Nut finder uses Nordic SoC for Bluetooth low energy positioning via Apple Find My app

Nutale Air Tag-F11X anti-lost device uses nRF52832 SoC to help users locate valuables and become part of Apple's Find My network

Oslo, Norway – June 28, 2022 – Chinese technology brand Nut has successfully developed a new lightweight finder and anti-lost device “Nutale Air Tag-F11X” to help users find lost valuables. This product is designed to work with the Apple Find My™ network consisting of hundreds of millions of Apple devices around the world . Users attach the Nutale Air Tag-F11X that supports the Find My function to personal items such as keys, backpacks, wallets or purses, and add it to the Apple Find My application on iPhone or iPad, and then they can locate lost or misplaced items through the private and secure Apple Find My network.

The Nordic nRF52832 SoC integrated in this anti-lost device supports Bluetooth 5.3 specifications and has a maximum transmit power of 4 dBm, which can meet the requirements of the Apple Find My network. Even if the item is far away from the iPhone or iPad and beyond the effective transmission range of low-power Bluetooth, the Nutale Air Tag-F11X can still be located through the "Find My Network". If the item is small and difficult to find, the user can issue a command in the "Find My" application to trigger a loud (110 dB) ringtone.

The nRF52832 SoC's 64 MHz, 32-bit Arm® Cortex® M4 processor with floating point unit (FPU) is used to perform the core processing tasks of the Nutale Air Tag-F11X, enabling the anti-lost device's built-in motion sensor to monitor the status of items in near real time. Nordic's software development kit (SDK) is compatible with the Apple Find My network, allowing developers to easily design low-power Bluetooth devices that support the Find My network and maximize battery performance. The Nutale Air Tag-F11X is equipped with a CR2032 button battery with a service life of more than one year.

Devices that support the Find My network emit a secure low-power Bluetooth signal so that nearby Apple devices on the network can detect the signal and report their approximate location to the owner. These devices send the hardware's location information to iCloud so that the device can be located on a map in the Find My app. The entire network process is end-to-end encrypted and anonymous, so no one else, not even Apple, Nut or Nordic Semiconductor, can see the location of the item, or the location or identity of any device that helped locate it.

“The nRF52832 SoC has excellent processing power and large memory capacity to achieve the privacy and security of the Find My network,” said Bing Han, CTO of Nut. “Nordic’s excellent support in providing high-quality SoCs, comprehensive SDKs, and other development tools helped us design a stable and reliable item finding solution.”

Han added: “ Using a mobile device such as a smartphone to locate a Bluetooth low energy product can significantly reduce power consumption compared to GPS positioning products , thus saving energy and cost.”

“Find My technology has established a community of item-finding apps, and we are pleased to see Nut using Nordic’s Bluetooth low energy products in its latest anti-lost device that supports the Apple Find My network,” said Wu Di, sales manager for Nordic Semiconductor in North China.

Wu Di continued: "Nut brings a lot of innovative ideas to item finding, and with the support of Find My technology, the company will provide more options to improve the user experience. Nordic has invested a lot of resources in maintaining the wireless connectivity ecosystem. Our cooperation with Nut on the Find My solution is a testament to our strong capabilities covering a variety of wireless protocols."
