Customer Overview

The customer develops IoT-enabled fire safety systems in which a Fire Panel Gateway acts as the bridge between on-site fire alarm panels and cloud-based monitoring platforms. This gateway enables secure provisioning, remote monitoring, and real-time alerting for mission-critical safety infrastructure.

Challenge

Validating the Fire Panel Gateway’s BLE provisioning flow posed multiple real-world challenges:

  • The gateway required a physical button press held continuously for exactly 30 seconds to enter BLE configuration mode — even a one-second deviation caused failure.
  • The button press had to align precisely with LED feedback on the device and the mobile app’s BLE scanning window.
  • The mobile application had to securely pair with the gateway, validate connection stability, add the device to a Site, and complete network provisioning.
  • Executing this complex, multi-step workflow manually was error-prone, slow, and difficult to repeat consistently for regression testing.

In short, both hardware and mobile software needed to be validated in perfect synchronization — something manual testing could not guarantee.

TestBot Solution

The team used TestBot to automate the entire BLE provisioning lifecycle by combining custom hardware test jigs with its agent-based automation architecture, bringing physical and digital validation into a single coordinated framework.

TestBot delivered three key advantages:

  • Hardware–Software Synchronization: The TestJig Agent ensured button presses and LED states were perfectly aligned with mobile app actions.
  • Deterministic BLE Automation: The Mobile App Agent handled discovery, pairing, and configuration reliably across every test run.
  • End-to-End Validation: From physical trigger to “Configuration Successful” confirmation, the entire flow was validated as one continuous system-level test.

Key Testing Areas Covered

  • Hardware Trigger: Automated 30-second button press using the TestJig Agent.
  • LED Feedback Validation: Real-time monitoring of gateway LED states to confirm BLE configuration mode.
  • BLE Discovery: Mobile App Agent scanning and detecting the Fire Panel Gateway.
  • Secure Pairing: Programmatic Bluetooth secure pairing.
  • Connection Stability: Validation of BLE link before device addition.
  • Mobile Provisioning: Entering network credentials and applying configuration parameters.
  • End-to-End Workflow: Full validation from button press to successful configuration.
Hardware Integration

A custom TestJig was integrated with TestBot to simulate physical button presses and continuously monitor LED states. This created a closed-loop feedback system that ensured software automation only proceeded when the gateway was physically ready.

Tools & Agents Used
  • TestJig Agent – for physical button actuation and LED validation
  • Mobile App Agent – for BLE discovery, pairing, and mobile app workflow automation

Results

  • Achieved 100% reliable 30-second hardware trigger execution
  • Eliminated human timing and coordination errors
  • Provided unified Excel test reports covering hardware, BLE, and mobile validation
  • Converted a fragile manual process into a single-click automated regression suite

Impact

By combining precise hardware control with deterministic mobile and BLE automation, TestBot delivered perfect synchronization between physical gateway behavior and mobile workflows. The customer gained a scalable, repeatable validation framework ready for both regression testing and production-level certification.

Conclusion

Using TestBot’s TestJig Agent and Mobile App Agent, the Fire Panel Gateway’s BLE provisioning was transformed from a high-risk manual procedure into a fully automated, enterprise-grade validation pipeline — ensuring reliability, traceability, and speed across every firmware and mobile app release.
