Test Connection Failed Arduini MKR1010 WiFi via Matlab Support Package for Arduino

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):

• updated the Wifi Nina firmware to 1.2.2 (I've also tried the 1.2.1, which didn't make any difference so I came back to the latest version, the 1.2.2). Source: https://fr.mathworks.com/help/supportpkg/arduinoio/ug/board-specific-issues.html
• tried on a different LAN than my household's; with only my computer and the Arduino on the router, while respecting the default Gateway and the subnet Mask mentionned in following tutorial: https://fr.mathworks.com/help/supportpkg/arduinoio/ug/configure-setup-for-arduino-hardware.html
• both static and dynamic IP fail the connection test; even though the Arduino responds to my pings

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.

Hi Michael,

Can you confirm if you can successfully ping the board after it is programmed from the arduinosetup screen?

Can you please share the output of the following commands issued on the MATLAB command window?:

% address is the IP address of the device. Provide the address as a char vector
>> cmd = ['ping -n 3 ',address]; 
>> [~, result] = system(cmd)

Please share the output of the 'result'

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=4 ms TTL=255

     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+')

This issue is fixed in R2021b.
