Cannot run program "/usr/bin/python" (in directory "/home/jack/Documents/sketchbook/nodeMCU_HotWaterCat5/build"): error=2, No such file or directory I can use the plugin installer and see I have a python file in the 'tools' folder..with a solid star.. dont know where to go from here..

Python on Linux / OS X relies on a system installed version of python. I'd expect most systems to already have one, but maybe your system doesn't. Try installing python? You will also need to install pyserial as well.

THANKYOU!!

FYI NOTE.. after the initial upload, which is successful, then next uploads fail due to baud rate.. I use 9600 and apparently that value is retained, instead of the correct baud rate for programming..115200.. I changed baud rate to 115200 and uploads work again.. not sure if this is an error of just how things must be.. thanks again, nice to have this project working..

matt:

The upload baud rate should be set at upload time through the ESP8266's autobaud method - that is, enter programming mode, then send UUUUUUUUUUUUUUUUUUUUUUUU, which sets the baud rate to whatever it need to be. All that is done by esptool.py, and nothing to do with UECIDE. It could be that something is happening to the DTR/RTS signals that's preventing it going into programming mode until you do something to change the baud rate which then resets it. Try running:

stty -F /dev/ttyUSB0 hupcl

after uploading and before a new upload, without changing the baud rate, to see if that makes it work. If it does it'll prove it's a DTR/RTS problem.

I tried stty -F /dev/ttyUSB0 hupcl but I get-- ack@jack-ThinkPad-T410c:~$ stty -F /dev/ttyUSB0 hupcl stty: /dev/ttyUSB0: Device or resource busy

USB0 is the correct one for the board..

matt:

Something's locking the port. No idea what. You could try the good old uninstall of modemmanager, see if that helps.

solarJack:

Looks like if I just close the serial monitor in uecide, then upload, all is good.. this time I tried switching back to 115200 and it still gave the same baud error from python.. I will just close serial monitor before I upload.. not so bad..

matt:

Ah, the serial monitor. Yes, you must close that.

Running this server costs money. This server not only hosts this website, but is also the main build platform for creating the download files for UECIDE. Just a couple of pounds (or Dollars, Yen, Mongolian tögrög... we're not fussy) can help to offset the costs.

Alternatively, if you want to be more personal, you could buy me something on Amazon. I have a small wish-list of low-cost items that I'd quite like to receive. Make it a surprise.
