Industrial IoT Gateway Firmware for Multi-Protocol PLC Data Ingestion and Cellular Telemetry
Pain Points (Public)
Industrial monitoring deployments frequently struggle with heterogeneous legacy PLCs communicating over disparate RS-232/RS-485 interfaces and non-standard protocols, making it challenging to reliably aggregate data on resource-constrained microcontrollers and transmit it over cellular networks without connection drops or buffer overflows.
Suggested Approach (Public)
Design modular embedded C firmware for Renesas microcontrollers that implements asynchronous serial polling for multiple PLC protocols (including Modbus and custom framing), formats telemetry payloads, and manages Quectel cellular modems via robust AT command supervisory logic and TCP/IP sockets for resilient cloud reporting.
