Problems with NodeMCU V3

#1 Post by comtel » 20 Jun 2018, 15:39

Hello,
I was able to flash the NodeMCU V3 with the ESP firmware
Successfully completed!

Unfortunately, the NodeMCU V3 does not start as an AccessPoint

I am new to the topic
what am I doing wrong?

Hardware:
"NodeMCU V3 ESP8266 ESP-12 E Lua CH340 WiFI WLan IoT 32 Bit microUSB Arduino"
(From a large online shop) ;)

maybe someone has an idea
sorry for my bad english :oops:

unfortunately no success
No access point

DONE!
(You may disconnect the unit if you want.)
Flashing done (76.5s).
Start flashing on COM5 (This might take a minute or two...)

Open serial monitor, COM port is not avaiable
for flashing as long as this connection is open.

I have no connection active :?:

Sounds like you try to open it while the flashing is still taking place. Please try it again.

Still, are you sure nothing is using the com port when you click that button? As in, restart your computer, start the Flasher and click on that button.

I found the problem!

I followed instructions as a beginner.
There was a USB TTL adapter recommended for flashing.

Flashing also worked. However, it did not work then.

Now directly connected via USB, everything works as described.

Thank you for your help!
