Hello,

I have question regarding the DLMS.c master for Arduino IDE

1. Is there any documentation for the code what to be and not to be defined in the code or there's a setting to use serial port RS-232 because i need to connect my MCU to The smart meter using RS-232
2. Is it safe to directly connect MCU to RX TX GND of smart meter?

Thank you in advance.

Hello,

Hello,

1. You can start from here: https://www.gurux.fi/Arduino
The Arduino example is already using RS-232.

2. You need to check that your UART power levels are the same on the MCU and the meter.
