  Seems like the instability and incorrect values were caused by bad connections. I soldered it, and now it all works without problems..

  Sorry for the ruckus.

  Interesting, did not know that. But no, other pins also have the same issue. Same behaviour with hardware I2C (error Error 33281) and software I2C (weird readings) using different pins.

  Hi.

  I'm trying to get a BME280 working using I2C.

  I can't seem to get it to work on my Pixl.js

  Using the hardware I2C like this:

  var BME = require("BME280");
  I2C1.setup({scl:A5,sda:A4});
  var bme = BME.connect(I2C1, { addr: 0x76 });
  console.log(bme.getData());
  

  I'm getting this error

  Uncaught InternalError: I2C Write Error 33281
   atUncaught InternalError: I2C Write Error 33281
   at line 1 col 18
  a.writeTo(c,[d,g])
                 line 1 col 18
  a.writeTo(c,[d,g])
                   ^
  in function "write" called from line 1 col 4   ^
  

  When i try to use software I2C, it kinda works, but only the first measurement and the humidity is wrong.

  var BME = require("BME280");
  var i2c = new I2C();
  i2c.setup({scl:A5,sda:A4});
  var bme = BME.connect(i2c, { addr: 0x76 });
  console.log(bme.getData()); // logs { "temp": 24.00835012295, "pressure": 961.35353842504, "humidity": 84.1865234375 }
  
  setInterval(function() {
    console.log(bme.getData()); // logs { "temp": -143.48718913660, "pressure": 1126.77476317288, "humidity": 0 }
  }, 1000);

  Thing is, it does work on my Espruino Pico using this code:

  var BME = require("BME280");
  I2C1.setup({scl:B8,sda:B9});
  var bme = BME.connect(I2C1, { addr: 0x76 });
  console.log(bme.getData());
  

  This logs the correct humidity, works with hardware I2C and continues to work (in a setInterval for example).

  I don't know what to do at this point. Is I2C just broken on (my) pixl.js?

• brand new puck.js v2 – already bricked?

  i feel kinda stupid. the battery simply was empty.

  is the "flashing red to indicate low battery" a feature? because i did not see it documented anywhere

  Hi,

  i just got my new puckjs v2. Everything was working when i got it.

  Here is how i apparently bricked it:

  1. flashed https://www.espruino.com/binaries/espruino_2v06_puckjs.zip (even tho it already had that version. realized that later)
     
  2. the next day: bluetooth connection would fail with the puck blinking red
     
  3. tried to hard reset it, but I'm always only getting red blinking leds
     
     

  did i already brick it – anything else i can try?

  • i measured the battery, its 2.8V
    
  • can not find the puck on bluetooth anymore
    
  • it's only blinking red sometimes. and I can't get it to reproduce
    
    

  edit: previously could not get any led to light up. it now blinks red – content edited to reflect that
