DLMS CPP library for armv7l

Hi Mikko,

I am using armv7l-analogics-linux-gnueabi-g++ and the version details as below.

root@ubuntu:/home/ckrath# armv7l-analogics-linux-gnueabi-g++ --version
armv7l-analogics-linux-gnueabi-g++ (Timesys 20140729) 4.8.2

Hi Mikko,

Please find below containing the console texts.
Please note that I have used compiler armv7l-analogics-linux-gnueabi-g++.

I can't figure out what's going wrong. Used VS Code IDE and there is no error highlighted on it.

root@ubuntu:/home/ckrath/projects/Gurux.DLMS.cpp-master/GuruxDLMSClientExample# make
Compiled src/communication.cpp successfully!
Compiled src/GuruxDLMSClientExample.cpp successfully!
obj/communication.o: In function `CGXCommunication::WriteValue(GX_TRACE_LEVEL, std::string)':
communication.cpp:(.text+0x80): undefined reference to `GXHelpers::Write(std::string, std::string)'

UPDATE: Now I have managed to successfully compile the cpp library using the toolchain compiler (armv7l-analogics-linux-gnueabi-g++). For now to test, I am using the same example project provided along with the source code (GuruxDLMSClientExample). When tried to read, I got an error as "Read failed. Timeout occurred. SNRMRequest failed 253".

I am trying to read an Indian standard Saral meter. I can successfully read the meter from windows using the same example program.

The command used on linux as below.
./gurux.dlms.client.bin -S /dev/ttyS0:9600:8None1 -c 32 -s 1 -a Low -P ABCD0001

And the command used on Windows as below and read successfully.
GuruxDLMSClientExample.exe -S COM1:9600:8None1 -c 32 -s 1 -a Low -P ABCD0001

Thanks,
Ckrath.

Hi Mikko,

I am using RJ11 optical prob. I have tried all the standard baud rates (300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600 and 115200). The stty command shows details as below.

# stty < /dev/ttyS0
speed 9600 baud; line = 0;
rprnt = <undef>; werase = <undef>; lnext = <undef>; flush = <undef>;
-brkint ixoff -imaxbel

Hi Mikko,

Finally, it was read successfully. There was a serial port issue.
The GuruxDLMS library is working perfectly.

Thank you so much for your support.
