ESP8266 snoozes on Wifi
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...

Re: ADC read frequency
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?

Re: MicroPython can't boot up
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...

Re: Robust network protocol - looking for inspiration
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.

Re: Windows development enviroment/IDE?
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.
greetings Herbert
