Getting the ESP8266 to reboot micropython itself... possible?

Hi All OK, so this may already be possible, apologies I am fairly new to the world of python and micropython. So, I have successfully flashed micropython to several of my ESP8266 boards and have one set up and running with a BME280 environment sensor connected, uploading data to Adafruit.io. However...

Re: Wanting to send data with different intervals

time.ticks_ms is a method only available in micropython, not on your pi. on your pi you can use time.time() which returns seconds so you have to replace the 3000ms in my example with 3s. Think I figured it out... don't need the last sleep line. import time temp = 20 press = 1021 last_task1=time.tim...

time.ticks_ms is a method only available in micropython, not on your pi. on your pi you can use time.time() which returns seconds so you have to replace the 3000ms in my example with 3s.

Re: Wanting to send data with different intervals

You might be right. By the way, don't disconnect from mqtt if you don't have a good reason to do so. I tried this code in my test set up on the Pi... and get an error Kevin... any advice please? Traceback (most recent call last): File "/home/pi/Documents/john_count.py", line 7, in <module> last_tas...

Re: Wanting to send data with different intervals

You might be right. You can do something like this: last_task1=time.ticks_ms() last_task2=time.ticks_ms() while True: if time.ticks_ms()-last_task1>=3000: # publish data of task1 every 3 seconds c.publish(...) if time.ticks_ms()-last_task2>=8000: # publish data of task2 every 8 seconds c.publish(.....

Re: Wanting to send data with different intervals

Thanks Kevin, this is certainly something I will add to my 'need to learn' list, but might be a tad overkill for my needs just now. I have managed to write some test code on the Pi using IDLE that seems to do the trick; a little tidying up and I think I can add this to my ESP32 MicroPython code. imp...

Wanting to send data with different intervals

So I have the following MicroPython code in my script, running on an ESP32, which uploads the data from a BME environment sensor to my Adafruit feed once a minute, however, for the 'pres' variable, I don't need to send that data up to my feed anywhere near as often. I'm very new to Python, and am wo...
