Hello guys,
so i'm using the ESP8266-ESP01 module and i read in a topic about that "wl-definitions not found" when you use the <ESP8266WIFI.H> library and i know it pops up when i don't put "generic ESP8266 module" instead of arduino uno board so i did install the ESP8266 boards pack and tried it but now it's saying this error. i looked it up everywhere,and i saw every topic talking about it but most of them were unanswered and the and the rest were using different modules and using different arduino boards. even asked chatgpt but i did see a topic talking about it and using the same arduino uno board and it was answered.here it is: I keep getting the same message error "esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header" but i didn't understand ANYTHING from @StefanL38's solution also i'm using ubuntu.22.04 version not windows here is the error:
A fatal esptool.py error occurred: Failed to connect to ESP8266: Timed out waiting for packet header
The error-message says your ubuntu 22.04 computer has no connection to your ESP8266-01-module.
You should post a picture of your ESP8266-01-module.
This picture shall show how you connected the ESP8266-001 module with your ubuntu 22.04-computer.
Additionally you should write how much you know about computer in general and microcontrollers especiialy
There is a big chance that you are confused about how to connect such a module to what.
But without more information from you this is just a wild guessing.
this is the module,here are my connections.i connected the TX to the RX of the arduino and the opposite for the RX.i connected the VCC and the CH-PD pin to the 3.3v of the arduino uno board and the GND TO GND.and trust me i checked the wiring like 4 times.
Do yourself a favor and buy an ESP8266-nodeMCU-Board
It is a hassle to use this ESP8266-01 modules.
You need this extra programming-interface you have only two IO-pins left https://de.aliexpress.com/item/1005005999768793.html
You can program a ESP8266-nodeMCU-module just the same as an arduino uno
much more RAM, much more flash
only one ADC-channel.
An Arduino Uno is a 5V device. An ESP8266 is a 3.3V device which means the ESP8266 can only withstand signals with maximum 3.3V
So if you follow the tutorial below you have to make very sure that your circuitry is 100% correct.
The resistors are a absolut must. And the values of these resistors must match 100%.
The program that runs on the microcontroller must be storaged in a way that even in case of all elekctric power is switched off the program stays there.
The memory to store the program in this non-volatile way is called flash-ROM and storing the program inside this flash-ROM is called flashing.
It is basically the same kind of memory like in USB-sticks, SD-cards, SSD-harddisks
For some microcontrollers there are specialised software which is a *.EXE-file.
Most of them will only run under windows.
For more information use google
with keywords like linux flash ESP8266
ok so i'm erasing the firmware already on the ESP8266 and i'm following the tutorial you send and i followed the steps until 7 so here,i typed AT AND AT+GMR and they worked but when i tried the esptool.py --port /dev/ttyACM0 erase_flash command and it says ERROR.what do i do? AND i did plug the USB cable and waiting 5 seconds and then connecting it again
