Kiwink® for Maintenance

By flashing, the LED can send an error code and the failure can be identified straight away in the diagnostic process. For some applications, the user could even diagnose himself the breakdown and help the customer service team bring the right replacement parts on site.
Direct web-access to repair instructions with the smartphone

  • Reporting breakdown machine (Can help detect a persistent failure on a product at an earlier stage thanks to data recording)
  • Tools monitoring
  • Improved diagnosis
  • Optimization of the maintenance operations and procurement
  • Direct access web to repair instructions with the smartphone
  • Improved customer service

How does it works ?

Kiwink® is a registered trademark.

The smartphone sends a lighting message to the product by making the flash blink.

The smartphone sends a lighting message to the product by making the flash blink.The product LED receives the lighting message and processes it.

As an answer, the product LED sends a message by blinking without the eye noticing it.

The smartphone camera receives this message and the mobile application processes it. The data can be sent to the cloud if needed.

Technical Key Points & Performances

Downlink (20 cm max)

~ 1.5 kb/s  at 5 cm
~ 500 b/s at 20 cm
~ Protocol Data Unit : 10-20 bits

Uplink (50 cm max)

~ 10 to 50 b/s depending on the smartphone and flashlight model
~ PDU : unconstrained

Hardware

  • Throughput may vary across smartphones models (/10 for the flash)
  • Compatible with recent smartphones only: Android (>6.0), iPhone 5C,…
  • Front and rear camera are supported (n.b. reduced performances using the front camera)

Firmware size overhead

< 2 kB of flash, without optimizations

Microcontroller:  8, 16 and 32 bits

LED characteristics

  • Functional with any colors
  • LED viewing angle limits directivity (e.g. 15° -> 120°)
  • Works LED to LED
