I am trying to use scratchx with a NUCLEO-L476RG borad.
I have followed all instruction I can find, and the borad is recognized by the Arduino IDE.
Then I choose L476 StandardFirmata, and dowload is ok.
If I reset the nucleo here, I can see the string StandardFirmata.in in my tera term.
After deconect tera term, I open the following page
http://scratchx.org/?url=http://khannin … tension.js
Here the fun is starting……
By opening the javascript console, I can see that there is a scan of the com ports.
COM1… COM4….COM9 – here is mine.
Then it is detected as folowing appears on the console:
Querying COM9 capabilities
Querying COM9 analog mapping
But then the port scan is continuing, for some reason, in an infinite loop.
Then I load Blink-Nucleo-l476.sbx project.
Here I get the following error in arduino_extension.js file:
in line 521 : device.set_receive_handler(null);
Unable to get property ‘set_receive_handler’ of undefined or null reference
I am using Win7 machine, with IE11.
Is anyone has already encounterred such behave ?
I will appreciate any suggestion 
Sirma
http://firmata.org/wiki/Main_Page#Firmata_Test_Program
I am loading the Firmata from Arduino IDE, the one belong to Examples -> Firmata (Examples for nucleo L476RG section) -> StandardFirmata.
Do I have to do something else ?
I am checking with the Girmata_Test_Program.
Sirma
By running Firmata_Test_PRogram, I am able to light on/off the nucleo green LED.
So I guess it works well, and uart link is ‘stable’.
Could it be possible that the javascript behave differently than the test program ?
Sirma
Under the javascript console, i can catch following message, when error occurs:
SCRIPT5007: Unable to get property ‘set_receive_handler’ of undefined or null reference
File: arduino_extension.js, Line: 521, Column: 7
It does not ring the bell for me 
Sirma
Here is what I can catch:

It looks good unitl the last ‘F0 79 F7’ Then something goes wrong, but I habe no idea on what could goes wrong
Sirma
To do this Chrome test, I need to spend some time to pass over that restriction
So for the time being, I am not able to test with Chrome.
Sirma
No I am fighting to make the javascript to recognize the Nucleo board.
So far the board looks not connected (or is not recognized by the plugin).
Sirma
I have same behave with Chrome….
The console view give the following logs:
Attempting connection with COM1
arduino_extension.js:508Attempting connection with COM4
arduino_extension.js:508 Attempting connection with COM1
arduino_extension.js:521 Uncaught TypeError: Cannot read property ‘set_receive_handler’ of null

arduino_extension.js:508 Attempting connection with COM9
I load the arduino_extension.js page, then I immediately load STM32 blink project, and I get this uncaught error.
This is followed by an infinite loop on all com ports.
I am contuing…..
If anyone has some suggestion or idea, I will appreciate it
Sirma
Under IE, the com is detected, but straigth ‘deconnected’.
Under Chrome, I observe the same behaviour.
After IE or chrome test, the Nucleo is sending non-human datas on the uart. I can see by connecting tera term on the com port.
When I reset the Nucleo, and connect tera term, I am able to see the string StandardFirmata.ino
When I test with firmata_test.exe, I am able to switch on/off the green led
Could it be possible that I have some browser settings that prevent me to use the com port from the browser ?
I searching in that way… hope Google is my friend.
Sirma
I change com port properties -> Port settings: 115200, 8, N,1
Magicaly it works with IE.
Then I try to make it happens with Chrome.
The funy things is that I can see the reset string sent to the Nucleo (F0 79 F7).
As the string in return is not read, reset string is sent several times, without succes
So it looks that I have some problem with Chrome plugin… some com port read right access ?
… continuing
Sirma
This morning with IE, without changing anything, it fails
Here is waht I can observe on the UART:

It looks the PC host is sending several reset commands.. weird
I am a bit puzzled
Does anyone has some thought ?
I will appreciate any guidance/suggestion
Sirma
This sounds great
How do you move to process ?
Could you guide me how to do so ?
Thanks
Sirma
However it return the following error: Microsoft JScript runtime error: ‘Uint8Array’ is undefined
How did you rid out of this ?
Thanks for your help and suggestions
Sirma
