Yantrr Connection Manager

Automated device management is a key component of any at-scale IoT deployment. Yantrr Connection Manager exposes easy to use APIs to transparently manage device connectivity with high degree of reliability, and is fully compatible with the Yantrr Device Cloud.

We have developed connection profiles which are easy-to-understand and are widely used in M2M/IoT deployments:

  • Intermittent: Period or event-based data exchange between sensor and cloud.
  • On Demand: Request-based data exchange.
  • Persistent: Always ON, like streaming service.
  • SOS: Critical/Panic state information exchange in case of emergency

Following table gives an highlight of different connection profiles, and modem features needed in different IoT industry verticals

YCM Features

Yantrr connectivity manager is a generic connectivity framework which has abstraction layer to hide complex states of modem and exposes API for user to set easy modes for connectivity management.

Transparent connection

Implements pre-defined connection profiles, transparent background handling of connection, no manual reconnection requires in case of failure.

Open APIs

Simplifies the complexity of using AT or QMI command, transparent network handling using easy to use API, supports SIM application toolkit, FW upgrade, FOTA.


The architecture is fully responsive, based on asynchronous callbacks, supports registration of user-defined functions as callbacks.
