pi-b-q

Project to programatically interact with a Thermoworks BlueTherm thermomoter.

Today this thing (sort of) does:

• Can request and interpret data from the BlueTherm
• Assumes BT connection and serial port is managed externally

Someday this thing may (or may not):

• Automatically connect to any paired BT device
• Continuously record temperature data
• Provide a web interface to view recorded and near real-time data

Installation on a Raspberry Pi

1. Start with a working, configured copy of Raspbian
2. ssh into the pi, sudo mkdir -p /var/www, cd /var/www, sudo git clone <THIS REPO>, cd pi-b-q
3. sudo pi_config/install.sh This takes eons; go get a beer.
4. Make sure you've got a working Bluetooth adapter, then use hcitool and bluetooth-agent to pair your BT
5. Update /etc/bluetooth/rfcomm.conf to map the BT to /dev/rfcomm0
6. Restart the bluetooth stack: sudo /etc/init.d/bluetooth restart

Now you can pop open a rails console and send and receive packets!

1. rvmsudo rails c (use sudo because permissions are hard)
2. serial = SerialPort.new('/dev/rfcomm0')
3. conn = BlueTherm::SerialConnection.new(serial)
4. response = conn.send(BlueTherm::Packet.default)

Some notes

Pairing

• hcitool scan shows all bluetooth devices in range; use this to get ID
• bluetooth-agent 1234 <ID> should pair the device
