+## BLE connection and time synchronization
 At runtime, BLE advertising is started. You can then use a smartphone or computer to connect and bond to your Pinetime. 
 As soon as a device is bonded, Pinetime will look for a **CTS** server (**C**urrent **T**ime **S**ervice) on the connected device.

     - Select server configuration "Current Time Service" and tap OK
 * Go back to the main screen and scan for BLE devices. A device called "PineTime" should appear
 * Tap the button "Connect" next to the PineTime device. It should connect to the PineTime and switch to a new tab.
-* On this tab, on the top right, there is a 3 dots button. Tap on it and select Bond. The bonding process begins, and if it is sucessful, the PineTime should update its time and display it on the screen.
+* If a CTS server is found, the Pinetime should update its time with the time provided by the server.
 
 ### Using Linux and bluetoothctl
 * Ensure that your bluetooth controller is enabled and working fine. I've tested this on a x86 Debian computer and on a RaspberryPi 3.

+# Coding Style for Apache NimBLE
+
+Apache NimBLE project is part of Apache Mynewt projct and follows its coding
+style.
+
+# Coding Style for Apache Mynewt Core
+
+This document is meant to define the coding style for Apache Mynewt, and
+all subprojects of Apache Mynewt.  This covers C and Assembly coding
+conventions, *only*.  Other languages (such as Go), have their own
+coding conventions.
+
+## Headers
+
+* All files that are newly written, should have the Apache License clause
+at the top of them.
+
+* For files that are copied from another source, but contain an Apache
+compatible license, the original license header shall be maintained.
+
+* For more information on applying the Apache license, the definitive
+source is here: http://www.apache.org/dev/apply-license.html
+
+* The Apache License clause for the top of files is as follows:
+
+```no-highlight
+/*
+ * Licensed to the Apache Software Foundation (ASF) under one
+ * or more contributor license agreements.  See the NOTICE file
+ * distributed with this work for additional information
+ * regarding copyright ownership.  The ASF licenses this file
+ * to you under the Apache License, Version 2.0 (the
+ * "License"); you may not use this file except in compliance
+ * with the License.  You may obtain a copy of the License at
+ *

+ * software distributed under the License is distributed on an
+ * "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+ * KIND, either express or implied.  See the License for the
+ * specific language governing permissions and limitations
+ * under the License.
+ */
+```
+
+## Whitespace and Braces
+
+* Code must be indented to 4 spaces, tabs should not be used.
+
+* Do not add whitespace at the end of a line.
+
+* Put space after keywords (for, if, return, switch, while).
+
+* for, else, if, while statements must have braces around their
+code blocks, i.e., do:
+
+```
+    if (x) {
+        assert(0);
+    } else {
+        assert(0);
+    }
+```
+
+Not:
+
+```
+    if (x)
+        assert(0);
+    else
+        assert(0);
+```
+
+* Braces for statements must be on the same line as the statement.  Good:
+
+```
+    for (i = 0; i < 10; i++) {
+        if (i == 5) {
+            break;
+        } else {
+            continue;
+        }
+    }
+```
+
+Not:
+
+```
+    for (i = 0; i < 10; i++)
+    { <-- brace must be on same line as for
+        if (i == 5) {
+            break;
+        } <-- no new line between else
+        else {
+            continue;
+        }
+    }
+```
+
+* After a function declaration, the braces should be on a newline, i.e. do:
+
+```
+    static void *
+    function(int var1, int var2)
+    {
+```
+
+not:
+
+```
+    static void *
+    function(int var1, int var2) {
+```
+
+## Line Length and Wrap
+
+* Line length should never exceed 79 columns.
+
+* When you have to wrap a long statement, put the operator at the end of the
+  line.  i.e.:
+
+```
+    if (x &&
+        y == 10 &&
+        b)
+```
+
+Not:
+
+```
+    if (x
+        && y == 10
+        && b)
+```
+
+## Comments
+
+* No C++ style comments allowed.
+
+* When using a single line comment, put it above the line of code that you
+intend to comment, i.e., do:
+
+```
+    /* check variable */
+    if (a) {
+```
+
+Not:
+
+```
+    if (a) { /* check variable */
+```
+
+
+* All public APIs should be commented with Doxygen style comments describing
+purpose, parameters and return values.  Private APIs need not be documented.
+
+
+## Header files
+
+* Header files must contain the following structure:
+    * Apache License (see above)
+    * ```#ifdef``` aliasing, to prevent multiple includes
+    * ```#include``` directives for other required header files
+    * ```#ifdef __cplusplus``` wrappers to maintain C++ friendly APIs
+    * Contents of the header file
+
+* ```#ifdef``` aliasing, shall be in the following format, where
+the package name is "os" and the file name is "callout.h":
+
+```no-highlight
+#ifndef _OS_CALLOUT_H
+#define _OS_CALLOUT_H
+```
+
+* ```#include``` directives must happen prior to the cplusplus
+wrapper.
+
+* The cplusplus wrapper must have the following format, and precedes
+any contents of the header file:
+
+```no-highlight
+#ifdef __cplusplus
+#extern "C" {
+##endif
+```
+
+## Naming
+
+* Names of functions, structures and variables must be in all lowercase.
+
+* Names should be as short as possible, but no shorter.
+
+* Globally visible names must be prefixed with the name of the module,
+followed by the '_' character, i.e.:
+
+```
+    os_callout_init(&c)
+```
+
+Not:
+
+```
+    callout_init(c)
+```
+
+## Functions
+
+* No spaces after function names when calling a function, i.e, do:
+
+```
+    rc = function(a)
+```
+
+Not:
+
+```
+    rc = function (a)
+```
+
+
+* Arguments to function calls should have spaces between the comma, i.e. do:
+
+```
+    rc = function(a, b)
+```
+
+Not:
+
+```
+    rc = function(a,b)
+```
+
+* The function type must be on a line by itself preceding the function, i.e. do:
+
+```
+    static void *
+    function(int var1, int var2)
+    {
+```
+
+Not:
+
+```
+    static void *function(int var1, int var2)
+    {
+```
+
+* In general, for functions that return values that denote success or error, 0
+shall be success, and non-zero shall be the failure code.
+
+## Variables and Macros
+
+* Do not use typedefs for structures.  This makes it impossible for
+applications to use pointers to those structures opaquely.
+
+* typedef may be used for non-structure types, where it is beneficial to
+hide or alias the underlying type used (e.g. ```os_time_t```.)   Indicate
+typedefs by applying the ```_t``` marker to them.
+
+* Place all function-local variable definitions at the top of the function body, before any statements.
+
+## Compiler Directives
+
+* Code must compile cleanly with -Wall enabled.

