IOWA Features

Quickly Create a Powerful Smart Device

IOWA fast-tracks the "smart" part of IoT devices thanks to its optimized code. But more than simply creating an IoT device, IOWA provides several security options for critical and sensitive devices, and was designed for situations where every line of code counts. Tight on space and don't need all the features below? You can remove them easily through feature flags.

Core Capabilities


LwM2M 1.0, 1.1 & 1.2 support

All versions of LwM2M are available in IOWA; all are backwards-compatible


Flexible hardware and software abstraction layer

IOWA is platform-agnostic, allowing you to implement it on any MCU, OS, or security implementation


Network and transport agnostic

IOWA can operate on any network and transport protocol, even the most constrained


Thorough object management

Take advantage of the LwM2M and IPSO Objects already implemented in IOWA or integrate your own, either standard or custom 


Custom object code generation

Use IOWA's XML script to generate the necessary code to add any custom Object to your device application


Comprehensive logging mechanism

Use the IOWA logs to quickly identify  roadblocks and accelerate development


Device management server building blocks

Build your own Device Management Server based on IOWA SDK



End-to-end security encryption


Ensure end-to-end security from a device to the device management server with OSCORE. Add another layer of encryption when using TLS/DTLS


Easy interaction with a secure element


Port your code on any security implementation in use, whether software or hardware based, including hard or virtual Secure Elements

Client – Server Interaction


Efficient data collection

IOWA enables you to collect any data gathered by a device's sensors through pull and push mechanisms


Thorough registration rules configuration

Configure servers to communicate with the device, whether Bootstrap or Production, and define their ACLs and fallback rules


Advanced firmware update

Manage firmware updates using push or pull methodologies on CoAP(s) or HTTP(s)

Communication Optimization


Wide encoding support

Optimize your data footprint through a wide range of payload encoding formats including, CBOR, SenML JSON, SenML CBOR, LwM2M CBOR, TLV, etc.


Optimized management of intermittent connectivity

IOWA enables fine tuning of CoAP congestion control rules and LwM2M registration lifetime to maximize efficiency and data transmission

Built-in CoAP block-mode support

Ensure that your data is sent, independent of the payload size and network protocol


Efficient notification storage

Ensure no data is lost, even when there is inconsistent network quality


Session resumption and Connection ID support

Accelerate re-authentication procedures to reduce data and power-heavy exchanges


Direct CoAP interface

Rely on IOWA’s CoAP stack to create a dedicated channel to communicate with your application data

Coming Soon

Processing Optimization


Footprint optimizer

Use IOWA feature flags to ensure your implementation is as lean as possible to avoid affecting your hardware's performance


Streamable resources support

Ensure your largest data are successfully transmitted without burdening your devices’ memory


Asynchronous response support

Configure IOWA so that it works with asynchronous responses to avoid slowing down your operations


Resilient context storage

Ensure operations always go through without restarting all transmissions, even on devices that are mostly dormant
