External Mode Open Protocol Connect command failed

103 views (last 30 days)
Hello, everyone
And i want to follow last examples(HITL).
I followed at task 2. and I did click Monitor & Tune button.
This error occurs.
The directory has only english.
I don't know why broken word appear.
What's the problem?
P.S. The example says connect serial 4 of pixhawk 1. and I have pixhawk 4.
I think serial 4 port of pixhawk 1 equals UART&I2C B port of pixhawk 4.
Is this right?

Hi,
As per the official documentation, the port named "Serial 4" exists only on Pixhawk 1 and not on Pixhwak 4. The example illustrates how to use a Serial port on Pixhawk to use for External Mode and provides example of Pixhawk 1. For Pixhawk 4, you need a separate serial port. As per documentation, you can use TELEM1 or TELEM2 port on Pixhwak 4 or External Mode which correspond to port lables /dev/ttyS1 or /dev/ttyS2. The port label is important as you need to configure the baud rate for this port in configuration instructions

Hi, Thanks for your answer.
I thought
  • UART&I2C B
  • Telem1
  • Telem2
ports are equal.
but it's not. It can be connected with only Telem2.
Thank you.
