CC26xx Demo
===========
This example demonstrates basic functionality for the two supported CC26xx
boards. More specifically, the example demonstrates:
* How to take sensor readings
* How to use buttons and the reed relay (triggered by holding a magnet near S3
on the SensorTag).
* How to keep a power domain powered and a peripheral clocked under low power
operation
* How to send out BLE advertisements. The device will periodically send out BLE
beacons with the platform name as payload. Those beacons/BLE ADV packets can
be captured with any BLE capable device. Two such applications for iOS are the
TI Multitool and the TI Sensortag app. They can be found in the Apple App
Store. If you have a BLE-capable Mac, you can also use LightBlue for OS X.

* Example project demonstrating the CC26xx platforms
*
* This example will work for the following boards:
* - srf06-cc26xx: SmartRF06EB + CC26XX EM
* - sensortag-cc26xx: CC26XX sensortag
*
* By default, the example will build for the srf06-cc26xx board. To switch
* between platforms:
* - make clean
* - make BOARD=sensortag-cc26xx savetarget
*
* or
*
* make BOARD=srf06-cc26xx savetarget
*
* This is an IPv6/RPL-enabled example. Thus, if you have a border router in
* your installation (same RDC layer, same PAN ID and RF channel), you should
* be able to ping6 this demo node.
*
* This example also demonstrates CC26xx BLE operation. The process starts
* the BLE beacon daemon (implemented in the RF driver). The daemon will
* send out a BLE beacon periodically. Use any BLE-enabled application (e.g.
* LightBlue on OS X or the TI BLE Multitool smartphone app) and after a few
* seconds the cc26xx device will be discovered.
*
* - etimer/clock : Every CC26XX_DEMO_LOOP_INTERVAL clock ticks the LED defined
* as CC26XX_DEMO_LEDS_PERIODIC will toggle and the device
* will print out readings from some supported sensors
* - sensors : Some sensortag sensors are read asynchronously (see sensor
* documentation). For those, this example will print out
* readings in a staggered fashion at a random interval
* - Buttons : CC26XX_DEMO_SENSOR_1 button will toggle CC26XX_DEMO_LEDS_BUTTON
* - CC26XX_DEMO_SENSOR_2 turns on LEDS_REBOOT and causes a
* watchdog reboot
* - The remaining buttons will just print something
* - The example also shows how to retrieve the duration of a
* button press (in ticks). The driver will generate a
* sensors_changed event upon button release
* - UART : Receiving an entire line of text over UART (ending
* in \\r) will cause CC26XX_DEMO_LEDS_SERIAL_IN to toggle
* This also demonstrates how a code module can influence
* low-power operation: In this example we keep the UART on
* and capable to RX even with the chip in deep sleep.
* see keep_uart_on() and the UART driver
* - Reed Relay : Will toggle the sensortag buzzer on/off

