Spintly’s SMACC-UNO uses Nordic nRF52832 SoC for wireless connection between readers, smartphones and gateway

Oslo, Norway – April 24, 2022 – The access control technology company, Spintly, has launched what it claims to be the world’s first Bluetooth®-based access control reader.

The SMACC-UNO solution is designed to upgrade ordinary doors to intelligent doors. It eliminates the need to install cable controllers on site and allows seamless smartphone-based access to interior doors, barriers and turnstiles in commercial office space, shared workspaces, residential buildings and other facilities.


The SMACC-UNO readers, powered by Nordic nRF52832 SoC, scan credentials via the user’s smartphone or NFC card and allow access to the door after successful authentication without resorting to a central device or gateway. The reader and controller not only act as a wireless communication device with the user’s smartphone, but also as a node in a Bluetooth network for transmitting access and permission data to other readers and / or gateways.

Bluetooth network

The company also launched the ‘FI-B Gateway’ (also including the nRF52832 SoC), which communicates with all readers via the Bluetooth network and connects to the cloud using the MQTT protocol. All events such as access history and door events are transferred to the cloud through the gateway. Human and security administrators receive real-time notifications of facility movements via a smartphone app or web-based app.

Nordic’s nRF52832 SoC allows Bluetooth network connection between all readers and the gateway, as well as Bluetooth LE wireless communication with a smartphone. The SoC includes 2.4 GHz multi-protocol radio (supports Bluetooth 5.3, Bluetooth mesh, ANT, NFC and 2.4 GHz proprietary RF software) and a generous 256/512 KB flash memory and 32/64 KB RAM. nRF52832 supports Bluetooth mesh with nRF5 SDK (software development kit) for Mesh.

Generous memory capacity

“We chose the Nordic nRF52832 SoC for our SMACC-UNO solution because it supports the Bluetooth network protocol and provides generous memory capacity,” said Rohin Parkar, President and CEO of Spintly. “Nordic’s detailed reference projects helped us to design all of our products based on the nRF52832 SoC, while the Nordic DevZone Forum helped provide solutions to all the problems we encountered during the development process.”
