build LoRaWAN device with RTC sync, relay output and status LEDs

Building a reliable LoRaWAN node is more than just sending a ping. If you want a device that actually stays synced and handles real-world tasks like switching relays, you need a solid firmware foundation. Most people struggle with time drift or missed downlinks, but I focus on making sure the RTC sync and local logic work even when the gateway is out of reach.

I develop custom firmware for LoRaWAN devices (STM32, ESP32, or Arduino) that includes precise time synchronization and hardware control. Whether you are using TTN, Helium, or a private ChirpStack server, I ensure the payload is lean and the connection is stable.

Service Included:

- LoRaWAN stack configuration (OTAA or ABP)

- RTC time synchronization for accurate logging

- Relay control logic and scheduled switching

- Status LED indicators for network and hardware

- Payload formatter for TTN/ChirpStack

- Power optimization for battery longevity

How it works:

1. We discuss your hardware and pinout requirements

2. I write and test the firmware on my dev boards

3. I send the source code and flashing instructions
