoglas is working to find out a potential issue with the HW?
Q3: Are there specific software settings i can change (baud rate) to promote a lock?
Any advice is appreciated...
