Thanks Gordon, I'll try that.

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

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:

f.write(0, 'Hello Flash.');
                         ^

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

Thanks again

Indeed I did. Thanks for the info.

Hi @allObjects, Yep, I used the very simple example from @MaBe and that is what I get instead of his output:

|   __|_ -| . |  _| | | |   | . |

A puck.js (received about 1-2 weeks ago) with the 1v90 firmware.

Ok, never mind. Removing and inserting the battery solved it.
Thanks.

Hmmmm I did a firmware (1v90) upgrade too and tried the osx cli with "espruino --list" for sure 20 times but all I get is "PORTS: /dev/cu.Bluetooth-Incoming-Port" too.

Any other ideas?
Thanks
Jens

@allObjects, Hi I tried all that you suggested and still have the timeout problem (in the web console pane as well as a program). Any other ideas? Funny seems that when I write a string with a specific length and read it afterwards I get a length number ox 0xff - so the length seemed to be stored somehow.

Thanks
Jens

Hi,

Did anyone of you experience the same error?

Thanks

Thanks, that works perfect.

Thanks a lot. Will try that.

Hi,

I tried to find a way to count the number of connections made via BLE. Is there an easy way to accomplish that?

Thanks
Jens
