FIXED - VeraLite <-> Arduino UNO : USB ACM Serial port configuration fails

[gerardosamara]

Hello,

My project is to connect an Arduino Uno + some devices to my VeraLite ( 7.0.17)  so I have installed the UI7 MySensors plugin (from mysensors.org) successfully but the creation of the device fails :

MySensors plugin : Choose the Serial Port
MySensors Plugin[23] : Running Lua Startup

The problem is in the serial port configuration :

 If you connected the USB/serial device and it's not displayed here, reload Luup.

As per dmesg command , the VeraLite is equipped with USB ACM Device

Note :  The Arduino UNO is plugged directly in the VeraLite USB connecteur , a powered USB Hub does not seem to be required as the power LED is ON

Any advice ?

Assuming you followed the official Vera Controller install instructions then you might want to try the steps I posted on the MySensors forum

[gerardosamara]

Thanks @blacey , I followed the instructions from the link you pointed .

The proposed steps you proposed are not working unfortunately.

NOTE : Forgost to say that "Lua Startup Failure Can't Detect Device" is displayed on the MySensors plugin device

Sounds like you're not running the plugin version from the UI7 branch?

[gerardosamara]

Hi ,

I downloaded the 10 Arduino plugin files from the "Git Repo for UI7"  link of this page https://www.mysensors.org/controller/vera .

[akbooer]

Looking at the file, L_Arduino.lua, from that branch, line #638 shows

Code: [Select]

luup.set_failure(false)

This may cause that error message, since, in their wisdom, Vera changed the calling syntax for this routine under UI7 to take a numeric parameter.

You may find that changing this line to

Code: [Select]

luup.set_failure(0)

will fix the problem.

[gerardosamara]

Thanks akboer ,

I modified the D_Arduino.Lua file in line 636 (false->0) and also in line 501 ( true ->1) but still the device "MySensors Plugin" shows "Startup Lua failure" .

I have also deleted and recreated this Device but still the same

[akbooer]

Ah. So that is different, now.  What errors show in the log file?

[gerardosamara]

Here it is folowing a LUUP restart

From what I know, only Arduino boards with genuine FTDI serial chip (or fake ones with the same id) is recognised by Vera.

@gerardosamara, that looks a lot like the problem I experience after loosing power to my Vera, including the latest Vera 3.  The steps I provided earlier, typically fix the problem and has worked for others.  I would give it another try since you have upgraded plugin.

FYI, the MySensors web-site has been updated to include these troubleshooting steps.

[gerardosamara]

@blacey ,

Thanks for your support to help to solve my problem.

I attempted again with your method but unfortunately  I cannot setup the serial port ( the initial setup )

If the suspected cause is really an Arduino Uno  USB hardware ( USB ACM) which is not supported by the  VeraLite controller  , I will be interested  a confirmation from other users who tested with an Arduino UNO .

[gerardosamara]

Today I issued a support request to Vera who worked remotely to fix this serial configuration problem , as per the enclosed screenshot .... but I do not know what is the fix , and I have asked about it

Now the Device "plugin MySensors" show "Connected to : 31(115200) .

=> 31(115200) is the content of the variable GWAddress


EDIT : What the Vera support said that they synchronized the unit to recognize what is plug on its USB port.

[gerardosamara]

The fix installed by Vera support worked 1 day , now i am back at the beginning ( post#1).

I sent a mail today to Vera support for this serial gateway configuration problem.

[gerardosamara]

Today Vera worked remotely to fix again this serial configuration problem 

Some changes were done in the backend and now the serial port configuration looks fine even if you reload the engine.
The Arduino plugin was not starting because the port /dev/ttyUSB0 was used by a device created by the ALTUI plugin , a 3rd party plugin which is not developed by us.
The device created by the ALTUI plugin was removed and now the Arduino is properly detected by Vera.


Now the Device "plugin MySensors" show "Connected to : 31(115200) .

=> 31(115200) is the content of the variable GWAddress

Note : I have re-created the ALTUI device for the moment ( this a test VeraLite)
