Re: [Help needed] Sonoff Si7402
Finally manages to compile micropython again. That's probably 4 years since last. Compiler setup, was not easy, but it succeeded in the end. So I changed a line in "micropython/drivers/dht/dth.c" namely line 55 to: "mp_hal_delay_us_fast (493); // mp_hal_delay_ms (18);" I have not tried with other ti...

Re: [Help needed] Sonoff Si7402
An appetizer.
I found a program in WIKI under: DHT22 temperature and humidity sensor
https://github.com/kurik/uPython-DHT22
I only use data_pin which is Y2 and has changed line 73:
while micros.counter () <493: # 25000:
Hope this is something you can use.

Re: [Help needed] Sonoff Si7402
Hi, is this a Turkish error, or is it sonoff si7021.
I have a couple of pieces that work just fine on my Propeller.
I have found that the starting pulse should be approx. 520 microseconds.
And I have the measuring pulses of 48 microseconds.
Hope this can help you further.

Re: "SUB client" of umqtt simple.py crashes on EVERY message sent by another simple.py "PUB client"
You must have different client id on every esp for it to work.
Chance "umqtt_client" to somewhat different on one of your ESP.
Code: Select all
c = MQTTClient("umqtt_client", server) on your PUB
c = MQTTClient("umqtt_client", server) on your SUB

Re: keep wifi and umqttsimple "alive"? (beginner question)
Maybe you can use something from my program? I use a Sonoff to turn on some light at sunset. They get the commando from a Node Red server running on a Raspberry pi. Every time its reset, the counter gets reset also. IF the counter is zero, Node Red send the command again. from machine import Pin, PW...

It may depend from the terminal emulator. Picocom switches by default the modem control lined in a way that is seen by the esressif kind if bott loader enabling as reset. You can disable that with calling options I use GtkTerm to communicate with. The same is true when I supply the circuits from a ...

Re: main.py does not appear to working after boot
I have some ESP32 PICO and they always have a reset after power on, before I can communicate with them.
But my NODEMCU ESP8266 has no problems.

utime.ticks_diff() between pycom and upython
In upython, utime.ticks_diff (new, old) gives positive results. In pycom, utime.ticks_diff (old, new) gives positive results. Old and new have been switched, I wonder why, there is no change in the underlying code. It must be somewhere, between the call and the underlying code. ps. I prefer the pyco...
