HITL with voxl 2

For 3.3v J18 jst port which port of ftdi cable should be used, CTS# or RTS# ?
@Tamas-Pal-0 For UART it is just GND, TX, and RX

@Eric-Katzfey you mean we only have to connect 3 pins in j18 port ?

@Tamas-Pal-0 Yes, the fourth pin is power and we don't want that one.

Is there any way to verify that FTDI cable is connected properly with J18 port ?

@Tamas-Pal-0 The easiest way would be to recompile the modalai_dsp PX4 driver to add more debug messages. But if you aren't comfortable with that then we'll need to come up with something else.

How to do that? Is there any other way to this ?

@Tamas-Pal-0 The simulator will be sending heartbeat messages out over the serial cable. You can use the
screenprogram to see if anything is coming from voxl 2 in the serial cable. -

@Tamas-Pal-0
screenis just a standard Linux program. There are many ways to check the output of the serial port. To start, you could always just docat /dev/ttyUSB0and see if anything is coming out. This post shows how to get a hex dump: https://superuser.com/questions/1402386/view-serial-device-output-in-console-in-hex -
The problem is solved. The problem was with ftdi cable. Thank you for your valuable inputs

@Tamas-Pal-0 Excellent! How were you able to determine that it was the cable?

@Eric-Katzfey @Tamas-Pal-0 For future users troubleshooting HITL setup, I was having the same issue as above. This cable would not allow me to set the latency or share data with the VOXL 2 through J18 port, but this cable works as intended.

@Taylor-Presley Right. Some cables work some don't.
