General Information
Bug Fixes:
• Using a short connection interval and exercising high throughput, there was some loss of packets. This
was fixed by adding host to application flow control support.
• Bonding was unstable at short connection intervals. This is now fixed.
• Fixed USB CDC Drivers to work with Windows 8.
• OAD sample project would fail if long connection interval was used. This was fixed by not allowing
parameter updates to the central device.
• Fixed linking errors in UBL project.
• Fixed minor issues in sample apps to work with PTS dongle.
• Fixed USB descriptors in HostTestRelease to display correct string.
Known Issues:
• Use of the NV memory (to save application data or Bluetooth Low Energy Host bonding information)
during a Bluetooth Low Energy connection may cause an unexpected disconnect. The likelihood of this
happening increases with frequent usage, especially when using short connection intervals. The cause
is related to the NV wear algorithm which at some point may cause an NV page erase which can
disrupt system real-time processing. It is therefore recommended that the NV memory be used
sparingly, or only when a connection is not active.
• HCI packet size of 128 bytes or more will be disregarded by the stack, and as such, no HCI event will
be returned.

Glucose were fully tested and passed certification. Other profiles with no code changes since 1.3.1
were sanity tested only.
Changes and Enhancements:
• Added Running Speed and Cadence profile and service. An example application demonstrating
running speed and cadence is provided.
• Added Cycling Speed and Cadence profile and service. An example application demonstrating cycling
speed and cadence is provided.
• Added delay before performing Connection Parameter changes. Implemented conn_pause_peripheral)
and TGAP(conn_pause_central) timers as described in CSA 3 rev 2, Gap Connection Parameters
Changes, Section 1.12. Updated HIDAdvRemote, HIDEmuKbd, KeyFob, SensorTag, and
SimpleBLEPeripheral applications.
• Update Privacy Flag and Reconnection Address characteristics permissions (Erratum 4202)
• A new Windows USB CDC driver has been included in the installer. This new driver is signed and is
functional on Windows 8 systems.
