NRF51822 Datasheet, PDF (2/2 Pages) List of Unclassifed Manufacturers – Multi-protocol Bluetooth Low Energy and 2.4GHz proprietary system-on-chip

Easy, fast and safe code development
The nRF51822 offers developers a clean separation between
application code development and embedded protocol stacks.
This means compile, link and run-time dependencies with the
embedded stack and associated de-bugging challenges are
removed. The Bluetooth low energy stack is a pre-compiled binary
available from Nordic Semiconductor, leaving application code
to be compiled stand-alone. The embedded stack interface uses
an asynchronous and event-driven model removing the need for
RTOS frameworks. Developers can concentrate with confidence
on what they do best - developing applications.
Maximum re-use and easy migration
The devices in the nRF51 series are pin compatible enabling
migration between technologies such as Bluetooth low energy
and ANT with no layout changes. The common HW architecture
ensures that one codebase can be re-used effortlessly between
nRF51 series devices. Variants in the nRF51 series enable simple
choices tailoring device selection to desired wireless protocol and
feature requirements with little or no changes.

S110 protocol stack
The nRF51822 is complemented by
the S110 Software stack. The S110
is a complete Bluetooth low energy
stack supporting the peripheral
and broadcaster GAP roles. It offers
GATT/GAP andL2CAP APIs to the
application. The S110 protocol stack
can be downloaded along with adopted
Bluetooth low energy profiles from
Nordic Semiconductor.
