  Hi I tried the example at https://www.espruino.com/hmac but on my Ruuvi hashlib is not found. Any idea why? Thanks, Jens

  Ok, after a power cycle the flash worked as expected again. Unfortunately only for a very short time (after 3-5 more flash write attempts it breaks again).

  Hope this can be fixed soon.
  Thanks

  Great! I have missed that. Works like a charm now.

  Thanks a lot

  Hi All,

  I have the following code that does not do what I want:

  ...
  NRF.setServices({
    0x180A : { // Device information
      0x2A25 : { // Serial Number
        readable: true,
        value : [getSerial() + '#' + count_str]
    }}
  });
  ...
  

  The variable count_str is a counter as string that gets incremented every time I connect in a "NRF.on('connect', function()". I can see that the counter string increments correctly (puck console), but when I check the services and characteristics that the Puck advertises via Android, I see only the initial value of the counter string (#00000 - Serial Number) and not the updated one.
  I am not aware if this is maybe a caching problem of Android? Do I have to do anything else to receive the updated counter string?

  Thanks

  Ok, I tried the code below:

  // Tested on Puck.js
  var f = new (require("FlashEEPROM"))();
  f.erase();
  console.log(f);
  f.write(0, 'Hello Flash.');
  console.log(E.toString(f.read(0)));
  

  and got:

  Am I doing something stupidly wrong or do I have a faulty puck?

  Thanks again
