+ * Packages outside of RIOTPKG
+ * ---------------------------
+ * It can be beneficial to create packages outside of the RIOT tree. For example
+ * if one is working on new packages that aren't ready to be committed to
+ * upstream or if an application needs its own unique packages. For this, one
+ * can use the `EXTERNAL_PKG_DIRS` make variable. It works similar to the way
+ * [external modules](src/creating-modules.html#modules-outside-of-riotbase) are
+ * handled. In your application's Makefile, in addition to adding the package
+ * name to `USEPKG` as shown above, add the path to a folder that contains your
+ * external packages:
+ *
+ * ~~~~~~~~ {.mk}
+ * EXTERNAL_PKG_DIRS += <PATH_TO_FOLDER_CONTAINING_PACKAGES>
+ * ~~~~~~~~
+ *
+ * The path is allowed to be relative to the application's directory.
+ *
+ * ***NOTE:*** The name of an external package must be unique (both in regard to
+ * other external packages, as well to native RIOT packages). Additionally, the
+ * directory containing the packages must match the package name, e.g. package
+ * `foo`must be located in `<PATH_IN_EXTERNAL_PKG_DIRS>/foo`.
+ *
+ * An example can be found in
+ * [`tests/external_pkg_dirs`](https://github.com/RIOT-OS/RIOT/tree/master/tests/external_pkg_dirs)
+ *
+ * RIOT welcomes new and useful packages. If you'd like to share your work,
+ * consider [contributing](https://github.com/RIOT-OS/RIOT/tree/master/CONTRIBUTING.md).

+# STDIO NimBLE
+
+This module uses NimBLE for stdio. The bluetooth characteristic for
+stdin is writable and the characteristic for stdout uses the indicate
+mechanism to publish the system's output to a connected device. Data will be
+sent out asynchronously via callout functions.
+
+To use this module, add
+```
+USEMODULE += stdio_nimble
+```
+to your makefile.
+
+You can change the default buffer sizes by adding
+```
+CFLAGS += -DCONFIG_STDIO_NIMBLE_STDIN_BUFSIZE=1024
+CFLAGS += -DCONFIG_STDIO_NIMBLE_STDOUT_BUFSIZE=2048
+```
+to your makefile. \
+**NOTE:** These values must be a power of two!
+
+By default, stdin and stdout buffers are cleared on a connect event. To keep the
+content add the following to your makefile:
+```
+CFLAGS += -DCONFIG_STDIO_NIMBLE_CLEAR_BUFFER_ON_CONNECT=0
+```
+
+For automatic bluetooth advertising a module is provided: *nimble_autoadv*.
+It will take care of enabling advertising on disconnect events and
+disabling advertising on connect events. It can be enabled by adding
+```
+USEMODULE += nimble_autoadv
+```
+to your makefile.
+
+The advertised device name can then optionally be configured with
+```
+CFLAGS += -DNIMBLE_AUTOADV_DEVICE_NAME='"Riot OS device"'
+```
+Otherwise the device will appear as "*RIOT OS device*".
+
+## Instructions to connect to the bluetooth shell via ble-serial
+
+- Configure and compile shell app for nrf52840dongle target in `tests/shell`.\
+
+Add following to Makefile:
+```
+BOARD = nrf52840dongle
+USEMODULE += nimble_autoadv
+USEMODULE += stdio_nimble
+```
+
+**NOTE:** You can also have a look at `tests/shell_ble`.
+
+- Flash
+
+`$ make -C tests/shell -j clean all flash`
+
+- Install the ble-serial tool
+
+`$ pip install ble-serial`
+
+- Scan for your device (device name `Riot OS device`) and note its BLE address.\
+  When you get `ble-scan: command not found` you can also run
+  `python -m ble_serial.scan` instead.

 # Usage
 Just enter the `make BOARD=??? flash` command in the `tests/driver_lc709203F/` folder.
-Make sure the `LC709203F_INT_PIN` is set in your boards periph_conf.h
+Make sure the `LC709203F_PARAMS_ALARM_PIN` is set in your boards `board.h`
 # Results
 The sensor will first test the low RSOC interrupt by setting the threshold limit to 100%. Therefore a low RSOC interrupt should be triggered and the message "ALARM low RSOC" should be printed to the terminal. After that all major measurements will be printed and refreshed every 5s.

+external_pkg_dirs
+=================
+
+Test application for the EXTERNAL_PKG_DIRS feature of the buildsystem.
+Two external packages are provided in `external_pkgs/`: `external_pkg` and
+`external_pkg_not_used`. If the first package is not properly included, a define
+from `CFLAGS` is missing and a precompiler error is triggered. If the second
+package somehow ends up included it triggers a makefile error.
+
+Usage
+=====
+
+Set `EXTERNAL_PKG_DIRS` inside Makefile to point to other paths where the
+buildsystem can look for packages. Similar functionality to `EXTERNAL_PKG_DIRS`.
+Be careful to not name these externally provided packages the same as existing
+packages in `$(RIOTBASE)/pkg/`.
