RAK3172 2400 baud 8E1

No parity support for uart1. 8E1 does not work at 2400 baudrate on uart2. Serial.begin(4800, SERIAL_8E1 , RAK_CUSTOM_MODE); The data I sent in the command Serial.write(0x10); Serial.write(0x7B); Serial.write(0x01);Serial.write(0x7C); Serial.write(0x16);
the output data is 0x10 , 0xAF, 0x7C, 0xF1.
What I need is 2400 baudrate 8E1 for any serial port to work. Could you help?

Welcome to RAK forum @Lcd ,

RAK3172 doesn’t support baud 2400. RAK4630 supports 2400 though.

However, even RAK4630 support 2400 baud, RUI3 doesn’t support parity configuration.

Thanks Carlrowan. I need to make an m-bus reading from the ultrasonic flowmeter in 2400 baudrate 8E1 format and send the information to the lorawan network, I bought 50 RAK3172s for this job. Any suggestions on how to do this job with the RAK3172?

As far as I know there is no plan to support parity configuration on RUI3 soon. Based on that, it seems you have to use an external MCU and make the RAK3172 a LoRa modem at the moment.

I will still forward this to RUI3 team and update you on any feedback. I also understand the importance of parity configurability.

Thank you very much for the information you provided.
