Unhandled 'error' event when running simpleBeacon.js
Closed this issue · 2 comments
Hi,
I was just testing simpleBeacon.js and see how Physical Web works and I am stuck at one point. Could you please point out whre I might be going wrong??
First my configuration:
OS: Ubuntu 12.04 LTS 32 bit
RAM:2GB
Nodejs version: v0.10.33
NPM version: 1.4.28
1)So I basically downloaded the repository using git clone in my home directory:
git clone git clone https://github.com/don/node-uri-beacon.git
2)Changed to directory
cd node-uri-beacon
3)Then I used install command
npm install
4)Then ran test command
npm test

5)Assuming everything is OK, I changed directory to examples
cd examples
6)Ran simpleBeacon.js
sudo nodejs simpleBeacon.js
got following error:
events.js:72
throw er; // Unhandled 'error' event

@simishu07 I'd guess this is a problem with an old version of bluez or unsupported BLE hardware.
Can you see if you can connect to a BLE device using bluez?
Try something like this
chronos@localhost / $ hcitool dev

Assuming Ubuntu 12.04 or bluez was too old. Closing since no response.
