Hello....
I have MakePython ESP32 Development Kit with Thonny...
I have made a program witch send data (temperature and humidity) to the web(ThingSpeek) it run well , the BOARD CONNECTED to my PC
The I download my program as main.py into the ESP32 board
I reset the board.....now the program do not word , some files must be not present on my board ?
A part of the program run (temperature and humidity on OLED display ) , but nothing is send to web
Searching to solve the problem
I try a elementary program you can see below named main.py I have downloaded in the ESP32 board
Obviously this program work well and I receive the message 'a very difficult program' when I execute the program with Thonny....but the board alone connected to Pc do not work ?
main.py #my program on ESP32
#****************************************************
print('a very difficult program') #only that !!!!
#****************************************************
Now
*my board always connected to my PC
*Thonny IDE always open
*I reset the board with the reset button
I don't receive the message ? How to do ?
Thanks very much for all suggestions
Best regards
Send data from ESP32 to Thonny......how to do ?
Re: Send data from ESP32 to Thonny......how to do ?
Which shell program are you running on the PC? How have you got the PC setup to see the >>> REPL prompt?

Re: Send data from ESP32 to Thonny......how to do ?
Thank you very much for your answer !
I have no problem with the REPL on THONNY I know how to use it.
(perhaps...)
To recap....
main.py program: print("hello word") downloaded in the board
I reset the board
I would like to see in the REPL window 'hello word' but nothing
With ARDUINO it was possible ( if I remember me ?)
In fact I was searching a most important problem describe earlier. My program who send data to ThingSpeak ,it work very well.....connected to PC but not alone !!! (see it below)
There was two problems
* I did not receive connection information ( print(station.ifconfig()))
* The ESP32 did not work alone
I have found a part of solution I have reset my PC and now my program work well alone, and if I open THONNY then reset my board I receive a message from my board !!!!!!!!! but !!!!!!
(('192.168.1.33', '255.255.255.0', '192.168.1.254', '192.168.1.254'))
if I do the same thing with this extremely difficult program: print("hello word") as main.py of course downloaded in the board I don't receive any message ,doing the same action above !!!!!!!!!!!!!!!!!!
I appreciate very much your answer it allows to advance...
