Hi! I'm using an old laptop (with ubuntu 18.04.1 ) with octave 4.2.2 and

I'm

trying to connect it with an arduino Uno board. (Arduino 1.8.7 IDE)
After running the arduinosetup intruction ( I'm doing this in order to

check

if the laptop can connect to the board) when I try to find the board I'm
always getting an empty string as a result. Any Suggestion?
Thanks.

When running the arduinosetup command, looking on the Arduino IDE, did you
verify the serial port it detected was OK, set the board type correctly and
upload the code to the Arduino, (and was it successful)

If the scan is still failing, what happens if try to create an Arduino
object:

ar = arduino('/dev/ttyACM0')

NOTE: change the /dev/ttyACM0 to whatever the port your arduino is connected
to.

My board is UNO and in the IDE apears Genuine Uno, I guess it's the same.
The upload is succesful and the scanForArduinos function is still failing.

ar = arduino('/dev/ttyACM0')

I've checked that it'is the same port than when I've uploaded the firmware
to the board.

That error suggests that the instrument-control package is not installed
- or somehow not loaded it is is.

Do you have instrument-control and the arduino package both listed when

pkg list

After running the load for arduino

pkg load arduino

If you rerun the 'pkg list' command, the arduino and instrument control
packages should show a '*' next to them to show that they were loaded.

I had the instrument-control package installed and loaded because I could
see the '*' next to the arduino and instrument-control packages, but
probably I had any problem in the installation because I've reinstalled the
instrument-control package again and now everything is working corretly.
scanForArduinos is working , the program to control the servos too.
Thank you very much!!
