If you are on 64 bit Windows the best bet is to install WSL. Windows subsystem for Linux. It's in the Windows shop app.

This gives you an Ubuntu shell window without needing to install Linux in a virtual machine.

Once you are in the shell - do the apt-get to install the build tools as per the Linux instructions. Then you can just a make and build the Linux version of espruino, which you can then run with ./esprunio --telnet

In your ide, you can then connect to localhost:2323 to connect to this install running in Linux on top of Windows.

Try disabling BLE. I noticed it ran hotter when this was added to the firmware

@jumjum implemented this, the number of jsvars is determined at startup by looking at the available heap.

Since the pins will be connected to two devices - you might get unwanted results. I2c usually has a pull up so that might also cause issues with serial.

Why can you just use another 2 pins an keep them separate?

Use the programme putty.

Or use the web ide.

Why do you want to write directly to the com port?

What about pin mode opendrain with a setting of 1? That should be open state.

That is for offical espruino boards - not esp32.

What do you want to update with ota? A. the firware the espruino version, or b. the currenly running software? If it's b, then this is something you can do with what is already available. You could read a new programme update from a hosted page and save to the flashfs file system. You could then bootstrap this in to be the active code - save to eepprom, and reboot.

It's not been done. The partition table has been set up so that we have room for two firmware but the ota library has not been done.

Espruino does not have a jvm. It is not java - it's JavaScript and it's interpreted rather than complied.

The esp32 implements the fs filesystem using flash - that has 1mb of flash set aside - use that to store you files. If you look at the docs you should be able to find out how to initialise the space, or search the forums.

Yes. We updated to the latest esp-idf v3.1 and it seems to use more memory. We've not been able to establish what is taking up more space - I suspect buffers used for wifi and ble. @JumJum

I think you would have to compile into the firmware. The is graphics for output - im not aware of any input device that you could use as an example.

What does the nfc device do? Isn't that already built into the module - or is it not ble?

The watch with esprunio on it has me interested.

The default espruino build for this model only has 1 spi defined:

https://github.com/espruino/Espruino/blo­b/master/boards/MDBT42Q.py#L60

Support could be added for SP2 and SP3 in hardware.

Pins are checked to see if they can be used:

It's so that B is not sent until A is done, it waits until the event is complete before adding a new event.

I can confirm that this is working now.

Thanks for updating!

I've manager to reproduce one of these issues using a current build on linux.

vue native sockets in chrome browser -> Backend Espruino WS server.

If protocol is specified, then all is well:

const ws = new WebSocket('ws://192.168.1.203:8000', 'protocolOne');

However, if this is defaulted, ws.js on the espruino sends as a header:

Sec-WebSocket-Protocol: undefined

this test seems to be failing:
https://github.com/espruino/EspruinoDocs­/blob/master/modules/ws.js#L196-L197

if (this.protocol)
    socketHeader.push("Sec-WebSocket-Protoco­l: "+this.protocol);

in the constructor we have:
https://github.com/espruino/EspruinoDocs­/blob/master/modules/ws.js#L76-L86
this.protocol = options.protocol;

So it seems this is setting this.protocol=undefined.

What is the cleanest way to fix?

if ( typeof(this.protocol) != 'undefined' )

Please Post your connect to wifi code

Sure, what's a 'PR'? :-)

You're thinking of using Travis to do the builds?
I think he means the provision script that uses espruinobuildtools
