NOTE: This selection is marked EXPERIMENTAL. It is incomplete and, hence, untested. It still lacks any low-level Bluetooth drivers and is missing the network interface driver.
Squashed commit of the following:
wireless/bluetooth: Fixe last of compile issues. Now compiles without errors or warnings.
wireless/blutooth: Add macros BT_GETUINT16() and BT_PUTUINT16(). Fix more compile errors. Only one file now generates compile errors.
wireless/bluetooth: Add macros BT_LE162HOST() and BT_HOST2LE16().
wireless/bluetooth: Add bt_queue.c; begin fixing comple errors. Many more compile problems yet to resolve.
Kconfig edited online with Bitbucket
wireless/bluetooth: Struggling to remove nano_fifo logic: Replace buffer management with IOB allocate... this changes some logic and might have some side effects. Use messages queues instead of nano-fifos to inter-task communications. nano-fifos still used in 'frag' logic... whatever that is.
wireless/bluetooth: Fix numerous typos introduced by an ill conceived search-and-replace.
wireless/bluetooth: Add message queue support to manage interthread buffer transfers.
wireless/bluetooth: Replace fibers with kernel threads.
wireless/bluetooth: Fix a few initial compile errors. Just the tip of the iceberg.
wireless/bluetooth: Complete leveage of the bluetooth stack including public header files.
wireless/bluetooth: Complete leverage of all Bluetooth source files. Still missing header files that defines the driver interface. Also missing the network driver implementation.
wireless/bluetooth: Fix some naming of static global variables.
wireless/bluetooth: Adds three more files ported from the Intel/Zephyr arduino101_firmware_source-v1.tar package (plus two original files).
wireless/bluetooth: Adds five more files ported from the Intel/Zephyr arduino101_firmware_source-v1.tar package.
wireless/bluetooth: Adds three more files ported from the Intel/Zephyr arduino101_firmware_source-v1.tar package.
wireless/bluetooth: First few files ported from the Intel/Zephyr arduino101_firmware_source-v1.tar package.
