ESP32 BLE Companion App Development Fixed Price for Startups sits at the hardware–software boundary — where 3D-printed prototypes, BLE dev boards, and companion apps must ship together without a 12-month PCB program. Most agencies only do software; we build the app, cloud, and device integration while you iterate enclosure and firmware with mechanical partners.

Validate Physical + Digital Together

Print enclosure iteration 1–3 before locking app UX. Button placement, LED feedback, and grip shape change entire mobile flows.

FDM print: $50–$300 per iteration for form testing
Dev board (ESP32/nRF52) inside print for BLE demos
Companion app MVP: $4,500–$12,000 depending on BLE complexity
Defer injection molding until pre-orders or pilot POs

Software Scope for Connected Hardware

React Native companion app, device pairing/provisioning, telemetry to Supabase, OTA hooks, support admin via Retool v1.

BLE GATT integration via react-native-ble-plx
Device registration + firmware version tracking
Push alerts on sensor thresholds
Skip custom PCB firmware — integrate your team's spec

Certification Runs Parallel

FCC/CE/battery safety may lag software beta — launch TestFlight while cert proceeds; don't block user learning on FCC timeline.
