The nRF51 SDK documentation includes descriptions and other reference material to help you understand the various components of the SDK. Examples are provided for development purposes only and should always be tested with your design.
See Getting Started for instructions on how to run the provided examples.
This version of the SDK supports the following SoftDevices:

For other devices and boards, see the SDK documentation, section
"Using the SDK with other boards".
Changes:
- Flash access module has been refactored (pstorage).
ANT:
- Both the S310 and the S210 SoftDevices now support an extended
number of ANT channels (16).
Libraries:
- Heart Rate Monitor Profile
- ANT stack configuration
- ANT channel configuration
- ANT channel state indicator
- ANT pulse simulator
Examples:
- The ANT HRM examples have been refactored.
- The Bicycle Power examples (ant_bicycle_pwr) support S310.
ANT + BLE (S310):
The following examples were added:
- Bluetooth LE and ANT combined heart rate example (ble_ant_app_hrm).
- Experimental ANT Shared Channels (experimental_ant_shared_channel_master_to_master,
experimental_ant_shared_channel_slave).
BLE:
- Advertising module has a new mode: Low Duty Cycle Directed Advertising.
- Running Speed and Cadence Client added as experimental.
- Bluetooth Developer Studio template added as experimental.
- Heart Rate Sensor example (ble_app_hrs) supports S310.
- Running Speed and Cadence example (ble_app_rscs) supports S310.
- Combined Peripheral and Central example added as experimental.
- DFU Signing using Elliptic Curve Cryptography added as experimental
(using the same elliptic curve and hashing algorithm as Bluetooth
Low Energy 4.2 Secure Connections).
Fixed issues:
- Pstorage now supports updates of bond split across two pages.
- Advertising module can be set to infinite time-out.
- Corrected clock source in BLE multiactivity beacon example.
- Serialization HCI transport layer: Receiving packet-buffer is not
freed while sending ACK or NACK.
Known issues:
- Device Manager is not supported in multi-role S130 operation.
- Device Manager works in peripheral or central only operation on
S130. This must be decided at compile time.
- The DFU over BLE example has been tested to work with a minimum
connection interval of 11.25 ms. The application cannot handle
connection intervals lower than 11.25 ms and may undergo a system
reset in the middle of a firmware update.
Workaround: If you face unexpected disconnects during the firmware
update process, consider increasing the connection interval used
by the master.
- App_pwm occasionally gives inverted signal.
- The old manual procedure for testing buttonless DFU, as specified in
the documentation, can lead to the DFU process hanging or returning
an error when used with Master Control Panel 3.8 and newer.
