Unable to install with Node-Red

[ram1505]

Hi,
I'm unable to install this with my node-red. Here is the error I get when I try installing:

Failed to execute '/usr/bin/nodejs /usr/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js build --fallback-to-build --target_arch=x64 --mo dule=/home/demo/.node-red/node_modules/node-red-contrib-lwm2m/dist/binding/node-v48-linux-x64/node_lwm2m.node --module_name=node_lwm2m --modul e_path=/home/demo/.node-red/node_modules/node-red-contrib-lwm2m/dist/binding/node-v48-linux-x64' (1) npm WARN node-red-project@0.0.1 No repository field. npm WARN node-red-project@0.0.1 No license field. npm ERR!

For linux-x64, you need to install GCC/make on your computer in order to compile C/C++ code. npm and node-gyp don't perform GCC/make installation, so please install them manually.

[ram1505]

I've both GCC/make installed on my Mac and I still cannot install this node.

[dbaba]

As long as I looked at your error message, you were trying to install the node on Linux rather than mac. If you're installing it on mac, it should work.
Are you using Docker, Vagrant or other VMs?

[ram1505]

Ok, the initial error message I posted was on my Linux production machine. However, I did try installing node-red on my local machine (Mac) to test it out and still not able to install using npm. Is there a different way I need to install this? No, I'm not using any docker or other VMs.

Here are my GCC/ make versions

Weird. Could you tell me the following command results?

$ node -v
$ npm -v
$ node -e 'console.log(require("os").arch())'
$ uname -a

[ram1505]

node -v
v6.11.2
npm -v
3.10.10
node -e 'console.log(require("os").arch())'
x64
uname -a
Linux 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u5 (2017-09-19) x86_64 GNU/Linux

[dbaba]

Okay, I've uploaded prebuilt binaries for Linux x64.
Try npm install again or the palette manager on NR UI and let me know if it works for you. I will include the Linux-x64 prebuilt binaries for further release if successful.

[ram1505]

Awesome! I can successfully install now. Thanks @dbaba

[ram1505]

Hey, is there a sample flow that can be used for getting started and to understand the node?

[dbaba]

You can import an example flow from the menu icon, Import -> Examples -> lwm2m -> 01.basic-operations. I also published a step-by-step tutorial here.

[ram1505]

Great! Managed to get it work with the example. However, I'm having trouble getting the server to connect when I've a NB-IoT module with my Raspberry Pi. The module already attached to network. Any idea how to make it work over NB-IoT? I'm using SIMCOM 7000C module.

[dbaba]

Sounds interesting. Unfortunately, I've never tried NB-IoT as no carriers are yet operating it...
But the node should work if your RPi is connecting to internet.
I'd tried it with a LTE CAT.1 module on my RPi and it worked fine.
Are you trying to connect Leshan sandbox? Can you do that?

[ram1505]

It's a bit different with LTE Cat1. Some NB modules support only UDP. I'm checking with the module vendor on this. Will keep you posted here. I did try my RPi with Leshan sandbox server and it worked great. Thanks for this great work!

[dbaba]

Mmm, very interesting. I'm looking forward to hearing the updates! I'd like to look into NB-IoT and LTE-M as well, but here in Japan, I can't. Some of carriers say they will launch soon but I'm not sure when it is 😩

[ram1505]

Hey, I finally figured out how to use a NB-IoT/ CAT-M1 module connected to a raspberry pi. Basically yo got to set up a ppp chat script. I followed the steps stated here and got the LWM2M client access over NB-IoT/ CAT-M1. http://sixfab.com/updated-tutorial-2-make-a-ppp-internet-connection-with-sixfab-gprs-shield-on-raspberry-pi/

[ram1505]

Do you have more examples? When I try to write to for example /3/0/1 I get the following error:

{"status":132,"message":"Not Found","operation":"write","uri":"/3/0/1","value":"ABC123"}

[dbaba]

Thanks for the info. I understood where you got stuck.
Regarding the error, uncheck Hide Sensitive Device Info on the lwm2m configuration dialog.
The following resources are hidden by default so that they're not sent unexpectedly to the public sandbox server.

• Model Number (ID:1)
• Serial Number (ID:2)
• Firmware Version (ID:3)
