Deep Tech Specialisation

Zero-Failure OTA Updates

A failed firmware update can brick a device and destroy brand trust. Shardhan's OTA framework is engineered from the ground up for 99.9% success rates across millions of devices.

  • Delta-Update Compression Sends only changed bytes, reducing OTA payload by 60% and saving battery/mobile data.
  • Auto-Rollback Engine If an update fails mid-process, the SDK immediately reverts to the last stable firmware partition. Zero bricking.

Hardware Meets Cloud.

Shardhan bridges the gap between low-level embedded silicon and highly concurrent cloud infrastructures. Whether you're building medical telemetry devices requiring micro-watt power consumption or industrial PLCs feeding high-frequency MQTT streams, our engineering team manages the entire stack.

  • Custom BLE 5.3 Stacks. Proprietary throughput profiles optimized for ultra-low latency bridging.
  • Hardware Root of Trust. Secure boot, encrypted firmware storage, and mutual TLS device provisioning.