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "{}"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+
+## Overview
+
+Apache NimBLE is an open-source Bluetooth 5.1 stack (both Host & Controller)
+that completely replaces the proprietary SoftDevice on Nordic chipsets. It is
+part of [Apache Mynewt project](https://github.com/apache/mynewt-core).
+
+Features highlight:
+  - Support for 251 byte packet size
+  - Support for all 4 roles concurrently - Broadcaster, Observer, Peripheral and Central
+  - Support for up to 32 simultaneous connections.
+  - Legacy and SC (secure connections) SMP support (pairing and bonding).
+  - Advertising Extensions.
+  - Coded (aka Long Range) and 2M PHYs.
+  - Bluetooth Mesh.
+
+## Supported hardware
+
+Controller supports Nordic nRF51 and nRF52 chipsets. Host runs on any board
+and architecture [supported](https://github.com/apache/mynewt-core#overview)
+by Apache Mynewt OS.
+
+
+## Browsing
+
+If you are browsing around the source tree, and want to see some of the
+major functional chunks, here are a few pointers:
+
+- nimble/controller: Contains code for controller including Link Layer and HCI implementation
+([controller](https://github.com/apache/mynewt-nimble/tree/master/nimble/controller))
+
+- nimble/drivers: Contains drivers for supported radio transceivers (Nordic nRF51 and nRF52)
+([drivers](https://github.com/apache/mynewt-nimble/tree/master/nimble/drivers))
+
+- nimble/host: Contains code for host subsystem. This includes protocols like
+L2CAP and ATT, support for HCI commands and events, Generic Access Profile (GAP),
+Generic Attribute Profile (GATT) and Security Manager (SM).
+([host](https://github.com/apache/mynewt-nimble/tree/master/nimble/host))
+
+- nimble/host/mesh: Contains code for Bluetooth Mesh subsystem.
+([mesh](https://github.com/apache/mynewt-nimble/tree/master/nimble/host/mesh))
+
+- nimble/transport: Contains code for supported transport protocols between host
+and controller. This includes UART, emSPI and RAM (used in combined build when
+host and controller run on same CPU)
+([transport](https://github.com/apache/mynewt-nimble/tree/master/nimble/transport))
+
+- porting: Contains implementation of NimBLE Porting Layer (NPL) for supported
+operating systems
+([porting](https://github.com/apache/mynewt-nimble/tree/master/porting))
+
+- ext: Contains external libraries used by NimBLE. Those are used if not
+provided by OS
+([ext](https://github.com/apache/mynewt-nimble/tree/master/ext))
+
+- kernel: Contains the core of the RTOS ([kernel/os](https://github.com/apache/mynewt-core/tree/master/kernel/os))
+
+## Sample Applications
+
+There are also some sample applications that show how to Apache Mynewt NimBLE
+stack. These sample applications are located in the `apps/` directory of
+Apache Mynewt [repo](https://github.com/apache/mynewt-core). Some examples:
+
+* [blecent](https://github.com/apache/mynewt-nimble/tree/master/apps/blecent):
+A basic central device with no user interface.  This application scans for
+a peripheral that supports the alert notification service (ANS). Upon
+discovering such a peripheral, blecent connects and performs a characteristic
+read, characteristic write, and notification subscription.
+* [blehci](https://github.com/apache/mynewt-nimble/tree/master/apps/blehci):
+Implements a BLE controller-only application.  A separate host-only
+implementation, such as Linux's BlueZ, can interface with this application via
+HCI over UART.
+* [bleprph](https://github.com/apache/mynewt-nimble/tree/master/apps/bleprph): An
+  implementation of a minimal BLE peripheral.
+* [btshell](https://github.com/apache/mynewt-nimble/tree/master/apps/btshell): A
+  shell-like application allowing to configure and use most of NimBLE
+  functionality from command line.
+* [bleuart](https://github.com/apache/mynewt-core/tree/master/apps/bleuart):
+Implements a simple BLE peripheral that supports the Nordic
+UART / Serial Port Emulation service
+(https://developer.nordicsemi.com/nRF5_SDK/nRF51_SDK_v8.x.x/doc/8.0.0/s110/html/a00072.html).
