*********F.A.Q.s*************
Q. Getting Error : espcomm_upload_mem failed
A. Make sure that the GPIO 0 pin is connected to ground(GND) and the esp module is getting power.
Q. Can't Install the ESP board?
A. Make sure that you have a reliable connection to the internet.
Q. My sketch doesn't run after I power the the ESP again?
A. Make sure that the GPIO 0 pin is disconnected if you want to run a sketch. Reconnect it if you want to program the board.
Q. I did everything right but I still get error during upload?
A. Go to tools, upload speed and try uploading with different speeds either '115200' or '9600' should work but if they don't try the other ones.
Q.How do I power the ESP without a arduino?
A. You can use a 3.5v LiPo battery or a breadboard power supply like the one I showed at the end(link below) or use 3 AA cells in series.

This was extremely good and the best video on this ESP board on youtube so far after looking at dozens. All the other videos spend 15-20 minutes bullshitting about the board and telling you to download some python ide and a couple of softwares that are totally irrelevant. This literally goes in depth of how to actually use the board and running a simple code on it.

Worked great for me using a Nano! The first few times I tried to upload the sketch it did not work, but then I found that it was because I had a bad USB connection to the Nano. Once I fixed the USB issue it worked great every time. Thanks!
@NACA4412 5 років тому
Finally after many hours it worked. I had to: - connect all the pins to the breadboard, including GPIO2 which is not used; - pull-up RST of the ESP with a 10 KOhm resistor; - use an external power supply on the bus lines of the breadboard; - connect the GND pins of the Arduino and the ESP to the GND of the external power module; - change the Builtin LED to 1. I hope this help other users.
@pastexpiry2013B 5 років тому
THANK YOU SO MUCH. I was convinced that since the code was an example straight from the IDE that it would for sure be working code!! Silly me! I changed Builtin LED to just '1' and it worked right away. There are so many tutorials on the internet that are just plain wrong!

@takatamiyagawa5688 5 років тому
For some reason, I could never get this to work with my Arduino Mega. Worked fine with a USB-to-ESP-01 adapter. I assume you connect the ESP-01's Rx to the Arduino's Rx, because that leads to the USB chip's Tx (an ATMEGA16U2 on the Arduino Mega). I could never get the ESP-01 to respond to the ATMEGA16U2's UART, but for some reason it responded to the ATMEGA2560's second UART just fine (I loaded a program onto the Arduino Mega just to forward data from UART0 to UART1 and vice versa), so I could issue AT-commands via the Arduino IDE's Serial Monitor. Still, the ESP-01 would reset intermittently, and often, when powered off the Arduino Mega's 3.3V line (the ESP-01's output on startup blamed the watchdog timer sometimes, and the reset pin other times... ???). Didn't get this problem with the USB adapter. I still have to manually short the ESP-01's GPIO0 to ground on startup if I want to load a new program, because the adapter I got doesn't have any mechanism to do that itself. Probably learned more about what's on my Arduino Mega, and what's on the ESP-01, due to so much stuff not working for a while. >.< Also had to replace LED_BUILTIN with 1 in the blink sketch for that to work.

Whenever you connect Tx to Tx, Rx to Rx, and GPIO0 of ESP8266 to GND, you are downloading firmware into ESP8266. After that, you no longer able to use AT command to communicate with your ESP8266. You need to re-upload the ESP8266 firmware into ESP8266 to enable you to use AT command.

No, I said it correctly. If the Arduino itself was communicating with the ESP then you would be correct. But we are actually bypassing the Arduino completely and hence the weird connections.
@thomasweyermann5848 3 роки тому
Oh okay that does make more sense. No matter what I tried, I could never get this working through the Arduino (presumably because I didn’t have the necessary capacitors, resistors, or possibly computer drivers), so I’ve been using a hybrid of a 3.3V power supply and my FTDI adapter which does require rx-tx and tx-rx.

sir can i ask something, i had this kind of project the wifi base electric fan microcontroller the components are relay 8 module, arduino uno, esp 8266 and 12v dc electric fan. its all working together but there's some problem the esp 8266 have been restarting because of the fluctuation of the tx in esp there is current flowing on that pin thats why our project is not working properly the esp keep shutting down. what can you suggest ? thank you!
@LiveSparks 6 років тому
+Vironica Macabenta There should be no current flow on the tx at all. That is a logic pin and works only on voltage. To prevent voltage fluctuations, connect a capacitor between the vcc and ground of esp as well as the motor. Also make sure that there is a flyback diode across the relay to eliminate voltage spikes.

