I am looking for a freelancer who can help me with Raspberry Pi RS-485 connectivity for my industrial automation project. The ideal candidate should have experience in developing similar projects.

Intended Purpose:

- The RS-485 connectivity is intended for industrial automation.


- The type of sensors that will be monitored is energy meters (Modbus protocol).

Number of Devices:

- There will be 6-10 devices connected to the RS-485 interface. But for this task we just need to read data from a single sensor.

Skills and Experience:

- Experience in developing Raspberry Pi projects.

- Knowledge of UART/RS-485 connectivity.

- Experience in industrial automation projects.

Specific Roadblock currently facing:

I'm using this board: CM4-ETH-RS485-BASE-B from Waveshare

Board specs: [login to view URL]

Wiki: [login to view URL]

It has four RS-485 ports. Able to see them (ls /dev/tty*). Able to write to them (TX) but not able to read (RX). The board is configured in Semi-automatic mode (using a hard soldered 0R). So we need to be able to switch b/w send and receive modes. Or put one port in Send, the other in Receive and connect these two ports to RS-485 loop (containing 1 sensor)
