ESP32 network activation resets the board

[pccminister]

Hi

I am a noob in micropython and my background is in PLC and Industrial automation.
I`ve found some interesting stuff in micropython for my projects eg. MQTT.

I tried to connect to my Wifi with ESP-WROOM-32 and when I try to activate the wlan according to reference in micropython.org I get this:



when I type wlan.active(True) the board resets itself?!!!

Should I buy a new one?

That could be a power supply issue. Try another USB port, capable of delivering robust power, like an USB3 port, and use a good USB cable.

yup! that was the problem.
thank u
note to self: dont use self-made usb cables for important projects

This could almost become part of a FAQ. There are quite a few questions in the forum on the same issue (amonst them one of mine )

Hey,
The thing is, some electrical motors like Siemens (https://eltra-trade.com/catalog/siemens-motors) include PLC programming, along with SCADA, DCS, Instrumentation, etc..
Looking at the other end, PLC programming is used for Industrial Automation, in addition to some other fields.

Funny thing. My bg is industrial automation to Glad that you solved your problem!

thank you for the support

PLCs have to work with IoT soon there will be cheap PLCs with the ability to work with and alongside IoT.

I was so lucky to know about micropython so soon. C was making me pull out my hair!!!
