  @DrAzzy
  The initial problem you had should be largely sorted by this fix:

  https://github.com/espruino/Espruino/com­mit/5c9c7b5c561eda7408b2e5d8194f8127a6a5­d5f6

  It allows the port to be reused.

• Improve Neopixel Peformance?

  Looks to me line 19 there is still a console.log.

  Why don't you push the frame rates into an array and dump that at the end or in a timeout that happens say once a minute?

  Are you powering via usb? Try another lead and also a different port on the computer - or try powering directly from a 10w charger

  Following the calls from jswrap_net_kill it ends up here in the ESP32 case - so it has been implemented, so I think something else is going on.

  I have also observed this behaviour in the ESP8266 build.

• Memory out trouble

  ohh -0nce a second you are going to the internet to update the time?

  Instead do that a lot less frequently - say once an hour - and then set the internal clock to the time, and use the internal clock as your time reference.

  What is probably happening is a new call to get the time is made, when the last has not finished.

  What is the error output your are seeing?

  What is the output of process.env ?

  The will show the free jsvars after the load.

  If you use the save on send option in the ide settings, the code will be stored in flash rather than ram and you might not run out of space then.

  The issue is the the build is compiled with 10 sockets.
  When you reset, the sockets are not closed. Part of the reason for this, is one of the sockets was the telnet server socket - you would loose your connection to the board.

  If you saved the result of you your server connect as a global:

  var server=require("http").createServer(onPa­geRequest).listen(7348);

  Then before the reset - you could do server.close()

  This will shut down the connect and close the socket.

  By the way, are using using a telnet connection? It is so much faster than the com port connection.

  Oh - and your call to get the time - rather than have a page that returns the time - you can get the time out of the header..

• Application Structure with Modules

  in ESP32 • 1 week, 3 days

  

  There's a bug in the plugin that has been pushed to npm - lodash forEach - you have to edit that to get it to build which is a real pain.

  There has also been some changes to the espruino (confusing name - the npm code that talks to a connected board) that allows you to specify the port as "tcp://1.2.3.4" where 1.2.3.4 is your ip - this sends over tcp rather than serial ansis about a million times quicker.
