BangleJS disconnection while streaming data

[JackHack96]

Hello!

I'm tinkering on a BangleJS project which streams sensors data to the PC (or the smartphone), based on the proposed tutorial https://www.espruino.com/Bangle.js+Data+Streaming.
Along with the accelerometers, the project also uses NRF.setScan() to send RSSI data of some BLE beacons.

On my Linux desktop PC it seems to work fine and also on my smartphone, but on a Windows PC it quickly disconnects after some seconds, both with Chrome or Edge. I also checked with another BangleJS and it's even worse.
Looking at the console log, I get this following line:

<BLE> Disconnected (gattserverdisconnected)
index-DPgjTkKc.js:14 Device disconnected or failed to connect
puck.js:409 <BLE> Disconnected (gattserverdisconnected)

right after the last print (as the example, I use Bluetooth.println() to stream data).

Could it be because of too much data? Could it be related to poor driver quality of the Windows PC?
And most importantly, is it possible to do something about this? Like some reconnection mechanism..

Thanks in advance.

Have you tried any other Windows PCs, or is it just that one PC? It could just be an issue with that one PC's bluetooth adaptor. Or it could be due to low signal strength? Are you using a Bangle.js 2?

But yes, you can reconnect. In the callback for Puck.connect(function(c) { if you're using code based on that link above, you can do:

connection.on('close', function() { 
  setTimeout(function() { // wait a small amount
    connection.reconnect(); // try a reconnect
  }, 100);
 });

and I believe that should work ok

Oh yeah sorry I forgot to mention that it's a Bangle.js 2 with last firmware.

I also think the problem could be located in the driver of that PC. I'll also test with a Windows laptop then.

Thanks
