MavProxy.py "link 1 down" w/ RasPi

(Sterling Ralph) #1

All-
I am trying to control my Pixhawk via MavProxy on a Raspberry Pi 3 B. I have installed everything successfully, enabled serial port hardware so I can utilize the ttyS0 connection.

Every time I run mavproxy.py, I only receive the following:

Auto-detected serial ports are:
/dev/ttyS0
Connecting to /dev/ttyS0
Connect /dev/ttyS0 source_system=255
Log Directory:
Telemetry log mav.tlog
Waiting for heartbeat from /dev/ttyS0
MAV> link 1 down

First, should I be concerned that nothing follows the “Log Directory”. Secondly, I am not very familiar with all the tools MavProxy has to help troubleshoot this connection. What should I start with? (If I append --startup, I can see data, but it is gibberish ie. question marked boxes appear in console).’

Thanks in advance!

Dear Sterling_Ralph,

The Pixhawk connected to Raspberry 3 B hardware from TX/RX/GND, 5V(if Raspberry have its own power, not necessary) and the hardware setting can be easily get from website or google.

Pixhawk connect to Raspberry from Mavlink connected. Please ensure your install is right.
