TCup Sensor

TCup helps you improve the quality of your tea consumption, by adapting the infusion process accordingly to the type of tea, and by notifying you when your cup of tea has arrived to your favorite drinking temperature.

Source code of the Iphone client: TCup-iOS

Alternatively, this server also serves a web client to control the sensor. Just open http://edison.local:1337 in your web browser as the server is running on your Intel Edison device.

TemperatureSensor reads analog data from a Grover Starter Kit Plus – IoT Intel® Edition Temperature Sensor.

Usage instructions

• Assemble the hardware, by following the instructions on the TCup instructables page
• Push this project to your Intel Edison board
• Install the dependencies: npm install
• Run the server on the board: node main.js
• Open http://edison.local:1337 in your web browser for testing.

Adding Bluetooth Pairing

So far, and as explained on the instructables page, the IP address of the Edison board must be entered in the iOS client's source code, because no device discovery/pairing mechanisms have been successfully tested for this project yet.

However, we started to integrate some Bluetooth pairing code from Intel's samples.

If you want to enable Bluetooth pairing:

• uncomment the corresponding code from this project,
• add the corresponding npm dependencies,
• and follow the instructions below.

It uses bleno on Intel IoT platforms to advertise it's presence, to read and write data via it's service and corresponding characteristic for Bluetooth Low Energy (BLE) communication.

In order to leverage this project successfully, you will need:

• to use a compatible BLE product such as the Grove - BLE,
• to enable bluetooth and disable the bluetooth daemon on Intel(R) Edison,
• to run the client on your mobile phone.

First time - Enabling BLE

Within a SSH or Serial Terminal connection, type the following commands,

rfkill unblock bluetooth 
hciconfig hci0 up

vi /etc/opkg/base-feeds.conf (insert only following lines) 
src/gz all http://repo.opkg.net/edison/repo/all 
src/gz edison http://repo.opkg.net/edison/repo/edison 
src/gz core2-32 http://repo.opkg.net/edison/repo/core2-32

For more information on the vi editor, visit http://www.cs.colostate.edu/helpdocs/vi.html

opkg update 
opkg install bluez5-dev

Note: If bluez fails to install this version, still proceed with remainding steps.

Prerequisite for Bleno - node package to work successfully

Note: The following steps will need to be executed every time the board is restarted. Within a SSH or Serial Terminal connection, type the following commands,

rfkill unblock bluetooth 
killall bluetoothd (or, more permanently) systemctl disable bluetooth 
hciconfig hci0 up 

You should now be able to use BLE in your project.
