  Great! My issue above finally solved with new build.

  @Gordon: Got it, for your explanation :

  I think what is happening in this case is IRQs are being used to send the data via software serial, but they're also being used to receive as well - so you're basically guaranteed that when a pin changes state Espruino will be at least a little busy, which will mess up the timings. At lower baud rates you might be fine though.

  Thanks to @Robin , for the insight and opening relation to other links/threads.

  Thanks, Robin.
  Yes, I always prioritize some reliable hardware serial ports provided. Just my attention was momentarily attracted by good news in the paragraph:

  https://www.espruino.com/USART
  As of Espruino v2.00 you can set up 'software serial' using code like:

  Some months , not coding on Espruino and I started trying "software serial" code on Pico with pin A6 and A5 connected with wire, such:

  var s = new Serial();
  s.setup(9600,{rx:A6, tx:A5});
  s.on('data', function (data) { print("<SoftSerial>"+data); });
  s.print("Hello");
  

  But the result :

  Always only last character is correctly detected on event data received, for every send package of characters.
  Is there a mistake in my code usage ?
  Thanks.

• issues when re-flashing pico to latest espruino after running micropython on it.

  Hi,
  I get same problem.
  But I am confused to find which one a correct file with a bootloader easily.
  Does pico (or espruino wifi) firmware inside zip file with link : http://www.espruino.com/files/espruino_2v00.zip actually contain a bootloader ?

  Thanks.

  Try with :

  s = require("Storage");
  s.getFree();

  It should work !

  Thanks Gordon.
  Anyway,I am still curious and I don't check out yet , whether there is any significant declining in available memory usage in 2v00 compared to previous version

  Hi !
  After upgrading firmware from 1v99 to 2v00 successfully on Espruino Pico,
  Each time upload whatever code with "Save on Send" Mode,and "Direct to Flash".
  The red color warning comes up such this :

  "You have pre-1v96 fimware. Upload size is limited by available Ram".

  It never happened in 1v99.
  Is it normal or something wrong in uploading process? What should I do.
  Thank you.