I have a answer to this problem... 1. Follow steps of this tutorial correctly . OK 2. Connect RST pin of ESP8266 to Ground for just 1-2 Seconds before Programming...and then remove it after 1-2 seconds.. this is because, i think the reason could be Arduino IDE will able to show during uploading the flash memory found on ESP8266 and some more details. IDE can able to detect the flash memory of ESP8266 and then it will successfully uploaded.

Hey thanks for the great video. I have a question on the esp8266. I am trying to use this as a door sensor where it will tell me when the door opens and closes based on a reed switch. I also want it to go to deep sleep just after it sends the MQTT message for close state. I’m confused about the GPIO0 connection. If i connect the GPIO to ground, can i not send this pin to go low which means close and high when open? So i have my reed switch connected to GPIO0 and ground. Then i have a jumper between VCC and CHPD. Am i doing something wrong? My code basically set pin 0 to digital read ? Let me know if you can help...great video btw
@LiveSparks 6 років тому
It is not recommended to connect anything to the GPIO0 because if the hardware pulls it to GND then it will take the ESP into programming mode and your code won't execute. If you really have to connect something to GPIO0 then make sure that it's pulled high on boot. I would recommend that if you pursuing a serious project then buy one of the ESP12 boards like the wemos d1 mini.

i have this esp-01 adapter for esp8266, in that adapter, there are 4 pins, can i use that adapter to connect it to arduino nano and program esp? please assist me as soon as possible. this is for a university project

+sameera gamage I don't know which adapter you are talking about so I can't tell you anything for sure.
@sameeragamage352 6 років тому
this is the one i am talking about, when i try to connect the module via this adapter, there is an error shows in the arduino ide "espcomm_upload_mem_failed" what is the reason, btw, thanks a lot for replying
@LiveSparks 6 років тому
+sameera gamage this error means that the connection are wrong

Ciao, perchè alcuni collegano tx con rx arduno e rx con tx di arduino? Cioè il contrario ? Perchè? Grazie mille
@LiveSparks 5 років тому
This is because we are bypassing the arduino to communicate with the ESP.

What resistor value did you use? Thanks!

yeah!

I have connected the ESP8266 with Arduino UNO with the same connections shown in the video but when I was trying to run the blink code it is showing the error that selected serial port(Port name: COM3(Arduino/Genuino UNO) doesnot connect with your board. It is the only port available when I am connecting the device to my laptop. What can i do to solve this . Waiting for the reply

Can you upload any code to only the arduino? If not than try changing the cable.

Excellent my friend, very well structured tutorial..

ok, now i get it! you use arduino nano board just to use its ch340 usb-uart chip. That is why nano's reset pin is permanently hooked up to the ground and tx-tx and rx-rx pins are connected. thank you

You recommend putting a 3.3 µF Capacitor between ground and vcc? Didn't understood that

+Scorpiaa_ | YT: ScorpiaDev Its not necessary but can help smooth out any fluctuations in power.

What is the value of the resistor you are using?

Hi, I got a question about your video. The upload worked (blink sketch) but the LED didnt blink. Are you sure that the rx pins are working with 5 V because i read that: "Remember to always use a level converter for the RX pin into the device as it is not 5V tolerant." I used a 100 µf condensator and a 120 ohm resistor btw
@LiveSparks 7 років тому
+De Al If the rx, tx pins were connected wrongly then you would have had an error on your hands not a successful upload. Here the problem is that after the upload, the esp is not resetting correctly.
@deal5355 7 років тому
Thank you for your quick response :) . Do you have any advice for this problem ? There is one other thing I was wondering about. Whats does the connection between the reset and the ground on the arduino board do ?
@LiveSparks 7 років тому
+De Al The arduino is being held in a constant reset so only tge esp gets programmed and not the arduino.

Thank you very much :)

For some reason you cannot use a jumper cable when connecting CH_PD to VCC. (you get a failed to upload error). Use a 10k resistor instead and it works perfectly
