how can we use that library

[fixajteknik]

my circuit diagram is an esp32 s3 connected Serial1 to rak3172 wisduo board of Serial1. I can send data over UART each others . But I couldn't get your library to work in this setup. what should be prepair first?

1. which code should be in rak3172
2. your this https://github.com/beegee-tokyo/RUI3-Arduino-Library/blob/main/examples/RUI3-AT-OTAA/RUI3-AT-OTAA.ino I am testing, I thing it should be installed in esp32 s3
3. connection diagram?

On the RAK31723 Evaluation Board, AT commands work only over the USB (== UART2). If you need UART1 (ATTENTION UART1 does not work in low power mode) you have to explicit enable it with Serial1.begin(115200, RAK_AT_MODE);

can you show me a simple example such as at+ver=?. how can I get version of rak module with in code. thanks

[fixajteknik]

yes I understand thanks. esp32 should send the at commands over the serial1
