ESP8266 07 hosting a local server (wiring)

I have programmend and uploaded the program to host a local server on my ESP.
But for some reason the server it should be hosting isn't showing up in my wifi connections.
I'm pretty sure I'm not wiring my ESP corerctly, as of now I only have the VCC and GRND pin connected to the correct power supply. Are there any other pins that need to be connected?

Thank you :slight_smile:

What are the LED's doing ?
What name did you give your wifi? There's a bug in their code - spaces in the name or passwords break everything.

My wifi and password are generic names, no spaces, numbers or any weird characters.
The right LED is lighted up.
Something that might be the issue is that the ESP is in sleep mode perhaps? I'm not sure.
This is why I'm wondering if I need to wire anything else to 'wake it up'?

Is it a Dev board or just an ESP-07 ?
Either way, did you connect an antenna ? ESP-07 does not have an onboard antenna.
Have you pulled pin CH_PD (ENABLE) & RST up ? both need to be connected to VCC (through a 10K resistor as an option)
And i think GPIO15 needs to be pulled LOW, also through a 10K resistor.
From the picture, the ESP-07 does appear to have an internal LED, and chances are it is connected to GPIO1 (or GPIO2, but my bet is GPIO1, you can use the multimeter to confirm where the LED and the resistor are connected to, but the contact are rather small of course in SMT package) You can upload a program that blinks that LED.

I'm pretty sure that the ESP8266 07 has a build in antenna so that shouldn't be the problem.
But indeed I haven't connected the CH_PD and RST pins. Ill connect those to my power supply as well, can I just attach this to the same 3.3V power supply I'm using for the VCC in?
As well as the GPIO15. So with pull low you mean connect to ground?

Thanks for all the feedback already!!

Pretty sure it doesn't. The ESP-01 and ESP-12 do. A strand of solid copper will have to do for starters, but let's first get it powered up properly.


Yes again.
First, either find which pin the internal LED is connected to or connect a LED + resistor between VCC and one of the GPIO pins and blink that. (make sure it's active LOW, or make sure that it's OK to pull the GPIO LOW on startup)

Oke, so I have managed to program my ESP8266-07 through a arduino uno, and I now have a internet access point showing up. However there are still two problems I'm facing.

  1. I can't seem to connect to the AP, it just keeps saying connecting
  2. The AP only shows when I'm connected to my arduino uno.
    Is it possible to have a standalone esp8266-07 host a local server without an entire arduino?
    I have also purchased a ESP 13 just in case, since this for sure has an antenna
    I also have a couple of ATTINY's laying around incase you NEED some sort of arduino connected for it to be able to host a server.

I'm not buying a bigger pre made board with a ESP on it since this is just to big for my project.

Thanks for the help already man!

2 possible causes. Either something in the code you've uploaded, or something power related.
To determine which i will need more information. Please provide a circuit schematic. How are you powering the ESP ? they are know to be quite power hungry particularly during their WiFi connecting stage, where they have demands up to 300mA
Please post your sketch within </> code tags so we can see if there is anything not quite right in there.

Yes of course it is, again i need to see the code that you are running now.

So does an ESP-01 or an ESP-12. You can see the antenna as a bit of Zig-Zag trace on the PCB. An ESP-07 has a connection for an external antenna, which can be practical if you want to place the antenna a little away from the unit, and with which you can achieve significant more range.

Personally - I'd switch to ESP32 if I were you. ESP8266 gives no end of problems for me, but the ESP32 stuff is a joy to work with, including some useful "works out of the box" stuff like OTA programming (so you can re-flash your project without having to move it or plug anything into it).
