Hello,

After multiple attempts, I'm turning towards you... I'm trying to use my TI sensortag on Node-Red but it keeps hanging on "discovering..."

My sensortag is up and the info on it (physical sticker) is:  
1.7.2.8  
BLE  
Rsv 1.5.0  
Rsv 1.4.2

Using Mac OS 10.14.4  
Node-RED version: v0.20.3  
Node.js version: v11.12.0

Please tell me what information you need to understand my issue! 😉  
(screen capture, logs, etc..)  
Many thanks

Thank you very much, now using the following but same issue still...

[info] Node-RED version: v0.20.3  
[info] Node.js version: v10.15.3

(Changed Node version, rebuilt node-red-node-sensortag as it was compiled against node v11, relaunched node-red and redeployed)

did you read the prereq's?

## Pre-requisites

You will need a suitable Bluetooth Low Energy (BLE) stack and drivers for your hardware

- for example Bluez 5.2.x or better.

I did read pre-requisites and checked my macbook's bluetooth stack was compatible.  
However, I tried to find another compatible BLE stack but was unable to find one... if you could point smth at me on this one 😉  
Thanks

Sorry, I've never used it, I just wanted to make sure you had done the prerequisites

Have you tried node-red-piervin-sensortag?

Thanks for the hand! 😉

I have tried but unfortunately falling on this error when launching node-red:  
[node-red-piervin-sensortag/sensorTagWithBattery] Error: Cannot find module './build/Release/binding.node'

I have searched for a fix and somehow node-gyp compilation is failing. I thing I should use latest version of node modules instead of the ones specified. (edit package.json)  
I'll try that tomorrow...

Anyone has ideas for the standard node ? (should I open an issue on Github? [probably too early])

looking at the compile errors I suspect you may need to drop back to node 8.x (if you are lucky).
