  Great idea. It worked now using "AT+CBC\r" for comparison. Thank you. Then you get these values: [bcs, bcl, voltage]
  The second one (bcl) returns the battery charge level in percent. So it is exactly what I wanted. By the way bcs shows if the battery is charging. I guess that this is the most elegant way to get the battery level.

  The output is "CBC is AT+CBC", so it did not work unfortunately.

  Having said all that it looks like the BG96 may itself have a battery level monitor. I think if you send the AT command AT+CBC it'll give you a battery charge value.
  @Gordon I have tried to use the command this way:

  var at = require("AT").connect(Serial3);  
  at.debug();
  
  at.cmd("AT+CBC\r\n", 1000, function(d) {
    if (d===undefined) ; 
    console.log("DATA"+d);
  });
  

  Unfortunately it only returns undefined. Should I use another module or what might cause this error?

  You wrote that you are updating the firmware using USB. Did you already try this for the RAK8212? And how do you do this? Are you using the Adaptor Board and QFlash?

  Now it is Version 6. I did not find a newer version.

  I had a website like this (http://partone-domain.de). I figured out that the dash (-) caused the problem. When I hosted the zip on a domain without a dash in the URL it worked well.

  I tried many things but now I only get the HTTPEND 701 error (which means unknown HTTP(s) error). After HTTPSTART it returns OK.
  My code:

  gprs.at.cmd("AT+QFOTADL=\"https://www.my­domain.de:443/update.zip\"\r\n",1000,pri­nt);
  

  I tried many things like setting the port, changing the domain to http, removing the ", but nothing did work. I downloaded the zip provided on RAK's website. Any idea how to deal with this error?

  I tried this:

  require('QuectelBG96').connect(usart, {
        apn : "web.vodafone.de",
        username : "vodafone",
        password : "vodafone"
      }, function(err) {
        console.log("Connected!");
        if (err) throw err;
        gprs.at.cmd('AT+QFOTADL="http://mydomain­.de/update.zip"',1000,print);
  

  But how do I know that it worked? There is no console output. Or how much time does it need? Kind regards

  Might this solve the problem? Updating the BG96 firmware? There is a new post on RAK8212 website:

  @Gordon This would be a great improvement for the future adding this AT-Command to Espruino. This could fix the problems mentioned in this thread.
