The Weightless SIG has launched a complete Weightless-N development environment for low power wide area network connectivity in Internet of Things (IoT) projects.
The development kits include a desktop base station with the same functionality as a commercial grade base station packaged in a non-ruggedised casing, a base station antenna, an end product module mounted on a development carrier board with external connections, a module antenna and a complete set of cabling.
The SDK incorporates an ARM Cortex-M3 MCU with 128KB of flash memory. The kit also includes supporting software tools, Simplicity Studio and a GNU C Compiler (GCC), together with a complete user guide.
Weightless CEO, William Webb, commented: “Designers have been keenly anticipating the launch of the Weightless SDK - that wait is now over.” He added: “We’re keen to see LPWAN projects commence rapidly so to celebrate the launch we’re making it easy to engage with Weightless technology by offering a limited number of kits available for free.”
Nwave Technologies is making the development kit available at cost and the Weightless SIG is paying this cost making SDKs free to developers. A refund of the membership fee is also being offered by the Weightless SIG to Associate Members that submit product for certification.
Yury Birchenko, CEO of Nwave Technologies, commented: “We’re very excited to offer developers the opportunity to start designing their next IoT product immediately; working with the Weightless SIG to make the SDK free of charge is completely aligned with that goal.”
He continued: “We are engaging right now with a significant, diverse and global community of developers who have eagerly awaited the launch of a Weightless development environment.”
Weightless SIG Members get access to all of the open standard specifications, the test specifications, the test and certification programme and the right to sell product using the technology on a royalty free basis.
The Weightless Special Interest Group is a global, democratic, non-profit, member based organisation devoted to developing the open standard IoT connectivity technology. Three versions of Weightless exist or are in development.
Weightless-W is a high performance, two-way communications solution designed for use in TV White Space bands.
Weightless-N uses a star network architecture and operates in sub-GHz spectrum using ultra narrow band (UNB) technology. It is designed around a differential binary phase shift keying (DBPSK) digital modulation scheme to transmit within narrow frequency bands using a frequency hopping algorithm for interference mitigation.
Weightless-P, which is in development with Taiwanese company M2COMM is an ultra high performance LPWAN connectivity technology, which will use a narrow band modulation scheme offering a bidirectional communications capability to enable a high quality of service (QoS) and add on functionality.
