Big gaps between estimote stickers package reception on Macbook

[guillaumedenece]

Hi everyone!

When I run a simple code on my macbook air to detect the sticker package, there are big gap of 2 or 3 minutes during which I don’t receive anything, and I then receive packages each 2 or 3 seconds, and then there is an other gap… I precise that there is only one sticker in range when I run my code. How can we explain it? And how is it possible to delete those gaps? Other question: Why does the package are not received regularly (1, 2 or 3 seconds) when there is no gap instead of the amount of time specified in the package interval setting of nearable package (when it is not in motion) ?

Thank you !

Guillaume

Here are the emission settings of my stickers: Nearable: Advertising interval (still): 1487ms Advertising interval (motion): 743ms

Estimote: Advertising interval (still): 5948ms Advertising interval (motion): 2974ms

Here is the code I’m running: (Node.js)

var i=0;

var EstimoteSticker = require('./estimote-sticker');

EstimoteSticker.on('discover', function(estimoteSticker) { if(estimoteSticker.id == "dd1abfef45fe6614") { i++; console.log(""); console.log(Date()); console.log(i); } });

var uuid = "D0D3FA86-CA76-45EC-9BD9-6AF4659A0A3D"; EstimoteSticker.startScanning(uuid);

And here is the log I obtain after running my code for a couple of minutes:

@guillaumedenece I suggest you look at the PacketLogger app which is part of Xcode hardware IO tools. It'll allow you to trace what the HCI adapter is reporting.
