Any different option/setting to choose between ESP12E and NodeMcu

no need for special tools Marvin.
just open cmd Windows and type arp -a
you will see all the devices with IP address and Mac.

Sure! Windows and Linux both have itā€™s own command line tools. But in Windows Iā€™m rarely using cmd, and the opposite while using Linux. Windows isā€¦ full of windowsā€¦ :wink:

I still think that Advanced IP scanner is better than ARP or Wireless Network Watcher.
It allows you to add friendly names and comments, and view services running on the various devices. But, in cases like yours itā€™s good to try anything that will help identify the issue.

Yes Pete
I also tried the advanced IP scanner, but when I disconnect my nodemcu, I always see it connected.:smile:

now i have flashed my nodeMCU as a wifi repeater, and I have been connected for 20 minutes, no disconnection!
same IP than before : 192.168.0.60
So, nodeMCU is not dead !
:thinking::thinking::rofl::rofl:

yes I will try now.
but why the other nodeMCU works like a charm ?

Here The core 2.4.3 does not show up ? Am i in the wrong place ?

71

there is no 2.4.3, try 2.4.2

Number dyslexia is a term sometimes used to describe learning issues with math. ā€¦ Kids with dyscalculia have trouble understanding math concepts, such as biggest vs. smallest. ā€¦ They also may struggle with reading word problems, reading number names, and spelling number names.

:rofl:

Still no luckā€¦ Still my ESP12E is not connecting.

to many issues with my code, I prefer to keep 2.5.0 beta3 :wink:
ā€˜IPAddress WiFiUDP::remoteIP() constā€™ marked override, but does not override

76

At last the ESP12E connects after 5 attempts on the reconnect 30sec tries !!
But when i operate the GPIO with the Blynk app it is very slow. And after 3 hrs or so it will go offline and comes back online after 20min .

Does reinstall of the Blynk local server will help ?
I also scanned with the advanced ip scanner as @PeteKnight said ! And i found the ip and mac is same.

Or should i buy a new router ? Or just hard reset it ?
Because the ESP is not connecting to Blynk cloud too !!

get a new nodemcu.
yesterday I tried 2 nodemcu , same core , same code.
the 1st connect within a second.
the 2 nd try to connect 10 times and reset.
after 2h it was connected, and this morning it try again to connect.
as I said, I uploaded a code to transform my nodemcu as a repeater mode , it runs like a charm without disconnect.
I will try it with virtuino or openhab to be sure there is something to do with blynk server.
tomorrow Iā€™ll order 2 nodemcu in China.
have a good day bro

I will buy new ESP12E and check if the problem is with the module or any other software oriented problem.
I will keep the result posted !!
Have a great weekendā€¦

Iā€™ll try a wemos mini D1 .
what do you think about that @PeteKnight ?
is it better than nodemcu?

I like them because theyā€™re smaller than the NodeMCU and you can choose how to solder the header pins on (or donā€™t bother with pins at all).
They also have the double and triple bases available, so you can make your own modular systems and easily swap things in and out, like this, which has a D1 Mini Pro, a Relay board and a Proto board:

Because theyā€™re plugged into sockets on the triple base you can pull components out and replace them easily.

I did a Pros and Cons comparison here:
