Bleno installation / runtime problem

[johnrmenard]

Hi,

after many attempts at installing and running Bleno on Raspberry Pi , I get this error when running projects that have run previously:

pi@raspberrypi:~/Development/BleServer $ sudo node index.js module.js:681 return process.dlopen(module, path._makeLong(filename)); ^

Error: /home/pi/Development/BleServer/node_modules/bluetooth-hci-socket/build/Release/binding.node: wrong ELF class: ELFCLASS64 at Object.Module._extensions..node (module.js:681:18) at Module.load (module.js:565:32) at tryModuleLoad (module.js:505:12) at Function.Module._load (module.js:497:3) at Module.require (module.js:596:17) at require (internal/module.js:11:18) at Object.

This is how I installed Bleno:

sudo npm install bleno npm WARN rpi3-application@1.0.0 No description npm WARN rpi3-application@1.0.0 No repository field. npm WARN optional SKIPPING OPTIONAL DEPENDENCY: mkdirp@0.5.1 (node_modules/mkdirp): npm WARN optional SKIPPING OPTIONAL DEPENDENCY: Refusing to delete /home/pi/Development/BleServer/node_modules/usb/node_modules/node-pre-gyp/node_modules/.bin/mkdirp: is outside /home/pi/Development/BleServer/node_modules/usb/node_modules/node-pre-gyp/node_modules/mkdirp and not a link npm WARN optional SKIPPING OPTIONAL DEPENDENCY: File exists: /home/pi/Development/BleServer/node_modules/usb/node_modules/node-pre-gyp/node_modules/.bin/mkdirp npm WARN optional SKIPPING OPTIONAL DEPENDENCY: xpc-connection@0.1.4 (node_modules/xpc-connection): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for xpc-connection@0.1.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"arm"})

Make sure your RPi is up to date and has the all the dependencies installed. Make sure you're running a newer version of node.

Here's how I set up bleno on a new RPi

$ sudo apt update
$ sudo apt dist-upgrade -y

Dev tools

$ sudo apt install python-dev build-essential curl git mc -y

Bluetooth Dependencies

$ sudo apt install bluetooth bluez libbluetooth-dev libudev-dev -y

Install Nodejs (Raspberry Pi3)

$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - 
$ sudo apt install nodejs -y

The Raspberry Pi Zero W is ARM v6 and not supported by the Node.js package manager.

Download archive

$ cd ~
$ curl -O https://nodejs.org/dist/v8.9.4/node-v8.9.4-linux-armv6l.tar.xz

Install in /usr/local

$ cd /usr/local
$ sudo tar xf ~/node-v8.9.4-linux-armv6l.tar.xz

Create symlinks

$ cd /usr/local/bin
$ sudo ln -s ../node-v8.9.4-linux-armv6l/bin/node
$ sudo ln -s ../node-v8.9.4-linux-armv6l/bin/npm

Many thanks I will try this.
