Vinayak Kariappa Chettimada d382fca6ff Bluetooth: Controller: Fix HCI command buffer allocation failure Fix HCI command buffer allocation failure, that can cause loss of Host Number of Completed Packets command. Fail by rejecting the HCI Host Buffer Size command if the required number of HCI command buffers are not allocated in the Controller implementation. When Controller to Host data flow control is supported in the Controller only build, ensure that BT_BUF_CMD_TX_COUNT is greater than or equal to (BT_BUF_RX_COUNT + Ncmd), where Ncmd is supported maximum Num_HCI_Command_Packets in the Controller implementation. Relates to commit `81614307e9` ("Bluetooth: Add workaround for no command buffer available")'. Relates to commit `297f4f481f` ("Bluetooth: Split HCI command & event buffers to two pools").

.. zephyr:code-sample:: ble_peripheral_hr
   :name: Heart-rate Monitor (Peripheral)
   :relevant-api: bt_hrs bt_bas bluetooth

   Expose a Heart Rate (HR) GATT Service generating dummy heart-rate values.

Overview
********

Similar to the :zephyr:code-sample:`ble_peripheral` sample, except that this
application specifically exposes the HR (Heart Rate) GATT Service. Once a device
connects it will generate dummy heart-rate values.


Requirements
************

* BlueZ running on the host, or
* A board with Bluetooth LE support

Building and Running
********************

This sample can be found under :zephyr_file:`samples/bluetooth/peripheral_hr` in the
Zephyr tree.

See :zephyr:code-sample-category:`bluetooth` samples for details.
