"Did you purchase from Witespy? If so I'll contact for an RMA tonight barring some support from them.
Also something I just found out is the 2.8 has a jumper pin set for enable/disable external gps/compass which is what I'm trying to use."

"Was there any resolution to this? Purchased the 2.8 two weeks ago got it a few days ago and tried to calibrate and program it last night, also getting the same regarding the sample but I only get 3 samples."
