You are in the right track. You don't need Aes or crypto.

What device do you intend the file system to be on? Are you going to wire up an sd card?

The file system has been ported on the esp32 to use flash memory - flashfs
If you have enough flash memory this could be an option. How big are your files?

If you are using two sensors on the same pin - you only need one resistor - you don't want it on both.

Is vdd 3.3v? If so a 3.3k resistor might be better.

If it more reliable when you only connect one sensor at a time?

Also - comment out the reset - that might be causing an issue before the search.

As we have moved the v3.1x of the firmware - the firmware size has grown.

The default is to have the espruino built with debug, so if you do this it will make a firware that will fit:

make clean && BOARD=ESP32 RELEASE=1 make

Sorry, the esp8266 port does not have enough free memory for tls.

No - this was not a known issue.
The change in the versions that work to it not working are changing the ide from esp-ide 2.x to 3.x
There is a recent release of 3.1.3 which I'm currently testing - this might sort the random rebooting.

I'm not sure if there will need to be changes to the serial driver to get the settings to work - @JumJum - any ideas?

A quick google shows

https://electronics.stackexchange.com/questions/385879/esp32-i2c-read-command-produces-no-clock-signal

I think this is related to clock steching by the slave which might not be implemented in the hardware version used on the esp32.

Can you try the software implementation?

Can't see anything here. Is it in your copy?

@SergeP
Where did you do the pull request - cant see it in espruino github?

Sorry - ping was only recently added to the esp32 build - it might not be on a release build yet - which firmware are you on the esp32?

You want to look at wifi.ping to an address on the Internet - depending on the response you can work out if you have an Internet connection

@tve - welcome back!

Hi,

Looking at your code above - the headers is not doing what you think it is... - the parameters need to be part of the path.

path: '/eb/belt/washington/tolls.json?orderBy=%22$key%22&limitToLast=1',

Without this you get 600k of data back and this is too much!

However - this is not the issue.

It looks like since the esp-idf version of the mBed TLS was added that https is no longer working... This simple case fails:

var http = require("http");
http.get("https://www.google.com", function(res) {
  res.on('data', function(data) {
    console.log(data);
  });
});

Added a new issue:

Please post your code, a simple example would be best.

@Gordon

Will calling jswrap_interactive_setTime adjust the timeout values?

You are using a special character > 127 and that does not look like these are supported.

So we need to change it to jshSetSystemTime(), I think

I don't understand why this would make a difference? Do you think this would update existing intervals?

Isn't this because when the espruino starts its at time 0 - 1970 and then you are setting the time - so the intervals immediately expire?

What if you set the time first and then set the intervals?

@Gordon - any ideas?

The issue is that the library esp provides takes a buffer - and the espruino calls send one byte at a time - so it's taking a buffer, and sending it a single byte - so it's really inefficient.

The esp32 build supports https.

That dns name does not resolve:

https://firebaseio.com/ - in the browser it for sure if you prefix with www.

It looks like it's next trying to do some login/authentication - they might be quite tricky...

The esp32 build has a flash file system using 1mb of the 4mb inbuilt flash.

Support for external sd card has not be implemented. It could be supported however the flashfs implementation would need to be disabled.

Further to above - what mode are you saving in? It will also save the setTimeouts, and your code could re add them causing chaos!

Do a reset(1); to clear all the code and possible use the ide save in send feature. This saves to flash and restarts the code fresh each time.

Won’t this need to be done interactively?
E.g start the pairing and then enter the pin - probably via the console directly into a (new) function call?
