Bluetooth Smart stack removes smartphones from wearables

Smart wearable hub networks with wireless sensors do not need smartphones, declares Nordic Semiconductor, of its S130 SoftDevice, a concurrent multi-link central and peripheral Bluetooth Smart protocol stack for its nRF51 SoCs.

It is Bluetooth 4.1 compliant protocol stack and includes all Bluetooth Smart
protocol layers up to and including GATT/GAP. It supports multi-link central, peripheral, observer and broadcaster roles, GATT server and client, and event-driven, asynchronous and thread safe GATT/GAP and L2CAP APIs.

The S130’s ability to support concurrent multi-link central and peripheral roles makes
it suitable for Bluetooth Smart hubs that are not smartphones or tablets.
Features include an Over-The-Air Device Firmware Upgrade (OTA-DFU) capability
that leverages the nRF51 Flash architecture for in-the-field product firmware updates.

A SoftDevice is the company’s self-contained software stack for nRF51 Series SoCs that incorporates an RF protocol and application code. Employing an architecture that cleanly separates the Bluetooth Smart, ANT or 2.4GHZ proprietary SoftDevice
from the developer’s application code removes the need for the engineer to struggle with integration of their code as part of a vendor-imposed application development framework. This separation ensures the stack and application software operate independently, but communicate when necessary via event-driven APIs.

S130 alpha release is available now, with full production release scheduled for Q4 this year.
