Hi, i just read a topic about this which was closed.
I have the same issues, 1 meter range with the 433MHz telemetry and it only connects intermittently. I am using the 3DR radio absolutely stock.
Ground station is a Acer Aspire One with an Intel Atom processor.
Any ideas? Its really annoying my quad keeps falling from the sky as i have no idea on what my batt voltage is!
I can confirm that shielding helps. Using a USB 1.1 hub didn't help at all.
I got the noise levels down to 40-50, but that's still too much compared to remnoise which is in the 20-30 range.
Are your 3dr radios connected to your laptop via a FTDI cable or is it one of those units with the USB connector on the board itself ? I think ive seen before that the later is bad for precisely the reasons you seem to be discovering.
Ive been having problems with these since yesterday (but before i have them for basic tuning in a room and not lost any signal)
Currently the green light is blinking indicating it is looking for another radio. I can get it to stay solid, but thats with the remote very close (30cm), if i move the remote away by 10cm then it looses connection.
Hi, i've got the same issue, as have others:
