Unfortunately, it turns out it's a lot of duplicate effort for us to maintain both bbs.espressif.com as well as esp32.com, and as such we decided to merge them. As activity over the years for this forum has gone down, esp32.com will be Espressifs main forum from now on; we created a subforum for ESP8266-specific things. Hope to see you there!

I noticed a strange behaviour using the AT+CIPSTA_CUR command and I would like to ask if there is something known about it or
maybe I'm doing a mistake.
The problem is, if I use IP address like 192.168.1.41 everything works, but if I use 192.168.001.041, I can not connect to
my network . The command AT+CIPSTA_CUR however is accepted and the default IP is used instead.
With other words is there a problem with leading '0' within the IP string?
Thank you for an answer.

And used the EspTouch app for iPhone and used the EspressifTouchSDK 1.1.0 for iOS. In both cases, once the device receives the SSID-Password, it does not send a success response back to tell the app that the smartconfig has successfully finished.
Is there a way around this?

My expectation is to have the board configured in Download mode by the tool itself, without the need to press any button on the devkit.
It is not the case

I noticed an interesting project on the Github that uses ESP8266 and Non-os code.The project
documentation states:
qz]Install ESP8266 gcc. See
https://docs.espressif.com/projects/esp ... setup.html
Fetch ESP8266_NONOS_SDK from https://github.com/espressif/ESP8266_NONOS_SDK
Point environment variable ESP_SDK to the SDK directory.
Install esptool.
Since I already have a MSYS system that compile gcc code for AVR devices
(http://siz.hu/en/content/sd2iec-develop ... nt-windows), I tried to add support also
for xtensa-lx106-elf and ESP8266 NONOS SDK by next 7 steps:
1. Download the toolchain 8.4.0 from
https://docs.espressif.com/projects/esp ... setup.html
2. Extract zip on C: ,result is new folder C:\xtensa-lx106-elf
3. DoWnload zip from https://github.com/espressif/ESP8266_NONOS_SDK
4. Extract zip on C: ,result is new folder C:\ESP8266_NONOS_SDK
5. In the .bat file that start Msys, I add next 3 lines:
set Xtensa_PATH=%CD:~0,2%\xtensa-lx106-elf
set PATH=%PATH%;%Xtensa_PATH%\bin
set ESP_SDK=%CD:~0,2%\ESP8266_NONOS_SDK
6. Run the Msys and test:
xtensa-lx106-esp-gcc -- version -> print version 8.4.0 and other stuff
printenv ESP_SDK -> C:\ESP8266_NONOS_SDK
7, run sh script in /C/ESP8266_NONOS_SDK/driver_lib
./make_lib.sh driver
--------
But this not work...
When I start the make command in the project folder, compiler did not find ets_sys.h. I solved
this by simply add the missing .h files from SDK into the project folder.
Now compiling started successfully and produce object code (.o files), but then the linker
reported cannot find -lhal and few other missing parts.
It seems that the xtensa-lx106-elf does not know where the SDK is located. What did I do wrong?

The following 2 line message are shown from serial port right before rebooting, then it will reboot immediately:
"tx rts error 0x16"
"mac 1370"
I am using arduino IDE with ESP8266 sdk v2.7.4, nonosdk, I have spent so much time to identify the issue, however I have no clue so far.
I suspect it has something to do with Nonos_sdk, and but there is no source code to let me tracking down where and how the issue occurs.
NOTES: I must use ESP8266 SDK v2.74 (or lower), but cannot use greater than v2.7.4, since I need to use lwip v1.4 compile from source option, and high version sdk doesn't have this option but only lwip v2.0, which is not suitable for our project.
Please help to resolve this issue.

What is the rational for "registration"?
As understood there's a limit of 10 encrypted devices, or 20 unencrypted devices; is this due to a fixed registration data array size?
If there is only a single receiver, it appears that any number of senders (ESP8266, or ESP32) can be used; is this true?

We are long time user of esp8266 and running thousands of live devices in home automation category on this chip. However a small limitation is holding us to develop some more interesting and innovative products.
Requirement: We have a requirement to run both TCP client (connected to our cloud server) and TCP server (on which some TCP clients can connect to ESP) at the same time.
Limitation: While we do not get any error when setting up TCP client and TCP Server at same time however we receive data only on connected client. Other TCP clients can not connect to TCP server. If do not connect TCP client from ESP to cloud server, TCP server on ESP very well accepts TCP client connections.
TCP client + UDP server also works perfectly.
Is there any work around to this limitation of TCP client and TCP server running on ESP8266 at the same time?
[Removing this limitation will certainly help to increase footprint of esp8266. With this limitation we are getting forced to look for alternatives]

