MicroPython - ESP32 - Is is possible to update files?

[guyd]

Hi,

I'm using ESP32 to activate a scheduled GPIO on and off ( relay ).
Time schedule is defined in a file saved on ESP32.

Is it possible to change this text file while ESP32 is not connected to PC using cable (ESP32 is already installed on remote location ) ?

If WiFI is activated, it may be possible. But that requires some agent being active on that device, like WebRepl.

Hi,
Yes, Wifi is activated, but WEBRepl is available for ESP32 ?

Do u have a ftp server running on the ESP32??

[guyd]

Not one that I know of

You could use the loboris fork for esp32 which has a ftp-server built-in which just has to be enabled. Then you can easily modify that file.

A different approach would be to get the value you have in the file by mqtt subscription.

Thank you for your answer.

1) I look for loboris - it seems interesting. Does it mean I'll have to flash a new bin of Micropython ? BTW - it is possible to run telnet without loboris ?

2) This is another way to look at it ")

1) yes, you can download the prebuilt firmware on his repository and flash it.
1b) I have not heard of telnet outside of loboris fork
