TI BLE 协议栈代码

Texas Instruments, Inc. CC2540/41 Bluetooth Low Energy Software Development Kit Release Notes Version 1.3.2 June 13, 2013 Notices: - This version of the Texas Instruments BLE stack and software is a minor update to the v1.3.1 release. It contains some minor bug fixes and a few functional changes. - The BLE protocol stack, including both the controller and host, was completely retested for v1.3.2. The profiles Running Speed and Cadence, Cycling Speed and Cadence, and 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. Bug Fixes: - Some minor updates to glucose sensor and collector were made. - The gyroscope would draw continuous 6mA when enabled. The updated code now performs a read and turns off the gyro after 60ms. - The master�s host would accept invalid connection parameters requested by the Slave, and would send back the Connection Parameter Update Response with �parameters accepted�. The host now performs validation on these parameters. - When coming out of sleep, the HCI_EXT_ExtendRfRangeCmd would override HCI_EXT_SetRxGainCmd setting and set it to default gain. This has been fixed. Known Issues: - Use of the NV memory (to save application data or BLE Host bonding information) during a BLE 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. - The HAL SPI driver that was implemented since the v1.3 release can sometimes hang, particularly in cases in which power management is used and when there is heavy traffic on the SPI bus.

It contains some minor bug fixes, with no major functional changes. It also contains two additional projects for the CC2541 Advanced Remote Control Kit. - Since none of the profile source code was significantly changed since the v1.3 release, no additional re-testing of the profiles and sample application were done for v1.3.1. The only exception is the HID-over-GATT profile, which was fully re-tested for this release. The BLE protocol stack, including both the controller and host, was completely retested for v1.3.1. Major Changes and Enhancements: - The GAP parameter TGAP_LIM_ADV_TIMEOUT now uses units of seconds instead of milliseconds. - The HidAdvRemote Project has been added. This implements a full mouse-like pointing functionality using motion and gesture control. The project runs on the CC2541 BLE Advanced Control included as part of the CC2541DK-REMOTE kit. The application implements the HID-over-GATT (HOGP) profile with a report descriptor supporting the keyboard, mouse, and consumer control classes of HID devices. - The HidAdvRemoteDongle project has been added. This application runs on the CC2540USB dongle, and implements partial functionality of HID-over-GATT (HOGP) host with a fixed report descriptor to match that of the descriptor of the HidAdvRemote Project. This means that the HidAdvRemoteDongle was designed only to work with with the HidAdvRemote, and will not be compatible with any other HOGP devices. This project was created to allow users who are using a host device that does not have native Bluetooth Smart Ready support and/or does not have HOGP support to use the BLE Advanced Remote Control with their system. - For GAP central role applications, the bond manager now properly handles cases in which the peripheral device has erased previously stored bonding infomration. - A new HCI extension API has been added to allow peripheral/slave devices to temporarily ignore any nonzero slave latency value, and explicitly wake up at every connection event regardless of whether it has any data to send. The prototype for the API function HCI_EXT_SetSlaveLatencyOverrideCmd can be found in hci.h, including the description of the function. - A new HCI extension API has been added to allow the application layer to get or set a build revision number. Bug Fixes: - In some cases L2CAP Peripheral Connection Parameter Update requests failed due to a zero value in the transmitWindowOffset parameter when the connection was initially established. This has been fixed and updates should now work succesfully. - During bonding, connection failures would occasionally occur due to the OSAL Simple NV driver performing a page compaction and halting the CPU for longer than the time required for the link layer to maintain proper connection timing. To prevent this from occurring, the simple NV driver now has any API to force a page compaction if the page is full beyond a specified threshold. The bond manager calls this API everytime a connection is terminated to ensure that compaction occurs before the next connection is set up. - Occasional slave connection failures would previously occur in cases in which the master device sends Update Channel Map requests while a large slave latency value is in use. This has been fixed. - The SensorTag application now properly supports storage of GATT Client Characteristic Configuration Descriptor values with bonded devices. - After disabling advertising, the CC254x would unecessarily wake up for a short period of time 500ms later. This unecessary wake-up has been removed. - Upon Power-On Reset or after wake-up from PM3, a 400ms delay has been implemented, during which time the CC254x will not go into PM2 sleep. This allows time for the 32kHz crystal to stabilize. Previously, in rare cases with certain hardware configurations the CC254x could have timing issues due to the crystal not having time to stabilize. - Minor bug fixes to GlucoseSensor and GlucoseCollector projects. Known Issues: - Use of the NV memory (to save application data or BLE Host bonding information) during a BLE 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
