ESP8266 Community Forum

Dear all member!
I've finished a project Mega2560 & esp8266, esp8266's like picture. I used Sky phone & Asus phone to access in wifi, then accessed in 192.168.4.1 IP by Chrome okey! But when I used Iphone & Samsung phone, I just only accessed in wifi ok, then I couldn't access in 192.168.4.1 IP by Safari of Iphone & Chrome of Samsung. Please help me for accessing in 192.168.4.1 IP ok with all type of smart phone! Thank you.

What firmware is flashed into your ESP, is it something you brew yourself or are you using the original AT-firmware?

I've never had any problems connection and browsing with any of my phones (cheap Android China phones or my Samsung Galaxy S6 and iPhone 4).

BTW: your board is an ESP-07; if you want to use the extenal antenna connection, make sure you remove the SMD component marked below:

Thank you!
I will check its firm-ware again, then update.
I will notify result soonly.
