About this Gig
Hello there,
I develop lightweight Linux modem services in C for reliable cellular connectivity and SMS handling on embedded devices. If you need a stable Embedded Linux cellular solution for IoT, smart meters, or industrial products, I can build a custom daemon that manages LTE connection, SMS reception, and modem communication with minimal resource usage.
My service supports Quectel (EG25-G, EC25), SIMCom SIM7600, and similar UART/USB LTE modems. I design clean background services that handle network recovery, logging, and automation so your device stays connected in real-world deployments.
You can get a complete SMS gateway on Linux, MQTT cellular gateway integration, and TCP/IP over LTE ready for production. Solutions run on Raspberry Pi, NVIDIA Jetson, and custom ARM Linux boards.
What I deliver:
- Linux modem daemon in C
- UART modem communication
- LTE connection management
- SMS send/receive gateway
- MQTT integration (optional)
- Deployment guide and customization
Ideal for IoT products, telemetry, remote monitoring, and smart meter projects that need a simple, robust cellular backend.
