Fimware for esp8266 esp 01

Christine · February 10, 2018, 12:04pm

Hello , good day to you guys, may i ask, what is the official firmware for esp8266? (i had an esp 01, color black) because i already flash this firmwares:

ai-thinker-v1.1.1-115200.bin
v1.3.0.2 AT Firmware.bin

In my esp 01 and download and use this library coming from github:
(https://github.com/bportaluri/WiFiEsp)
and try the example “ConnectWPA” and test> BasicTest provided in the library, now when i try to upload it in my arduino mega i always have a Timeout when i click the serial monitor.
In theConnectWPA code i followed the instructions:

#ifndef HAVE_HWSERIAL1
#include “SoftwareSerial.h”
SoftwareSerial Serial1(6, 7); // RX, TX
#endif

I connect the RX of esp to Digital 6 of mega and TX to Digital 7 but still timeout
and Digital 18 RX of mega and Digital 19 TX of mega but again timeout.
My hypothesis is maybe the firmware itself is the problem why i can’t use this libary from github.
Guys please help me , i don’t know what to do now. Please

There are lots of versions of the AT firmware but any of them should work for the example you are trying. If you are able to send AT+GMR to the ESP and it returns a version of 1.1.1 or higher then it’s OK.

There are 2 possibilites:

You haven’t wired up the circuit correctly.
The ESP-01 might have a default baud rate of 115200 and Arduino needs to connect to the ESP at 9600.
Try sending AT+CIOBAUD=9600 to the ESP, or AT+UART_DEF=9600,8,1,0,0 if you have fairly recent AT firmware.

@Costas Look at you, troubleshooting an ESP-01 issue

@Lesproux31 You are missing your gas mask … and look a lot like Steph

Are you aware that the Mega doesn’t use SoftSerial for pins 18 & 19?

Have you tried following any of the Blynk Help Center documentation or are we troubleshooting a non-Blynk related GitHub Library issue?

You can also try the Mega Serial1 example - https://examples.blynk.cc/?board=Arduino%20Mega%202560&shield=Serial1&example=GettingStarted%2FBlynkBlink - It is defaulting at 9600 but Serial1 will handle 115200 if your ESP is preset for that.

Ok sir , i’ll check the wirings.

Costas · February 10, 2018, 1:00pm

baud rate is more likely to be your problem.

Christine · February 10, 2018, 1:05pm

Someone taught me that i should connect the esp01 rx to rx of mega and tx of esp01 to tx of mega. i didn’t aware of mega doesn’t have a softwareserial pin. I just want to know if blynk had a firmware for es01 to use blynk library. I ask many forum about my problem but no one can answer.
And how do you know steph by the way ?

Gunner · February 10, 2018, 1:10pm

Blynk doesn’t have any AT firmware for ESP-01 That is an Espressif thing, not a Blynk thing.

Mega doesn’t need SoftwareSerial libraries for any of it’s three auxilery hardwaere serial ports - Serial - Arduino Reference

Christine · February 10, 2018, 1:15pm

My connections:
RX of esp01 to RX of Mega (0)
TX of esp01 to TX of Mega (1)
CHPD and Vcc to 3.3 of Mega
Ground is to ground.

Pins 0 & 1 on the Mega are used by the USB port… use Serial1 pins instead, and NOT with SoftSerial… as mentioned a few times now… Seems to work just fine for my ESP-01/Mega combo

Christine · February 10, 2018, 1:20pm

The code says:
“#ifndef HAVE_HWSERIAL1
#include “SoftwareSerial.h”
SoftwareSerial Serial1(18, 19); // RX, TX
#endif”
So should i erase the #include statement here? and hey how do you know steph? i’m just curious.

Costas · February 10, 2018, 1:25pm

No voltage divider?

Christine · February 10, 2018, 1:26pm

No sir, i haven’t .

Costas · February 10, 2018, 1:27pm

For the trashy ESP-01 you need to voltage divider but better to get a real ESP.

is the esp01 working now?

I don’t… Google does

Most users here are male, so some new members use imagery to “encourage” assistance or get links clicked

Normally not a problem what your avatar is, but when combined with a fictional characters name and questions that have no Blynk related issues… as a moderator I just need to make sure our regular users are not being spammed or phished.

And on that note… this is a Blynk forum… we can help you with Blynk, not that other GitHub library you seem to be trying.

Christine · February 10, 2018, 1:39pm

No, didn’t use some “imaginary” people to assist me. I logged in using my twitter , apologize if you thought i am spamming this blynk forum and i had so many forum that asked the same question but no one can answer. And i will use now my true name

Costas · February 10, 2018, 1:41pm

Looks like you need newer firmware for that library.

Gunner · February 10, 2018, 1:44pm

@Christine Now if only there was a link (in green… way above - ) to official firmware somewhere…

and now here as well. I think ESP8266 AT Bin V1.6 should do the trick.

Christine · February 10, 2018, 1:47pm

Ok sir , i will flash a newer firmware now.

Costas · February 10, 2018, 1:50pm

Don’t forget to set ESP baud at 9600 after flashing the new firmware.
