Device couldn't connect to network

Issues and Errors
1

I am trying to add a device on an Android, using the Blynk IOT app.

I have loaded the example Edgent ESP8266 code to my Wemos D1 Mini pro successfully.

When i try and connect to the device i am able to find and connect to the blynk network however on attempting to connect to the household wifi I always get
“You device couldn’t connect to the network”

I am at a complete loss as to why something so simple is just not working.

Any advice would be really appreciated

How many characters in your template ID ?

Okay, that’s not the problem then.
Very long template ID’s produce even linger SSIDs which exceed what the ESP8266 can handle when creating the access point for provisioning.

Are you running a 2.4 GHz WiFi network that you’re connecting your ESP to?

I notice that you haven’t un-commented a board type…

// Uncomment your board, or configure a custom board in Settings.h
//#define USE_SPARKFUN_BLYNK_BOARD
//#define USE_NODE_MCU_BOARD
//#define USE_WITTY_CLOUD_BOARD
//#define USE_WEMOS_D1_MINI

which means that the default board type will be used.
It probably also means that the LED and provisioning reset button probably aren’t working. Is this correct?

I have uncommented the board type. You were correct. The onboard LED was not flashing. It does now and yes I am running on 2.4 Ghz Wifi.

Even though the App doesn’t connect to the network. When i look at my router I can see an “Blynk-LED-Blink-360D5” wireless client as a connected item.

So lost as to why this is so hard :frowning:

Have you tried to erase the flash ?

I don’t understand that statement. I think maybe you’re doing something wrong.

Can you describe in detail the steps you are going through, and copy/paste the output from your serial monitor.

Pete.

On the Blynk website I have created the template. I am not attempting to add a device to that template on my phone via the app.

I have loaded the code in the pastebin above onto the wemos d1 mini pro sucessfully. When trying to add a device I get all the way until the configuring device section and then it fails. Here is the serial monitor output
