help with the ESP8266 WiFi module

I bought a wifi module, 5 days ago.

I start to connect everything, and once I finish and try it out I get this:

Ai-Thinker Technology Co. Ltd.

invalid

I can execute AT commands, but I do not know how I can prevent the "invalid" from coming out.

try everything, please I need some help.

Hello,

Please see this conversation I found when searching Google, and let us know if this is correct:

It is probably that saved wifi configs are invalid when trying to do auto-reconnect. Maybe it will disappear when you will succeed to have your first connection.

Hello, thanks for answering.

In what you sent me, I saw this:

"I do not know why / where this" invalid "comes from, especially that I'm not using AT firmware. It is probably that saved wifi configs are invalid when trying to do auto-reconnect. Maybe it will disappear when you will succeed to have your first connection. "

I already connect to a Wi-Fi network and I still get the same.

What I want is to send data to the WiFi module, using Java. The wifi module is connected to the arduino.

And I do not know if the "invalid" problem causes me to send data.

when I connect to the network I get this:

invalid WIFI CONNECTED WIFI GOT IP

Oh, ok,

I have found a reference to the firmware, have you tried updating the firmware?

when i use (AT+RST) command it say invalid in last line

i found the solution that to flash "v2.0 AT Firmware(ESP).bin" and it will be work

Remembering that this kind of module / chip has its own furum :wink:

I tried to update it, look for many programs like ESP FLASH

but I do not know, every time I try to update it, it says connecting and then failed connection.

I am doing something wrong?

Hi

How are you powering your ESP module? (BTW, which module are you using?)

If you are using the Arduino UNO to deliver power (from the 3.3v pin) try supplying power from a different source.

Good point, the consumption of esp8266 is very high:

What is your physical setup? ie. What are you using to update the firmware.

Specify your connections, and the instructions that you are following for the firmware upgrade.
