There is no "nodemcu" buffer

[pastukhov]

Serial port widget suggest to choose "nodemcu" buffer, but there is no such thing.

I am on ubuntu 15.10 x64 with chrome 41.0.2272.89.

You need to be running version 1.88 of Serial Port JSON Server. What version are you running? You cut it off in the screenshot.

I'm using http://chilipeppr.com/downloads/v1.86/serial-port-json-server-1.86_linux_amd64.tar.gz Is there any precompiled 1.88?

So sorry, it wasn't fully published when I posted on the nodemcu forum. I just published it.

Interesting. The moment you open the port it closes on you. I have seen this before on Linux. For some reason the EOF lingers from a previous open of the port and when it gets sent in to SPJS it chokes thinking the port is closed. As weird as a possible solution might be, what if you unplug your USB then plug back in to massively reset the port and then try?
