Hi I do use ESP8266 with WIFI for a long time. We turn on lights open garage doors and so on. since 4-5 months now the device reacts very slow (15-60 secounds) delay for MQTT, which was never before. My suspicion is that the Google WIFI mash system is creating that problem, as I tried with another W...

Hi, your code could be around 3 times faster, but still not 0.5 to 1Mhz i mport utime import machine adc=machine.ADC(26) time_start = utime.time_ns() for i in range(100000): val=adc.read_u16() time_stop = utime.time_ns() elapsed_time = time_stop-time_start time_s = elapsed_time /1000000000.00 print(...

Maybe you want try ctrl-d in terminal/REPL, instead of unplug and replug the USB?

Hi,

Adafruit ampy works the same way is it works with the esps

Good luck

How did you invoke esptool? In the following you may need to change the port to suit your system. First erase the flash: esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flash Then try the following: esptool.py --chip esp32 --port /dev/ttyUSB0 write_flash -z 0x1000 esp32-20170907-v1.9.2-269-g5311c...

I also use MQTT finally I got it to operate very error tolerant.

Most of the examples ignore that the Broker could crash or even WIFI.
But after sorting that out with the code I think it's the best solution.

Hi, this is not quite the answer…

I'm using PyCharm Community and WinScp if FTP is available and Webrepl if not.
even there is an addIn for MicroPython I don't use it.

It's productive for me.
