Baccara

The BACCARA GEM-SMART+™ app is an Android mobile product for configuring, controlling, and monitoring compatible smart solenoid valves. moblers delivered the Flutter application and its hardware integration in eight months.

An important correction to the previous case-study copy: BACCARA’s official GEM-SMART+ product flyer specifies NFC communication, not Bluetooth, and identifies the app as Android-only.

Confirmed product capabilities

• Configure DC or Latch solenoid types.
• Set PWM duty cycles, timers, and feedback parameters.
• Control and monitor compatible GEM-SMART+™ solenoid valves.
• Exchange data locally between an NFC-capable Android device and the hardware.
• Support both end users and qualified technicians through a mobile interface.

Availability and deployment

The GEM-SMART+™ app is available on Google Play under package com.moblers.bacara. BACCARA’s official flyer describes the product as Android-only; no iOS release is confirmed.

Facts published on the Google Play listing:

• Publisher: Baccara, in the Tools category.
• Current version: 1.3, last updated 8 September 2024.
• Description confirms configuration and operation of the GEM-SMART+™ DIN 43650 connector over NFC.

Confirmed prerequisites are an NFC-capable Android phone and compatible GEM-SMART+™ hardware. Users obtain the app from Google Play and follow its device setup flow while near the solenoid connector.

Device and OS compatibility

The Google Play listing does not publish a minimum Android OS version, supported phone models, or NFC chipset guidance. Third-party APK trackers such as AppBrain report an Android 5.0+ requirement; that figure is not confirmed by BACCARA or moblers and should not be used for procurement.

Also not published: minimum GEM-SMART+™ firmware version, the exact commissioning checklist, the Android NFC permission prompts users will see, practical NFC range guidance, account or licensing requirements, MDM or private APK distribution, on-site rollout services, and firmware or app update procedures. Nothing on this page should be read as confirming that any of these options exist.

Technical implementation

Client application. Flutter is the confirmed application framework. Flutter SDK version, state-management approach, package names, local-storage implementation, native libraries, automated-test frameworks, and release tooling are not publicly disclosed.

Hardware communication. BACCARA documents NFC communication between the Android app and the GEM-SMART+™ connector. NFC specification, discovery and authentication flow, payload format, command schema, telemetry schema, firmware update support, retry behavior, and maximum devices per session are not publicly disclosed.

Delivery systems. CI/CD, build signing, test automation, monitoring, release approvals, and any backend hosting are not publicly disclosed.

NFC technical reference

There is no public protocol specification or developer guide for the GEM-SMART+™ NFC interface. The product flyer is the only authoritative public document, and it describes the interaction at product level rather than protocol level.

The following are therefore unavailable to integrators from public sources: the NFC protocol stack (NDEF, ISO-DEP, LLCP, or custom), frame and payload encoding, payload versioning, command identifiers and parameter formats, telemetry field names and units, sampling cadence, maximum payload size, fragmentation rules, CRC or integrity checks, session discovery and teardown sequence, acknowledgement and timeout behavior, retry and backoff rules, concurrent-device limits, and whether firmware can be updated over NFC.

Integrators who need to implement or test against this interface should request the specification directly from BACCARA. moblers will not publish protocol-level detail for a client’s hardware interface without written approval.

Backend architecture: local-only as documented

Every capability confirmed in public sources — configuration, control, monitoring, and parameter changes — operates locally between the NFC-capable Android phone and the solenoid connector. No cloud backend, REST or GraphQL API, WebSocket or MQTT endpoint, remote command relay, identity or SSO service, telemetry database, push-notification service, analytics or crash-reporting SDK, developer API, or remote commissioning path outside NFC range appears in any public source.

Integrators planning around this page should assume local, offline operation and no remote control beyond NFC proximity. This statement reflects the boundary of published evidence rather than a warranty that no such components exist internally; BACCARA is the only party that can confirm the presence or absence of remote services and any associated rate limits or availability commitments.

Security specifics

NFC is a short-range communication channel; proximity alone should not be presented as proof of encryption or authenticated device identity.

The published material does not identify encryption algorithms or key lengths, pairing or authentication mechanisms, device identity or attestation checks, secure storage in Android Keystore, signed firmware and its verification method, command integrity controls such as MACs or signatures, replay protection through nonces or timestamps, technician-versus-user authorization roles, audit logging, penetration testing, code-audit dates, or compliance certifications.

For risk assessment, treat each of those controls as unverified rather than confirmed absent: the absence of public documentation is not evidence that a control is missing, and it is equally not evidence that one is present. Organizations performing a security review should request written confirmation from BACCARA for each control before relying on it.

Target industries and users

BACCARA’s flyer positions GEM-SMART+™ for machines and industrial applications. It explicitly describes use by users and qualified technicians who configure, control, monitor, and adjust compatible solenoid valves.

The confirmed use cases are:

• Rapid setup and selection of DC or Latch solenoid behavior.
• Precision tuning of PWM, timers, and feedback settings.
• Local control and monitoring at the equipment.
• Technician adjustment through an NFC-capable Android phone.

Agriculture, landscaping, municipalities, OEM partners, system integrators, and other segments may be plausible, but the available source does not confirm them as deployed customer cohorts.

Results and measurable outcomes

Confirmed result: moblers delivered the Flutter Android app in eight months with the configuration, control, monitoring, and NFC integration described above.

Not publicly disclosed: installation count, active users or devices, deployment dates, water or energy savings, setup-time reduction, connection success rate, telemetry latency, uptime, MTBF/MTTR, support-ticket changes, customer ROI, and attributable testimonials. No representative number should be published without a cohort, measurement window, method, and BACCARA approval.

Support, maintenance, and versioning

There is no public SLA for this product, and none should be inferred from moblers’ other service pages. Support scope, entitlements, and commercial terms are agreed per customer rather than published as a standard policy.

Specifically undefined in public materials: support contact channels and business hours, severity levels with initial-response and resolution targets, security-patch and feature-release cadence, whether updates can be made mandatory, the version-numbering or semantic-versioning policy, maintenance windows and planned-downtime notification, the split of responsibility between BACCARA firmware and moblers app updates, and support pricing tiers.

The Google Play listing does show release history in practice — version 1.3 was published on 8 September 2024 — but a single observed release does not establish a committed cadence. Customers needing defined response times, versioning guarantees, or a firmware-update process should confirm them in their BACCARA or moblers agreement.

Evidence boundary

This page distinguishes confirmed product behavior from implementation details that have not been approved for publication. Named backend services, APIs, NFC security mechanisms, cloud providers, distribution methods beyond Google Play, performance figures, and SLAs should not be inferred from example technologies or general moblers capabilities.
