Why fret if you lose the physical door key when you have a digital key? An Apple HomeKit®- and Amazon Sidewalk-compatible smart lock that can be retrofitted onto almost any existing door has been launched by California-based company Level Home. The Bluetooth® Low Energy (Bluetooth LE) ‘Level Lock’ is powered by Nordic’s nRF52840 Bluetooth 5.2/Bluetooth LE advanced multiprotocol System-on-Chip (SoC) and enables instant and secure keyless entry to authorized users.
The nRF Connect SDK [Software Development Kit] is recommended for nRF52840 software development. The nRF Connect SDK integrates the Zephyr RTOS, supports applications using Bluetooth LE, Bluetooth mesh and Thread, and includes examples, Bluetooth LE profiles and driver support for all peripherals. The SDK also includes a migration of Nordic’s Bluetooth SoftDevice Controller from the company’s proven SoftDevices used with the nRF52 Series. The nRF5 SDK can also be used for development with Nordic’s S113, S132 and S140 SoftDevices Nordic’s Bluetooth RF protocol stacks.
“The nRF52840 is a super versatile SoC that checked all the boxes for us and provided multiprotocol support,” says Ken Goto, co-founder and CTO of Level. “We were highly constrained in terms of physical space and power consumption, so the SoC footprint for its performance capabilities and available GPIOs was a great match. It had more than enough CPU performance to support our encryption needs, enabled us to add new protocols without changing the hardware platform, and helped introduce an entirely new smart home entry design and experience.”
