Hi fnoop, thanks for your help.
It worked after replacing “ttyama0” with “serial0” ^^
Hi fnoop, thanks for your help.
It worked after replacing “ttyama0” with “serial0” ^^
I googled on Rpi3 serial port and it said ttyAMA was changed to serial0 ^^
Hello all, I have followed the exact procedure steps that you have done, But am not able to get reply from pixhawk.
I enabled uart connection and disabled bluetooth also. i got this same output as @Kyomo_Jung .
I had a load of trouble with this as well.
Turns out that the APM2.6 has a AutoMux. which means that UART1 is shared with the USB port. So if you power the APM via USB (which i normally do from the computer) then the Telemetry port 1 does not provide mavlink.
I did all the above with a raspberry Pi Zero W and couldn’t get it to work, until i powered up the APM up using a battery and not the USB port. It then started to work.
I’m now looking at finding out how to enable the second telemetry port or removing this behaviour!
@Kyomo_Jung Hi, i’m try but still not working, this is my configuration:
i try with S0 too, but nothing happens
‘MAV> Waiting for heartbeat from /dev/ttyS0’
The first connection what i did was this
But then i read what i need use a logical level converter and now i’m using one, but still not working, please help me, i’m trying about 5 days and nothing
When you want to use telemetry port 1, you need to unplug the USB and power it from battery.
I’ll post my config on the raspberry-pi zero a bit later
Here’s my config on a raspberry pi zero W.
I use /dev/ttyAMA0 as i have the connection on the first few header pins as shown on:
In the rasp-config, i have serial login shell DISABLED and serial interface ENABLED.

Please note:
What OS are you using?
I’m using Ubuntu mate 16.04, but still not working
Rasberian Jessie. The standard debian image they provide.
Funny, i actually didn’t type commands in the console. I didn’t test that!
I only tested connecting mission planner to the MavProxy. I can have a try at this next week, if you want!
Yes please, thank you so much
Hi,
param show ARMING_CHECK does give a response to either, but then I connected mission planner and it suddenly showed:
Received 306 parameters
Saved 306 parameters to Drone450/logs/2017-09-07/flight3/mav.parm
After this, the command ‘param show ARMING_CHECK’ did work.
There is also a ‘param fetch’ command, but that doesn’t do anything. that seems like a bug.
i use via GPIO to connecting Raspi and Pixhawk.
And I use Telemetry to connect with Pixhawk and Mission Planner.
Raspi power is from USB
and Pixhawk power is from Battery
Could you teach me how to use “ls / dev” to know the port?
Teach me how to type it in Raspberry’s terminal, please
in order to scan port services you can type
sudo screen “port_name” 57600
thankyou antpoli and everybody for your response
hi,may i know how you solve this? i am facing the same problem now…
I created a pdf of what i did on my raspberry pi 4-b to install mavproxy please check out that
what_i_did.pdf (516.5 KB)
then by cloning from github
but whrn i run commands
nothing
Please guide me from starting step by step
