i have searched many threads and i am really frustrated. any help will be appreciated.
i am using an apm 2.8 and an external GPS with compass(ublox).i had no problems with uploading the firmware and accel calibration. but in compass i selectected apm with external compass option and i have checked the externally mounted option under (#compass).i clicked live calibration and a dialog box appears with three images which are the axis. now , when i rotate my apm, no points are got as sample. it simply displays
"got +0 samples
compass 1 error:99."
NOTE: i have removed the jumper from the apm as i am using an external compass and gps
i have connected the 5 pin plug from the gps module to the gps socket and 4 pin plug(two are active) to the socket below gps.( i have not used i2c)
and also , in apm , the blue and green led’s are solid but red and yellow led’s are blinking.
in gps with compass module, red led is solid and green led is blinking.
sorry for my bad ENGLISH and THANKS in advance.
