I am a little bit confused.petermeigs wrote: ↑Sat Sep 29, 2018 5:03 pm7. Here is uploader.lua. This will let you telnet to your esp8266 which is much cleaner that the serial port. You will have had to establish your wifi connection before this
Is it true that your FTDI USB to TTL UART serial cable is noisy therefore your LUA script uploading using ESPlorer is not reliable?
As I mentioned earlier, one TaoBao shop said that many people have noisy USB to TTL cable and one solution is to buy their cable with a big 1000uF cap on board.
I actually bought their cable but not using it, because it is using the 8 pin connector which is standard for ESP01 board, but not for my ESP12 board.
For my ESP12 board, my PL230x USB to TTL cable seems OK, but I am not too sure, because I am playing with very short LUA programs.
Actually most of the time I am using a plain USB cable, because my ESP12 board has CH340 USB to TTL converter chip on board. I guess the on board converter is very clean and does not have noticeable noise problem.
I don't understand what you are saying below. Are you using telnet/ftp instead of using ftdi cable to upload the script? Or are you testing WiFi uploading/downloading your 24VDC pump status data Rpi to/from ESP8266?

Earlier, I have posted a script to let you telnet to the esp and that will help a lot but does not solve the upload issue.
If you find a proper ftp to be able to upload (and download) please post it here. That would be super useful.