CC26xx Web Demo Readme
======================
This demo project combines a number of web-based applications aiming to
demonstrate the CC26xx capability. The applications are:
* A network-based UART
* A client for [6lbr](http://cetic.github.io/6lbr/)
* A CoAP server
* An MQTT client
* A web server which can be used to display sensor readings but also to
configure MQTT functionality
The example has been configured to run for both CC26xx-based boards: i) The
SensorTag 2.0 and ii) The Srf06EB with a CC26xx EM mounted on it.
To build the example for the Srf, simply run `make`. To build for the tag,
run `make BOARD=sensortag`. Do not forget to `make clean` when switching
between the two platforms.
You can disable some of those individual components by changing the respective
defines in `project-conf.h`. For instance, to disable the CoAP functionality,
set `#define CC26XX_WEB_DEMO_CONF_COAP_SERVER 0`. The web server cannot be
disabled, all other aforementioned applications can.
Network UART (net-uart)
-----------------------
This example only makes sense if you are using the Srf or if you have taken
the sensortag out of its case and you have it connected over JTAG to the Srf.
The net-uart does two things:
* When you type a string to the UART console, the string will be sent verbatim
to a remote UDP port 7777 listener. This can be for example a netcat listener
on a linux or OS X PC:
`nc -6ulkw 1 7777`
* The net-uart also listens to UDP port 7777 and when it receives a string over
UDP, it will print it verbatim over UART.
The example will initially send packets to a hard-coded IPv6 address. This can
be changed very easily by entering a different IPv6 address to the console.
Thus, when the serial input string is an IPv6 address, it will not be sent as
any other string would, but instead it will configure the example to send to a
different remote address. This new IPv6 address is not persistent across
device reboots.
6lbr Client
-----------
This will periodically send a UDP packet to your 6lbr, containing network
information, which will be used by 6lbr to construct a network graph. To see
this in action, fire up a browser and navigate to the 6lbr web page. The
default address is http://[bbbb::100]. Once the page loads, click the 'sensors'
tab, as per the image below.
![6lbr](img/6lbr-web.png)
CoAP Server
-----------
For this functionality to work, you will need to install the
[Copper (Cu)](https://addons.mozilla.org/en-US/firefox/addon/copper-270430/)
addon to your browser.
From the sensors tab in the 6lbr web page, click the 'coap' link in the line
corresponding to your CC26xx device. Once the addon fires up, select
".well-known/core" in the left pane and then hit the 'Get' button at the top.
![CoAP Resources](img/coap-resources.png)
The Device will respond with a list of all available CoAP resources. This list
will be different between the Srf and the SensorTag. The screenshot below shows
a (partial) list of resources exported by the SensorTag CoAP server. Select
a resource on the left pane and hit 'Get' to retrieve its value. Select
`lt/g` and hit 'Post' to toggle the green LED, `lt/r` for the red one.
You can also use CoAP to enable/disable BLE advertisements! Select
`dev/ble_advd` and then hit the "Outgoing" button in the payload panel. Type in
the desired payload, which can be:
* `mode=on|off`
* `name=<name>`
* `interval=<secs>`
or a combination of both delimited with an amp. For example, you can set as
payload `mode=on&name=My CC26xx Device 4&interval=5`. Once you have set the
payload, hit either the POST or PUT button.
Bear in mind that you must set `name` at least once before enabling BLE
advertisements. If you fail to do so, the RF will refuse to enter BLE mode and
the CoAP engine will return 4.03 forbidden. The values of `name` and `interval`
persist across BLE on/off cycles, so you only have to set them once. The values
do _not_ persist through device powercycles.
HTTPD
-----
Back on the 6lbr page, hit the 'web' link corresponding to your device. This
will take you to a web page served by the CC26xx. The HTTPD serves two pages:
* index.html: Provides sensor readings and network information
* config.html: Can be used to configure the MQTT client (more below)
In the navigation bar at the top there is also a third link, which will take
you directly to your device's page on IBM's quickstart service.
IBM Quickstart / MQTT Client
----------------------------
The MQTT client can be used to:
* Publish sensor readings to an MQTT broker.
* Subscribe to a topic and as a result receive commands from an MQTT broker
The device will try to connect to IBM's quickstart over NAT64, so you will
need a NAT64 gateway in your network to make this work. A guide on how to
setup NAT64 is out of scope here. If this is not an option for you, you can
configure the device to publish to a local MQTT broker over end-to-end IPv6.
See below on how to change the destination broker's address.
By default the device will publish readings to IBM's quickstart service. The
publish messages include sensor readings but also some other information such
as device uptime in seconds and a message sequence number. Click the "IBM
Quickstart" link in the web page to go directly to your device's page
on Quickstart. After a few seconds, you will see something like this:
![A SensorTag on IBM Quickstart](img/quickstart-sensortag.png)
Sensor readings are only published if they have changed since the previous
reading (BatMon is an exception and always gets published). Additionally, you
can turn on/off individual readings from the config.html web page, as per the
figure below.
![Sensor Readings Configuration](img/sensor-readings-config.png)
Some of the MQTT client functionality can be configured even further:
* You can change the broker IP and port. This is useful if you want to use your
own MQTT broker instead of IBM's quickstart. The example has been tested
successfully with [mosquitto](http://mosquitto.org/)
* You can change the publish interval. Recommended values are 10secs or higher.
You will not be allowed to set this to anything less than 5 seconds.
* If you want to use IBM's cloud service with a registered device, change
'Org ID' and provide an 'Auth Token', which acts as a 'password', but bear in
mind that it gets transported in clear text, both over the web configuration
page as well as inside MQTT messages.
* The remaining configuration options are related to the content of MQTT
messages and in general you won't have to modify them.
For the SensorTag, changes to the MQTT configuration get saved in external
flash and persist across device restarts. The same does not hold true for
Srf+EM builds.
You can also subscribe to topics and receive commands, but this will only
work if you use "Org ID" != 'quickstart'. Thus, if you provide a different
Org ID (do not forget the auth token!), the device will subscribe to:
`iot-2/cmd/+/fmt/json`
You can then use this to toggle LEDs or to turn the buzzer on and off.
The buzzer is only available on the SensorTag. To do this, you can for example
use mosquitto client to publish to `iot-2/cmd/leds/fmt/json`. So, to turn
the buzzer on, you would do this:
`mosquitto_pub -h <broker IP> -m "1" -t iot-2/cmd/buzz/fmt/json`
Where `broker IP` should be replaced with the IP address of your mosquitto
broker (the one where you device has subscribed). Replace `-m "1'` with `-m "0"`
to turn the buzzer back off. Replace `buzz` with `leds` in the topic to change
the state of the LED.
Bear in mind that, even though the topic suggests that messages are of json
format, they are in fact not. This was done in order to avoid linking a json
parser into the firmware.

* A process which receives data over UART and transmits them over UDP
* to a pre-defined IPv6 address and port. It also listens on the same UDP
* port for messages, which it prints out over UART.
*
* For this example to work, you will have to modify the destination IPv6
* address by adjusting the set_dest_addr() macro below.
*
* To listen on your linux or OS X box:
* nc -6ulkw 1 REMOTE_PORT
*
* (REMOTE_PORT should be the actual value of the define below, e.g. 7777)
*
* Once netcat is up and listening, type something to the CC26xx's terminal
* Bear in mind that the datagram will only be sent after a 0x0a (LF) char
* has been received. Therefore, if you are on Win, do NOT use PuTTY for
* this purpose, since it does not send 0x0a as part of the line end. On
* Win XP use hyperterm. On Win 7 use some other software (e.g. Tera Term,
* which can be configured to send CRLF on enter keystrokes).
*
* To send data in the other direction from your linux or OS X box:
