Hi everyone,
I'm reaching out for help because I can't connect my Arduino MKR1010 Wifi to Matlab via the arduinosetup command; I keep getting the following error at the end of the procedure: "Test Connection Failed. Go back to check your settings.".
Over the last couple of days I've tried the following (with no success):
I'm currently using an academic version of Matlab 2020b (I'm a college student), I'm going to try again on Matlab 2019b.
I should mention that the arduino was purchased 2 days ago for that very purpose, and that it works just fine in the Arduino IDE and while connected to a COM-port on Matlab. I don't think there's a hardware related issue with the Arduino.
I would really appreciate your help if you have stumbled upon a similar issue, if you have any piece of advice or idea that I should try out.
Thanks in advance.
Michael

Hi Rohan,
Thanks for your answer. I thought there was some kind of issue related to the MKR1010 so I returned it, and bought a Nano 33IOT wifi (couldn't get it to work either, I ended up ditching the "Arduino support package for MATLAB" toolbox altogether and ended up communicating solely via Bluetooth).
I would still like to get to the bottom of this though; here's the output I get from pinging the Nano after it's been setup by MATLAB:
cmd = ['ping -n 3 ', '192.168.1.119']
cmd =
'ping -n 3 192.168.1.119'
>> [~,result] = system(cmd)
result =
'
Envoi d'une requête 'Ping' 192.168.1.119 avec 32 octets de données :
Réponse de 192.168.1.119 : octets=32 temps=91 ms TTL=255
Réponse de 192.168.1.119 : octets=32 temps=4 ms TTL=255
Réponse de 192.168.1.119 : octets=32 temps=19 ms TTL=255
Statistiques Ping pour 192.168.1.119:
Paquets : envoyés = 3, reçus = 3, perdus = 0 (perte 0%),
Durée approximative des boucles en millisecondes :
Minimum = 4ms, Maximum = 91ms, Moyenne = 38ms
'
Pinging seems fine to me, yet the "Test connection" still won't work.
Neither does the connection.
>> arduino('192.168.1.119','NANO33IOT',9500)
Unable to find Arduino hardware at 192.168.1.119. First argument must be a valid serial port, Bluetooth address/name or IP address/hostname.
I've also tried configuring a Bluetooth device (HC-05) via the arduinosetup, but same story. I've tried with MATLAB 2019b, 2020b and 2021a. As mentionned earlier, I've given up on that toolbox but it's a shame, it could really be useful.
Thanks for your time, cheers.

This issue occurs when the machine's language settings are set to a language other than English. Please follow the steps below to work around the issue:
1. Open 'master.m' class located at 'C:\ProgramData\MATLAB\SupportPackages\R2020b\toolbox\matlab\hardware\shared\hwsdk\+matlabshared\+hwsdk\master.m'.
2. Replace the char vector 'time' with local language wording like '시간' ('time' in case of Korean) in the line "match = regexpi(result,'time=[0-9.]+ms TTL=\d+')" at line 1237
3. The code line after this change should look something like the following:
>> match = regexpi(result,'시간=[0-9.]+ms TTL=\d+')
