Gurux DLMS for Android

Hi,

I want connect the L&T companies meter with the app but I am getting "No Serial Port Error".

Can you please help me out in this.

Hi,

You don't have a serial port on your PC. Change media type to TCP/IP if you try to connect with TCP/IP connection.

No Serial Port Error

Hi,

By default the chipset text is NONE,
and on click on that following are visible:
1) PROFILIC
2) CP21XX
3) CDC_ACM
4) FTDI
5) CH34X

OK. Your converter is using some other chipset. If you connect your converter to the Windows PC and select "Device management" and select your serial port from there. Select "Properties" and select "Details" tab. Then select second dropdown item. It's something like:
USB\VID_17A8&PID_0001\0001

Send this info to me and we'll add support for this chipset.
Send also a link if you know where you have order this Probe.

Hi,

Your chipset is Prolific. It should be selected. Are you using source codes or packet?
Have you made any changes? Select Prolific as chipset. Let me know if you have problems.

No Serial Port Error

Hi,

I am using the source code as it is not make any changes in that.

I am just connecting the Probe with mobile by using OTG cable, is their any issue cause due to this?

But now when I am click on "Read" it gives me an error "Select serial port first"

No Serial Port Error

Hi,

We are also using OTG cable. I don't believe that it's an issue.
If you have source code, can you check what are vendor and product values?
Put breakpoint to isUsing-method in GXProfilic.java

Hi,

I am using "Gurux DLMS for Android" and in that GXProfilic.java is not present.

It is present in "Gurux.Serial.Android-master"....

Hi,

But I am using the "Gurux DLMS for Android" for reading purpose.....

No Serial Port Error

HI,

Yes, In your previous email you said that you have the source codes. Modify Gurux.Serial.Android reference for your local copy.

You can also start Gurux.Serial.Android and check vendor and product IDs in that.

No Serial Port Error

Hi,

I attach the debugger to the method isUsing() but nothing happen.

I also log the value but it is not printing, simply that method is not executing at all.

Then I apply debugger to findPorts() as onClick "Refresh" button this method is executing. But serial.getPorts() method gives nothing. The Post size is zero...
