Devices drop offline and never reconnect. Telemetry disappears between the sensor and the dashboard. Hardware and firmware pass separate tests but fail together. Hughie Systems traces these failures across the product, implements corrections, and verifies recovery under real operating conditions.
Integration problems live between ownership boundaries. Firmware may follow one model of device state while the backend follows another. Hardware timing may violate an assumption in a driver. A nominal test may pass while recovery behavior fails under power loss, packet delay, or partial configuration.
“Every subsystem passes, but integration is blocking the launch.”
Drivers, firmware, and backend services pass their own tests, but startup sequencing, interface timing, or conflicting device state breaks the complete product. We trace the failing interaction across team boundaries.
“The device drops offline and never reconnects.”
Cellular or Wi-Fi recovers, but the MQTT session stays disconnected until someone reboots the device. We investigate modem, network, TLS, and application state, then exercise reconnect and resubscribe behavior.
“Manufacturing adds a new set of failures.”
Programming, identity, calibration, configuration, validation, traceability, and test results are not yet a dependable repeatable flow.
“Customers report missing data, but our logs show nothing.”
Telemetry may be lost, duplicated, delayed, or dropped when queues fill. We trace data from acquisition through buffering and transport to backend receipt, adding timestamps and counters where visibility is missing.
Hughie Systems can own the investigation, define the system-level contract, implement the highest-value fixes, and build enough observability and validation to prove behavior beyond the original failure case.
Make timing, data ownership, initialization, command handling, error behavior, and recovery explicit across firmware, hardware, communications, and backend boundaries.
Investigate connection drops, failed MQTT reconnects, retry loops, and stalled transfers. Implement explicit connection state, resubscription, bounded retries, buffering, and recovery for intermittent cellular, Wi-Fi, Ethernet, and mesh links.
Capture the minimum useful health, state, logs, counters, version data, and fault history required to diagnose the product remotely and shorten time to root cause.
Exercise startup, long-running behavior, degraded communications, power interruption, corrupted or missing state, production configuration, and recovery paths before deployment scale makes failures expensive.
The goal is not to produce a boundary diagram and stop. The investigation follows real signals, state transitions, timing, data, and control across the product until the failure is explained and a durable correction can be verified.
Tell us which components work separately, what fails when they run together, and what restores operation. Include the network type, available logs, and the milestone at risk.
