+# Bluetooth Examples for NimBLE host
+
+Note: To use examples in this directory, you need to have Bluetooth enabled in configuration and NimBLE selected as the host stack.
+
+# Example Layout
+
+This directory includes examples to demonstrate BLE functionality using Apache MyNewt NimBLE (https://github.com/apache/mynewt-nimble) host stack.
+
+## bleprph
+
+Shows how ESP32 acts as a BLE Peripheral.
+
+See the [README.md](./bleprph/README.md) file in the example [bleprph](./bleprph/).
+
+## blecent
+
+Shows how ESP32 acts as a BLE central.
+
+See the [README.md](./blecent/README.md) file in the example [blecent](./blecent/).
+
+## blemesh
+
+Demonstrates BLE mesh functionality of NimBLE.
+
+See the [README.md](./blemesh/README.md) file in the example [blemesh](./blemesh/).
+
+## blehr
+
+Demonstrates standard Heart Rate measurement BLE peripheral.
+
+See the [README.md](./blehr/README.md) file in the example [blehr](./blehr/).

+# More
+
+See the [README.md](../../README.md) file in the upper level [examples](../../) directory for more information about examples.

+# BLE central example
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+This example creates GATT client and performs passive scan, it then connects to peripheral device if the device advertises connectability and the device advertises support for the Alert Notification service (0x1811) as primary service UUID.
+
+It performs three GATT operations against the specified peer:
+
+* Reads the ANS Supported New Alert Category characteristic.
+
+* After the read operation is completed, writes the ANS Alert Notification Control Point characteristic.
+
+* After the write operation is completed, subscribes to notifications for the ANS Unread Alert Status characteristic.
+
+If the peer does not support a required service, characteristic, or descriptor, then the peer lied when it claimed support for the alert notification service! When this happens, or if a GATT procedure fails, this function immediately terminates the connection.
+
+It uses ESP32's Bluetooth controller and NimBLE stack based BLE host.
+
+This example aims at understanding BLE service discovery, connection and characteristic operations.
+
+To test this demo, use any BLE GATT server app that advertises support for the Alert Notification service (0x1811) and includes it in the GATT database.
+
+A Python based utility `blecent_test.py` is also provided (which will run as a BLE GATT server) and can be used to test this example.   
+
+Note :
+
+* Make sure to run `python -m pip install --user -r $IDF_PATH/requirements.txt -r $IDF_PATH/tools/ble/requirements.txt` to install the dependency packages needed.
+* Currently this Python utility is only supported on Linux (BLE communication is via BLuez + DBus).
+
+## How to use example
+
+### Configure the project
+
+```
+idf.py menuconfig
+```
+
+### Build and Flash
+
+Build the project and flash it to the board, then run monitor tool to view serial output:
+
+```
+idf.py -p PORT flash monitor
+```
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
+

+# BLE Heart Rate Measurement example
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+This example creates GATT server demonstrating standard Heart Rate measurement service. It simulates Hear rate measurement and notifies to client when the notifications are enabled.
+
+It uses ESP32's Bluetooth controller and NimBLE stack based BLE host
+
+This example aims at understanding notification subscriptions and sending notifications.
+
+To test this demo, any BLE scanner app can be used.
+
+A Python based utility `blehr_test.py` is also provided (which will run as a BLE GATT Client) and can be used to test this example.   
+
+Note :
+
+* Make sure to run `python -m pip install --user -r $IDF_PATH/requirements.txt -r $IDF_PATH/tools/ble/requirements.txt` to install the dependency packages needed.
+* Currently this Python utility is only supported on Linux (BLE communication is via BLuez + DBus).
+
+
+## How to use example
+
+### Configure the project
+
+```
+idf.py menuconfig
+```
+
+### Build and Flash
+
+Build the project and flash it to the board, then run monitor tool to view serial output:
+
+```
+idf.py -p PORT flash monitor
+```
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
+
+## Example Output
+
+This console output can be observed when blehr is connected to client and client enables notifications:

+# BLE Mesh example
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+This example implements Bluetooth Mesh node that supports On/Off and Level models.
+
+It has suport for both Advertising Bearer and GATT Bearer.
+
+For more information on NimBLE MESH, please visit [NimBLE_MESH](https://mynewt.apache.org/latest/network/mesh/index.html#bluetooth-mesh).
+
+It uses ESP32's Bluetooth controller and NimBLE stack based BLE host.
+
+This example can be starting step to get basic understanding on how to build BLE MESH node.
+
+To test this demo, any BLE mesh provisioner app can be used.
+
+
+## How to use example
+
+### Configure the project
+
+```
+idf.py menuconfig
+```
+
+* Select 'Enable BLE mesh functionality' under 'Component config > Bluetooth > Enable NimBLE host stack'.
+
+### Build and Flash
+
+Build the project and flash it to the board, then run monitor tool to view serial output:
+
+```
+idf.py -p PORT flash monitor
+```
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
+
+## Example Output
+
+There is this console output on successful BLE provisioning:

+
+# BLE peripheral example
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+This example creates GATT server and then starts advertising, waiting to be connected to a GATT client.
+
+It uses ESP32's Bluetooth controller and NimBLE stack based BLE host.
+
+This example aims at understanding GATT database configuration, advertisement and SMP related NimBLE APIs.
+
+It also demonstrates security features of NimBLE stack. SMP parameters like I/O capabilities of device, Bonding flag, MITM protection flag and Secure Connection only mode etc., can be configured through menuconfig options.
+
+For RPA feature (currently Host based privacy feature is supported), use API `ble_hs_pvcy_rpa_config` to enable/disable host based privacy, `own_addr_type` needs to be set to `BLE_ADDR_RANDOM` to use this feature. Please include `ble_hs_pvcy.h` while using this API. As `ble_hs_pvcy_rpa_config` configures host privacy and sets address in controller, it is necessary to call this API after host-controller are synced (e.g. in `bleprph_on_sync` callback).
+
+To test this demo, any BLE scanner app can be used.
+
+A Python based utility `bleprph_test.py` is also provided (which will run as a BLE GATT Client) and can be used to test this example.
+
+Note :
+
+* Make sure to run `python -m pip install --user -r $IDF_PATH/requirements.txt -r $IDF_PATH/tools/ble/requirements.txt` to install the dependency packages needed.
+* Currently this Python utility is only supported on Linux (BLE communication is via BLuez + DBus).
+
+## How to use example
+
+### Configure the project
+
+```
+idf.py menuconfig
+```
+
+* Select I/O capabilities of device from 'Example Configuration > I/O Capability', default is 'Just_works'.
+
+* Enable/Disable other security related parameters 'Bonding, MITM option, secure connection(SM SC)' from 'Example Configuration'.
+
+### Build and Flash
+
+Build the project and flash it to the board, then run monitor tool to view serial output:
+
+```
+idf.py -p PORT flash monitor
+```
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
+
