umqtt.simple is working great in every way except set_last_will(). I can't seem to get it to work. Below is a portion of my code. My two questions are: 1) How do I get set_last_will() to actually set a last-will on my MQTT broker (mosquitto). 2) How would I test this? Just unplug the esp8266 and wat...

THANK YOU Pythoncoder and Platforma!

The update to 1.8.6 fixed the issue.

To avoid this issue, you just need to set the correct flash size of your module when you flash the firmware. V1.8.6 is based on SDK 2.0.0 and flash size auto detection has been moved to esptool. Try this, before erase flash! esptool.py --port /dev/tty.SLAB_USBtoUART --baud 460800 write_flash --flas...

Yes, if erase too fast (less than 1 sec), it maybe not erase completely. It will take 2-3 sec normal, you may run erase command again.

Any recommendations on how to slow down the erasing process, to avoid errors?

I'm sorry I didn't include that as part of the description - but yes, I'm erasing the flash before hand. Is there a possibility it's not erasing completely?

I've been struggling to get 1.8.6 installed onto my nodemcu board. I downloaded 1.8.6, and ran this command: esptool.py --port /dev/tty.SLAB_USBtoUART --baud 460800 write_flash --flash_size=8m 0 esp8266-20161110-v1.8.6.bin It seems to flash the board correctly, but when I disconnect the board/reconn...

I haven't updated to 1.8.6 yet, but will give it a try today, and report back. Thanks!

...I would guess that it is some sort of timing issue with the data transfer. Can you speak more about this? I'm not sure where to start. The LED's go yellow on different codes as well, for example: import time, machine, neopixel number_of_leds = 60 np = neopixel.NeoPixel(machine.Pin(5), number_of_...

Here's my code: [code] import time, machine, neopixel, math number_of_leds = 60 np = neopixel.NeoPixel(machine.Pin(5), number_of_leds) def main(): while True: fade_in_out(red_val=256, green_val=256, blue_val=256) # white def fade_in_out(red_val, green_val, blue_val): for i in range(256): r = math.ce...

I'm confused about how to fire this up. I created 2 files, main.py, and networkconfig.py. Inside of main.py: import networkconfig networkconfig.start() Inside of networkconfig.py: The code contained in your repo. When restarted, my micropython access point appears, but I'm not sure what to do next. ...
