These instructions have been confirmed to work on February 13, 2020 version of Raspbian Buster.
It appears "Bleacon" (the Bluetooth scanning module used in Tilt Pi) no longer appears to install succesfully regardless of nodejs version when installing on recent versions of Raspbian. As such, the module has been replaced with a "Aioblescan". These instructions were tested on a fresh install of the June 20, 2019 version of Raspbian Buster installed on a Raspberry Pi 0.
Using SSH from another computer or from a Raspberry Pi command line directly, enter the following commands. Update Raspbian packages and install python install utility, "python3-distutils".
sudo apt-get update --allow-releaseinfo-change
sudo apt-get install python3-distutils
Get the “aioblescan” bluetooth scanner module customized with Tilt plugin, unzip downloaded file, go to install folder, and install. Once you complete this step, you can run the command "sudo python3 -u -m aioblescan -T" to verify Tilt scanner is working. Make sure Tilt is nearby and floating if doing the test. Use "ctrl-c" to stop scanning.
wget https://github.com/baronbrew/aioblescan/archive/master.zip
unzip master.zip
cd aioblescan-master/
sudo -H python3 setup.py install
Install node-red update script for Raspberry Pi using version that works with Google Sheets web apps (this forked install script installs version 0.18.4 which allows following redirects of http POST requests). Answer "yes" to install Raspberry Pi specific nodes.
bash <(curl -sL https://raw.githubusercontent.com/baronbrew/raspbian-deb-package/master/resources/update-nodejs-and-nodered)
Install dashboard ui node v2.15.5 globally for node-red and enable auto-start of node-red at boot.
sudo -H npm install node-red-dashboard@2.9.7 -g
Note: For some reason v2.15.5 will not install succesfully unless v2.9.7 is installed first.
sudo -H npm install node-red-dashboard@2.15.5 -g
sudo systemctl enable nodered.service
Reboot to start node-red on boot.
sudo reboot
Download Tilt Pi “flow” that uses the new Aioblescan module
wget -O /home/pi/flow.json https://raw.githubusercontent.com/baronbrew/TILTpi/Aioblescan/flow.json
Run downloaded Tilt Pi app/flow in node-red:
curl -X POST http://localhost:1880/flows -H "Content-Type: application/json" -H "Node-RED-Deployment-Type: nodes" --data "@/home/pi/flow.json"
As an optional step, you can add a WiFi connection manager script that has a robust algorithm to maintain the WiFi connection if the connection is unstable.
curl -L wifi.brewpiremix.com | sudo bash
In a web browser visit http://raspberrypi.local:1880/ui or http://localhost:1880/ui (if not using SSH to install). If this doesn't work, you may need to find the IP address of your Raspberry Pi and go to http://X.X.X.X:1880/ui where X.X.X.X is your Raspberry Pi's IP address.
