No ping while opening serial port of arduino connecting to esp 8266 module

sir please help me i have read many post about in esp8266 in the community but it doesn’t help me :anguished:. iam facing the problem because as you see in picture there is no ping .i tried connecting to wifi many time all the time wifi connected but only one time i see the option of ping only once and after that time till now i have no ping option in serial monitor :frowning::sob:.i hope that my problem may be solved .i have firmware version flashed in esp 8266 and using it with arduino .All at command works in 96000 baud rate. @GunnerTechTools @Costas

Yet you missed the parts about formatting your posted code as per the Welcome Topic, I fixed that.

And NOT posting your AUTH so others here can mess with your project :stuck_out_tongue_winking_eye: I fixed that as well but you might want to change it.

Also about NOT calling out regulars to look at your code… everyone, including us, will see it eventually anyhow.

As for your issue… yes there are many topics about using an ESP as a shield for Arduino. And since you did get connected at least once, your pinouts should be fine. Perhaps look at the guidelines about proper power for the ESP as well.

I am new to this forum so I do not know the format.sorry for that.:roll_eyes:
Sir I have checked pinout but there is no ping option
I am powering esp 8266 module via arduino 3.3 volt pinout.wifi get connected then why ping is not there

That is what we have that Welcome Topic :wink:

As mentioned in many of those other topics… Arduino 3.3v pin can NOT provide enough current for most ESP needs… You must have a seperate 3.3v source, typically 500mA+ is a safe bet, and just share the GND between the ESP and Arduino…


But sir if it provide insufficient current then why wifi get connected and ping option not there

Because it is NOT enough current for proper operation… Which part of “use seperate power source” is unclear?


Ok sir,it means I should not provide power to esp 8266 via I will try to power it by another there any hack to power esp 8266 because I have to go to city to buy robotics part which is 100 km far from my village.:neutral_face:

I am from india

@dilkhush PC USB port will give enough power or a mobile phone charger. Or hack some other cable rather than travelling 100km.

Sir I have esp module which require 3.3 volt and my laptop and charger provide 5v if I provide power from them to esp8266 may be it will stop working.will you provide any hack method.

You mean you have a bare ESP rather than a dev board?

ESP as shield… so probably ESP-01… your favorite :stuck_out_tongue:



I was just going to say I hope you are not using a tacky ESP01!!!

See false economy, you now have to drive 100km.

ESP01 $1 of trash.
WeMos $3 super ESP and use your existing chargers etc.

Sir I flashed this version

You need min 500mA I think, so a voltage divider with resistors will probably not do the job well at all… You basically need a 3.3v voltage regulator of some sort.

My WeMos runs at about 90mA and would probably be fine running from an Arduino but those nasty ESP01’s can draw a huge amount of power and interfere with your WiFi.

Then what should I do
