• Are there ways to increase bluetooth range in reading the advertisement?

  Thanks. Yes, I'm using WiFi currently. Maybe I can try using a separate WiFi dongle, and see if that improves the Bluetooth? I wouldn't have thought to do that. I've got a spare one I can try.

  I found it was pretty hard to buy long range Bluetooth LE dongles anywhere.

  I spent a while looking into it and found a couple of things on eBay, but there's no way of knowing how much, if any improvement I'll see.

  I guess I'll try the separate Wifi dongle, and if that doesn't work I'll probably just get the one you're selling. Thanks.

  Hi. I'm hoping to be able to increase the range on the Raspberry Pi Zero that I'm running EspruinoHub on. And that should mean I can place devices further away, right?

  Is the dongle being sold in the Espruino store the best option? Does anyone have any experience of it making an improvement to their range? Or are there other options?

  Thanks.

  @parasquid thanks for explaining that. I totally missed it, somehow.

  I guess I need to find those parts for the potential divider. I'll report back if I get something working...

  Hmm. NRF.getBattery() says 3.27 for my LiPo, but my voltmeter says 4.08.

  Thanks. Yes, I'm using the breakout board.

  So, with the potential divider, you're just measuring the voltage of the battery? What's the difference between that and using NRF.getBattery()?

  I've got an MDBT42Q connected to a LiPo battery. Is there any way to calculate the percentage of the battery that's remaining? The build-in function only works for Puck, Pixl and Bangle.

  Can I do something similar to what they have?

  JsVarInt jswrap_puck_getBattery() {
    JsVarFloat v = jshReadVRef();
    int pc = (v-2.2)*100/0.6;
    if (pc>100) pc=100;
    if (pc<0) pc=0;
    return pc;
  }
  

  Thanks.

  What would happen if another app or widget also called NRF.setAdvertising()? Would one overwrite the other? I can see that being a problem.
