Pixhawk initial setup not working in new mission planner

Was using 5 mo old pixhawk and updated mission planner software. I can’t get the pixhawk to calibrate accelerometers or get a GPS lock to arm the system. It also keeps giving me a bad AHRS message. I purchased a brand new pixhawk thinking I had faulty hardware…same exact issues with the brand new board out of the box. Mission planner wont calibrate the compass also…it won’t even pick up that the compass/ GPS is there and moving in circles. Brand new GPS also…all purchased through 3dr.

Anyone else having same issues? Is it mission planner or arduplane 3.5.3 that is causing the issues??

what version of Mission planner are you running?
