Jennic has released a low-cost starter kit that allows developers with little or no wireless experience to develop products. The JN5139-EK020 IEEE802.15.4/JenNe simplifies the evaluation and application development of low-power wireless connectivity products using the company’s JenNet networking stack.

The kit: simplifies wireless network development with the JenNet networking protocol stack, based on the IEEE802.15.4 standard; supports Jennic JN5139 32-bit wireless microcontroller ICs and modules; demonstrates single-chip wireless microcontroller and coprocessor configurations; eliminates the need for additional development tools.

It also provides the flexibility to develop wireless capability by using Jennic JN5139 microcontrollers and modules as wireless processors or coprocessors. In the wireless coprocessor configuration, the kit demonstrates nodes adding wireless connectivity to a PC or embedded processor via a serial port and Jennic’s AT-Jenie serial communications API.

In the single-chip configuration, the kit demonstrates the protocol and application both running on the JN5139 32-bit wireless microcontroller. The Jenie ‘C’-based API provides communication between the application and the wireless connectivity protocol.

The kit consists of three nodes, preprogrammed with a range of example applications to demonstrate the capabilities of wireless sensor networks.

Each node includes a standard Jennic module that integrates a JN5139 wireless microcontroller and an antenna. Operating in the ISM band at 2.4 GHz, the modules have worldwide RF approval.

The JenNet stack provides a higher-layer networking solution based on the IEEE802.15.4 standard. It implements networks ranging from simple point-to-point systems, to large tree or linear networks of devices.

The Jenie and AT-Jenie programmer interfaces simplify access to the commands for building and running the network, de-skilling the task of designing the network and allowing the developer to concentrate on designing their application.
