Develop TWS Cloud-Connected Firmware
Budget: ₹37,500 – ₹75,000 INR
I’m launching a brand-new true-wireless-stereo product and need its entire firmware built from the ground up, with a clear focus on Internet and cloud connectivity rather than the usual Bluetooth-only stack. Your code should let each earbud authenticate, provision itself securely, and exchange data with our cloud services for features such as usage analytics, OTA updates, and companion-app integration.
To make sure we’re aligned, send me a detailed project proposal that explains:
• the toolchain, SDKs, and connectivity libraries you plan to use (e.g. FreeRTOS, Zephyr, AWS IoT, Azure IoT, etc.)
• how you will architect the cloud handshake while still maintaining low power draw expected of TWS hardware
• a milestone schedule from bootloader bring-up to final OTA test build
Acceptance criteria for the final firmware:
1. Successful pairing with our mobile app over Bluetooth LE, followed by seamless hand-off to Wi-Fi (or similar low-power IP link) for cloud operations.
2. Secure TLS communication with our test endpoint, passing predefined API calls.
3. Verified OTA update flow that can roll back safely.
4. Average current draw in connected-idle state within limits we will share at project start.
If you have prior work that proves you can squeeze robust cloud functionality into a tight power budget on embedded audio hardware, your proposal will stand out.
