The fresh releases include mbed Device Connecter, a service at no charge letting businesses connect and securely manage IoT devices.
Last year ARM introduced its mbed IoT device platform and it has improved its mbed operating system and introduced mbed reference designs.
Kriztian Flautner, general manager of IoT business at ARM said that his company has produced tools from a single cloud connected sensor to a set of more intricate devices for enterprise grade deployments of IoT.
The device connector, he said, lets developers connect devices in prototypes, build secure web applications and improve managing services.
The reference designs include a wrist based connected device with a battery life of eight weeks, and a smart city reference design with mesh network protocols.
