Texas Instruments, Inc.
CC2540/41 Bluetooth low energy Software Development KitRelease Notes
BLE-Stack(tm) Version 1.4.1May 21, 2015
Notices:
– This version of the Texas Instruments BLE-Stack and software is a maintenance update to the v1.4.0 release. It contains several bug fixes and enhancements.
– The BLE protocol stack, including both the controller and host, was completely retested for v1.4.1.
– All Sample Applications in the SDK ported and verified for v1.4.1
– Default SDK installation path is C:\Texas Instruments\BLE-CC254x-1.4.1.xxxxx\ where "xxxxx' is the SDK build revision number.
– For guidance on how to port existing v1.4.0 projects to v1.4.1, refer to the "Additional Resources" section below.
Changes and minor enhancements:
– All projects have been migrated from IAR v8.20.2 to IAR 9.10.3. In order to build all projects, be sure to upgrade to IAR v9.10.3. – Smarter handling of connection parameter updates with multiple connections
– GAPRole_SetParameter(GAPROLE_ADVERT_DATA) changes the advertising data
– Allows removal of Service Changed Characteristic
– HAL components set to TRUE if not defined
– Added HCI Vendor Specific Guide revision history
– Several bug fixes. Bug Fixes:
– Fix for RSSI value does not change in V1.4 stack
– Fix for Number HCI Commands parameter not updated in Command Complete Event
– Fixed CC254x UART DMA reception discontinuity
– Fix for SPI reliability improvement
– Fix for updating advertisement data while simultaneously connected as peripheral and advertising
– Fix for filtering duplicate ADV reports even when the filter is FALSE
– Fix for possible race condition T2ISR vs T2E1 on slow wakeups
– Fix for HAL_DMA_CLEAR_IRQ() can be interrupted causing missed ISR cause
– Fixed HCI_LERemoveDeviceFromWhiteList Fails after Scan
– Watchdog Kick Macro Affected by Interrupts
– Fixed HCI_EXT_ResetSystem soft reset to work as expected on CC254x
– Fixed White List Irregularities During Scan / Connect
– Fixed Overlap processing that causes Slave task to last too long for next event setup
– Add BTool Support for new field 'encKeySize' added to GATT_AddService command
– Fixed CC254x UART DMA reception discontinuity
– Fixed CC254x unresponsive when resetting in initiating state
– Fix for after successful reconnect using private non-resolvable address, rebond fails with "Key Req Rejected"
– Fix for CC254x host Bond Manager setParam configuration does not support M/S LinkKey enc exchange
– Fixed TICKSPD, CLKSPD is overwritten on X/HS-OSC change
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.
