Thanks for your help

I tested :
import urandom
nb=urandom.randint(0,9)
And I have the same error message

Hi,
I have 2 ESP8266 communicate with ESP-NOW. I need to generate a random number on one side and send it to the other ESP.
When I write:
import random
nb=random.randint(0.9)
I have the error message: AttributeError: 'module' object has no attribute 'randint'
Where is my mistake?
Thanks.

Hi,
Thank you for your answers.
I'll see if the RMT module can help me move forward.
On the other hand if someone has an idea to build a routine equivalent to pycom.pulses_get (), I am interested.

Hi,
thank you for your reply. The Github https://github.com/micropython/micropyt ... rivers/dht matches my request but it's written in C. I'm looking for something like https://github.com/garyns/ pigpio-dht / blob / master / lib / pigpio_dht / dhtxx.py, adapted to ESP32.

Hi,
Yes I know there is a pilot but what I want is to understand how it works. Is there a DHT.py for ESP?
Regards.

Hi, I am using Micropython on an ESP32 and want to understand how add-on libraries work. I started with the HD44780 library, and now I'm trying the DHT11 / 22 library. I found several but they are either for Raspberry, or for Cpython, or others but not for ESP. In short, I can't do the conversion wi...

Thank you for this information.
I will read them and try to assimilate them.

Thank you for your reply. I have already seen this solution, but during these 10s the ESP is blocked, and that whatever the delay.
If I understand correctly, the WifiEventHandler works like interrupts, which means non-blocking.
Is it correct?

Hi, I don't speak perfect English and I use the Google translator ;) , sorry if the syntax is not perfect. I had fun with an Arduino with C ++ and now I want to use an ESP32 in Micropython, which allows Wifi connections. Most tutorials use a blocking loop to connect like: in C: While (WIFI.Status ()...
