Group of variables used for monitoring and; optionally, for data logging.

  • You can add variables by dragging and dropping symbols in IoTize Studio (configuration software)
  • You can link profiles to bundles to manage access rights
  • You can define the related data logging settings (enabled or not, frequency)

CORTEX M: MCU technology

  • If your target system is based on CORTEX M MCU, you can use the SWD protocol for the connection with TapNLink
  • In this case, you don't need to modify your target application to use TapNLink
  • You can also update or even debug your target application with TapNLink

Data logging

Object to cloud data transfer, implying the following operations

  • Tap data acquisition: the variables values are retrieved from your target application (though SWD or S3P)
  • Tap data storage (in an external EEPROM) e.g. sensor demo application can store about 700 data packets
  • 'Tap to smartphon'e transfer (when a smartphone is used as a WAN gateway)
  • Cloud transfer: done by a smartphone (or directly by a Tap)
  • Message translation:
  • done in cloud gateway (or directly in IOT platform)
  • translates the IoTize specific format to standard JSON format used by the IOT platforms
  • Cloud storage: in the cloud IoT Platform
  • Data visualization: in the cloud IoT platform (IoTize Primer Cloud Platform for the Primer)


  • In IoTize context, applies to TapNLink firmware or target application firmware
  • Both are related to firmware update capability
  • Generic definition is code of an embedded application.


Mobile device or PC connected to a Tap

Host protocols

  • Protocols used to connect a Tap to an 'external' system: mobile device, PC, (cloud) server
  • These protocols are detailed in the section UserManuals/Host Protocols
  • Most of these protocols are wireless (NFC, BLE, WiFi, Lora) with the exception of UART (mainly used in production, for 'mass configuration')


Identity and external management.


IoTize Communication Service.

  • Obsolete, replaced by IoTize Tap Manager after July 2018.

Mobile device

Android, iOS or Windows mobile appliance (smartphone, tablet or Windows 10 PC)



  • The TapNLink product range is mostly designed for MCU based target applications (as opposed to the TapNPass products, which connect to target system though an industrial bus and support physical connections such as RS-232, RS-485, Ethernet, CAN...)


  • R/W access in (pseudo) real-time to target application variables, from a "smartphone", through a Tap.
  • The monitoring application can be developed in 3 different ways:

  • from HTML/JavaScript pages which can be automatically generated from IoTize Studio '(these pages can further be customized)

  • from a generic application
  • from native application, using API provided by IoTize
**Monitoring from remote location**: - Monitoring is done from a Web application (which can be run from a PC, smartphone, tablet) through a network. -->

MQTT broker

  • 'Relay MQTT broker': connects IoTize Studio to the Tap (through a smartphone) at the design stage

  • 'Cloud MQTT broker': connects the Tap to the IOT platform (through a smartphone). Also referred as the 'cloud_IOT_platform' gateway

  • For the Primer:

  • these brokers are hosted and managed by IoTize

  • they are implemented on a unique Mosquito server

  • On the standard version, the  implementation can be customized (and can be different for the 2 brokers)


  • Short for "Personal Computer/Smart Card": specification for smart-card integration into computing environments
  • Used as the connection mode between IoTize Studio and your Tap

Primer Kit

Similar to "TapNLink Primer". Refers specifically to all the physical "components" included in the kit (the Tap, the cable, the demo board, the blister...).

S3P (Serial Software Secure Protocol)

Proprietary target protocol to connect the target application and the Tap (alternative of SWD)

Sensor Demo application
