“The long battery live enabled inpart by the Nordic SoC’s low power consumption avoids the need to frequently charge the device with USB and is a significant lifestyle benefit to our target customers,” says Ki Kwang Sung, Chief Technology Officer with D.O.T.
Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines a 64MHz, 32-bit ARM® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. When launched, the SoC was the world’s highest performance single-chip Bluetooth LE solution.
The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 4.2 qualified RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice supports Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.
“Having searched across the globe to find the best Bluetooth LE fit for our flagship product, we decided to utilize the nRF52832 SoC based on the key components that optimize the user experience of the Dot Watch―energy consumption, price point, and size,” says Ki Kwang Sung.
“Nordic’s Software Development Kit (SDK) and SoftDevice have proved uniquely and immensely helpful in the ongoing development and improvement of our Braille smart watch.”
D.O.T is finalizing preparation for a global launch of the Dot Watch through its website.
