I think I have found another use case were using the actual active and connect API will lead to unstable behavior. Look at this thread http://forum.micropython.org/viewtopic.php?f=16&t=2697 I think we definitely need a method that does not only write into flash but it does not retry to reconnect to ...

I understand that you "really" want ESPlorer to work with micropython. You should probably contact the author of the program https://esp8266.ru/esplorer/ As far as I can tell it is NOT working properly with micropython. To me is a deprecated tool that should not be considered for micropython develop...

I think I have found a major source of instability in my applications. The problem is related to WiFi reconnections. This is the test that leads to the problem: 1. Plug USB cable to the esp device and see the output from console (e.g. using picocom) 2. Get the device connected to your AP (suppose si...

In the context of this thread about saving to flash, the second variable would specifically invoke the behaviour of NOT saving to flash, like this: noflash=1 WLAN.active(TRUE,noflash) WLAN.connect(wifi,passwd,noflash) I had the same point: two more API or an optional parameter is almost the same st...

Hello @ernitron I added also 4.7KOhm resistor and the result with D5 and D6 is a buzz at startup. Did you put the 4.7k Resistor in series or parallel to the piezo? You should put it parallel, to reduce the inital voltage at the output to about 0.4V. And obviously you should then configure that port...

Dear Deshipu I was pretty sure somebody would have rised this topic, and I was ready to bet it would be you ;) Indeed, it is time for a balance of MicroPython status especially with the forthcoming generations of IoT micro devices. I am one of the guys coming from NodeMCU/LUA and Arduino development...

Robert thank you very much (also to host me in your thread but maybe I can move the whole thing if it gets too fat here ;) However I am a bit puzzled. I use a piezo buzzer (this one from https://wholesaler.alibaba.com/product-detail/SFM-27-W-12v-buzzer-alarm_2004283581.html I use exactly the SFM-27-...

Thank you Robert, very interesting. I don't know if I may use your thread to post some more information about WeMos D1 mini and pose some questions. If not I can change topic and move to a more specific one. I measured the PIN Voltages just after a POWER UP and I found some interesting results. I me...

Dear @pfalcon (Paul if I can), thanks you for your replies. By the way I think 1.8.6 implementation is a big step ahead with webrepl usability. Regarding clear passwords I have one more use case... just make a laugh, it's a funny story :D Recently I gave away a couple of WeMos devices with my microp...

It looks like a bad flash / corrupted file system. Check again all the toolchain. The xtensa compiler, the esp_sdk, the esptool.py. It can be also a corrupted flash but most likely is the software toolchain. Some people had some result shifting from Windows to Ubuntu or Mac. This is kinda magic I ca...
