Wifi Connection

[peter67n]

Hello,
I have question, where I have not found an answer yet.

I get the bin file running on an ESP8266 Nodemcu.
On a Wemos D1 ESP8266 I can only see the AP and are able to connect. After setting the network ssid and password, it will not connect. Only AP is available.
On a Wemos D1 ESP32, nothing is working at all. No AP is coming up.

Would could be the issue, that Wemos D1's are not running?

Hi. Let's exchange a little more info:

• how exactly did you flash? Did you follow the quick start and compile settings at https://github.com/Aircoookie/WLED/wiki ?
• what exact bin are you using? The 0.9.1. from https://github.com/Aircoookie/WLED/releases ? The "WLED_0.9.1_ESP8266.bin" for the D1 8266 and the "WLED_0.9.1_ESP32.bin" for the 32?
• did you try just running the controllers powered via USB without any LEDs attached and see whether you can connect and config them etc?
• how many LEDs are you trying to use?
• what type of LEDs?
• what's your power supply?
• can you share your hardware setup including power supply and all wiring, so a diagram or picture where we can see how you wired up everything

Let me try to provide answers.
Yes I was reading the Wiki and the christmas tree build.
The bin files you are mentioning are exactly the files, I was trying. To flash the ESP's I'm using esptool.py as I do with other software too.
I have no LED's connected at this time, just the micro to see, if the wifi connection is working and that I have a chance to move further.
I hope that the software is not really waiting for a connected LED in order to connect to the home network. At least this is my assumption. The nodemcu did everything I have expected at this time.
My problem is, that I do not understand, why the Wemos D1 parts are not connecting.
All boards are connected via USB Cable to a MAC for this test. Later I have planned to use a bigger power supply, depending on the amount of LED's.
Any idea?

I myself am using Wemos D1 8266's next to NodeMCU's, so it is not a generic "Wemos D1's don't work".

It's interesting that the Wemos 8266 comes up with it's own AP but won't connect to your Wifi. Only things i can think of for that:

• you're not doing anything on the AP/router/network that would prevent a new device to receive an IP (like mac filtering etc)?
• you've tested it while being close to the AP?
• did you try both using DHCP and a fixed IP?
• you're sure ssid and pwd are set correctly?

Not sure whether trying to have it connect to a device in mobile hotspot mode would be a useful test, but maybe try if you can?

It we don't learn anything new from these questions/answers, i hope someone else or one of the devs steps in.

Hi, sorry you are having issues getting it to work :)

For the Wemos D1, please try @raoulteeuwen 's excellent advice first.

For the ESP32, flashing is a bit trickier. Please try this: #517 (comment)
and let me know if it helps!

It's working :-)
Maybe somebody else is having the same problem, so let me note how it was solved.

Wemos D1 ESP8266:
Also the parts were newly bought, I had to erase the flash before the bin file was flashed. Then it worked.
Flash File: WLED_0.9.1_ESP8266.bin

Wemos D1 ESP32:
The issue #517 helped me in solving it.
Erased the flash once again. Flashed the mentioned boot loader at 0x00000 and after that the bin file at 0x10000.
Bootloader File: esp32_bootloader.bin
App File: WLED_0.9.1_ESP32.bin

In both cases it connected via dhcp to my router.
Many thanks for the help

Hi @peter67n,

nice to hear that your WLED is working now - could you please close the issue, if it is resolved ?
