BITWORX Firmware Update Platform

The BITWORX Firmware Update Platform is a comprehensive solution for managing over-the-air (OTA) firmware updates for Arduino and ESP32-based microcontrollers. Our platform eliminates the need for manual programming and enables remote deployment of firmware updates to devices in the field.

🔒 Secure by Design

End-to-end encryption, digital signatures, and integrity verification ensure your firmware updates are tamper-proof and authentic.

⚡ Zero-Touch Updates

Devices automatically check for and install updates without any manual intervention, keeping your fleet current and secure.

🌐 Remote Management

Deploy updates to devices anywhere in the world through our cloud-based management platform and REST API.

How It Works

Our platform operates on a simple yet powerful principle: make firmware updates as easy as pushing code to a repository.

1

Develop & Build

Develop your firmware using Arduino IDE or your preferred toolchain. Build and compile your code as usual.

→

2

Upload Firmware

Upload your compiled binary to our platform via web interface, API, or CI/CD pipeline integration.

→

3

Automatic Distribution

Devices automatically check for updates and download the latest firmware when available.

→

4

Safe Installation

Firmware is verified, installed safely, and devices continue operating with the latest version.

System Architecture

Our platform consists of several key components working together to provide reliable firmware updates:

Cloud Platform

Firmware storage and management
Device registration and authentication
Update scheduling and distribution
Analytics and monitoring

Device SDK

Arduino library for easy integration
Automatic update checking
Secure download and verification
Safe firmware installation

Management Interface

Web dashboard for monitoring
Firmware upload and management
Device fleet overview
Update deployment controls

Security Features

Security is at the core of our platform. We implement multiple layers of protection to ensure your devices and firmware remain secure:

🔐 Authentication & Authorization

Every device requires a unique access token for authentication. Tokens can be revoked or rotated as needed for enhanced security.

🛡️ Digital Signatures

All firmware is cryptographically signed before distribution. Devices verify signatures before installation to prevent tampering.

🔒 End-to-End Encryption

Firmware transfers are encrypted using industry-standard protocols to prevent interception and unauthorized access.

✅ Integrity Verification

Checksums and hash verification ensure firmware hasn't been corrupted during transfer or storage.

🔄 Safe Rollback

If an update fails or causes issues, devices automatically roll back to the previous working version.

API Reference

Our REST API allows you to integrate firmware updates into your existing workflows and CI/CD pipelines.

Upload Firmware

POST /api/upload

Upload a new firmware binary to the platform.

curl -X POST https://espupdater.runasp.net/api/upload \
  -F "filename=myfirmware.bin" \
  -F "token=YOUR_TOKEN" \
  -F "platform=ESP32" \
  -F "file=@firmware.bin"

Get Device Status

GET /api/devices/{deviceId}

Retrieve the current status and version of a specific device.

Deploy Update

POST /api/deploy

Deploy a firmware update to specific devices or device groups.

Troubleshooting

Common issues and their solutions:

Device not checking for updates

Possible causes:

WiFi connection issues
Invalid or expired access token
Incorrect firmware filename in code

Solutions:

Verify WiFi connectivity and signal strength
Generate a new access token
Ensure firmware filename matches exactly

Update fails to install

Possible causes:

Insufficient flash memory
Corrupted firmware binary
Incompatible platform selection

Solutions:

Check available flash memory
Re-upload firmware binary
Verify correct platform is selected

Best Practices

Follow these guidelines to ensure successful firmware updates:

🔧 Development

Always test firmware on a small subset of devices first
Implement proper error handling and logging
Use version numbers in your firmware filenames
Keep firmware sizes reasonable for your target platform

🚀 Deployment

Use staged rollouts for large device fleets
Monitor device health after updates
Keep previous firmware versions available for rollback
Document changes between firmware versions

🔒 Security

Rotate access tokens regularly
Use strong, unique tokens for each device group
Monitor for unauthorized access attempts
Keep your SDK library updated
