Arduino Mega 2560 Client Error connecting to Hexing meter.

Good day.

I have a problem with the Arduino port not being able to successfully connect to the meter.
Using GXDLMSDirector (9.0.2501.1001) there is no problem and I can connect to the meter and read the registers I need. I will add the Log and setting below.

I downloaded the sample files from github and proceeded to try and compile the sketch in the Arduino IDE(2.3.4).
To get it to compile I had to commend out the following section in serverevents.c.
From line 77 - void svr_notifyTrace4(const char* str, gxByteBuffer* value) - to line the end of the file.

After that it compiled without and problems.
Downloaded to the Mega but found that it was trying to send all communication on just UART0. (Meter comms and debug messages.)
I then change the debug UART number from Serial0 to Serial1.
Downloaded again and got the expected response from the Debug UART.

Next I set up client.init to be the same as in GXDLMSDirector
Client.init(true,1,1,DLMS_AUTHENTICATION_HIGH,"00000000",DLMS_INTERFACE_TYPE_HDLC_WITH_MODE_E);

I then connected the meter and got the following from the debug port.
:Start reading
:com_initializeConnection failed 3
:Received bytes: <LF> 37 :Data send failed. Try to resend. 1
:Received bytes: <LF> 74 :Data send failed. Try to resend. 2
:Received bytes: <LF> 111 :Data send failed. Try to resend. 3
:Received bytes: <LF> 148

I added some extra comments to see where it failed.

:Start reading
:SNRM SEND and UA Parsed OK 0
:AARQ SEND and AARE Parsed OK 0
:Start GetAuthentication 0
:com_initializeConnection failed 3

Here’s the HEX log for the Arduino.
