I have set up a Raspberry Pi 3 to communicate with the Pixhawk via MAVProxy. When it works, it great, but there are many times where it does not.
When I send commands sometimes, like "wp list" or "mode auto" or "mode manual" etc..nothing changes. I have to say the same command several times before it registers.
Has anyone experienced this problem? Is there a fix?
My ultimate goal is to automate how the Pi sends command via MAVProxy, but if the commands don't register that will be a problem for me (unless someone knows how to get around that).

It seems as if I may have spoke to soon. When turning it on today, the problem seems to be back. However, it occurs less frequently and mainly when using the "mode" command.
When I want to change modes it will ignore multiple times before it accepts. I checked to make sure BRD_SER2_RTSCTS was still set as 0, and it was. I even checked via MAVProxy...
param show BRD_SER2*
MANUAL> BRD_SER2_RTSCTS 0.000000
I tried increasing the baud rate to see if that would help, but still the same issue.
That seems to have helped!!! I had to reboot the Pixhawk after I wrote the parameter and MAVProxy seems to accept everything I send now. Thanks!

So use BRD_SER2_RTSCTS, on the pixhawk that should correspond to Telem2 (I think). The 3dr radio has CTS/RTS so you want to leave it on for that, but usually from the raspberry you just connect rx/tx so turn off CTS.
I have the Pi connected through Telem2, 3DR radio through Telem1, and then I have an Arduino reading data from Serial 4.
Will turning off BRD_SER1_RTSCTS make it so I cannot communicate through the telemetry radio?
I know the telemetry radio is redundant, I just have it for testing purposes right now.

Try turning off BRD_SER1_RTSCTS or BRD_SER2_RTSCTS.
