Just bought a SIK radio and trying to connect it. Problem is that i “lose” GPS when i connect SIK radios to my navio2 and introduce the -D switch. I never get fix, and gpshdop 99,99 and satcount 0.
And i got this message in MP (wich i think i never saw before): “GPS 1: detected as u-blox at 115200 baud” even though the serial is configured to 38400
aha, i do have a 433 Mhz… Do they cause interference because they are powerd by the rpi, or is it noise on the GPS signal? Any suggestion for shielding? I have sn-cu shield laying around?
Will it help switching from the usb interface to the 6p connector and a cp210x?
I’ve got remnoise of 75-85 with a mean of 78, and noise at 65-70.
I tried with the sn-cu tape around the SIK radio on the drone, but didnt improve gps. Tried shielding the navio2 gps antenna with a aluminium plate, but didnt help.
What is wierd is that the reach rover unit have OK signal with its shield (10 cm plate).
Another thing i noticed was that in MP under the “messages” tab this message popped up each 30 sec “GPS 2: detected as ERB at 38400 baud”. Usually it only show once each restart.
