Field service troubleshooting for technicians

Field service troubleshooting supports technicians with asset context, manuals, photos, diagnosis steps, parts checks, and escalation.

What this is for

This covers mobile troubleshooting flows for technicians who need asset context, issue pattern, manual snippets, and escalation on site.

  • The flow leads from asset to diagnosis questions and evidence, then to fix, escalation, or handoff.

  • appamass connects React Native/Expo for field work with TypeScript contracts, backend data, and Agent Development Kit (ADK)-based agents for research or diagnosis suggestions.

  • The first build should guide one common fault safely and show what can be solved on site and what needs escalation.

Asset context and diagnosis in the mobile flow

On site, clarity matters. The flow should show what is known, which check makes sense next, and when the case should be handed off.

What users see

Users see asset data, issue description, relevant manual sections, diagnostic questions, needed parts, and escalation path.

How it works

React Native/Expo, camera, offline cache, Firebase/FCM, asset records, retrieval, Agent Development Kit (ADK) agent steps, backend APIs, and push connect behind the flow.

What stays controlled

Offline data, asset history, spare-part status, escalations, photos, error codes, and service logs stay controlled.

A first troubleshooting flow

The first build should cover a common failure case and turn it into guided diagnosis.

Build asset lookup

Technicians find the right asset through scan, search, or location and see current context.

Guide diagnosis

Questions, manual sections, photos, and possible causes appear step by step.

Prepare escalation

When the case cannot be solved on site, diagnosis, media, and status go to the right team.