As I struggled to use the spiffs on the esp8266, I decided to rename my work in progress repo to make it into a tutorial on "how to flash and use spiffs as a webserver".
I was trying to convert the arduino tutorial "A Beginner's Guide to the ESP8266" into the ESP8266_RTOS_SDK. Even if the conversion is not complete, the main part being the problem with the spiffs documentation of the esp8266, I hope it will be helpfull for some of you out there !
As I see, I think this solution is quite different than the Bernard's approach.
Here's my WIP spiffs webserver's repository. I hope I didn't make too much errors, easy to use for everyone (not just me on my computer...) and it will be a good help for beginners and others.
At the moment what it does :
- Integrated into the project's Cmake file for auto compiling and flashing.
- Create an image of the files to be flash into the spiffs.
- Flash the spiffs binaries with the code each time (need to comment the line in the Cmake file. Would like to add an option to be able to "flash" or "flash all").
- The esp can browse all the files inside the spiffs.
- The esp can fetch all the files asked and send it to the client (needs to modify the sdk).
- Basic threadless websocket client gestion (code from IBM)(the esp was rebooting with more than 3 websockets threads, no idea why, ressources ?)
TODO list :
- Adding the websocket protocol.
- Adding led control (as seen in the exemples).
- Adds more (refactor) comments in order to match Doxygen's style.
All criticism is welcomed and higly appreciated, my work is far from perfect and bugs free.
Regards, Extro.

I have designed a prototype titled Smart Blind stick for disabled people. The project is working fine and now I am thinking of designing it as a product. Right now I have designed it on wero board but now I want to design its PCB design.
I am new to PCB designing and thinking of hiring a freelancer to design the PCB board.
So, my questions are:
1) Can I get the PCB design of ESP32 boards and can I select the features to add. i.e. I don't want multiple capacitive touch pins, I just want a single touch pin. So, can I remove the other pins?
2) Should I go for flexible PCB design, as the space where I am going to place it is too small. So, I am thinking of using flex PCB, but I have heard that its expensive. Can someone please guide me here? Need some PCB vendors to get an idea about PCB designing?
Thanks.

I have completed a prototype on the ESP32 module and now I want to design its PCB board. I want to remove a few features of the ESP32 board in my custom design i.e. ESP23 sensors, touch pins as I am not using them. So, can someone please help me out and provide me the link to download Gerber files of ESP32 board.
Moreover, I am confused in the selection of PCB type. My product is going to be placed in very small space so it should have a small size. I am thinking of designing flexible PCB or a mix of rigid flex PCB. Any help would be appreciated.
Thanks.

Would you classify this forum as I've described?
Is discussing Arduino frowned-on here?

I have multiple master sending information to one slave.
My masters are ESP01 and my slave is ESP32.
I am having problem when try to use key to encrypt the message.
The main part of the code:
Code:
esp_now_add_peer(mac,role,channel,key,size) is it possible? Does somebody proof this feature?
Thanks in advance.

I am pretty new to the ESP8266 IDF and I have some questions.
I have created a project with different components, but for example I would like to import FreeRTOS in the #include section of my component source files.
I know I have to write it in the "component.mk", but I cannot make it work!
The make list-components shows everything correctly, but I cannot build correctly because the compiler cannot find the header files outside the "main" directory.
Please can you help me!
Thank you in advice.

I found something which IMHO looks like a bug in the firmware (bootloader?) of the ESP8266-01 I have.
Per HW design the default level is HIGH (3.3V) for GPIO0 and I think GPIO3 too. After power-on both pins
go for a very short time LOW. It is short, maybe 0.1 sec but long enough to be noticed by anything controlled
by those pins.
In my case, I have the ESP8266-01 sitting on a relay-board labelled: ESP-01/01S Relay v4.0 TB:IOTMCU.
This short LOW triggers the relay.
This makes it close to impossible to use those GPIO pins for any serious use with a relay..
AT+GMR
AT version:1.7.5.0(Oct 9 2021 09:26:04)
SDK version:3.0.5(b29dcd3)
compile time:Oct 15 2021 18:05:30
Bin version(Wroom 02):1.7.5
Is there any way I could change this behaviour?
Any help would be greatly appreciated.
Regards,
Chris

For whatever reason I can't flash anything to them neither using Arduino IDE nor using esptool.py. No matter what I do - I always receive "Failed to connect to Espressif device: Timed out waiting for packet header". For all 5 chips - same behavior.
I can connect to the device using minicom, and on "reset" it greets me with cryptic message
Code:
brlrl
ready
So at least the chips and the board itself are operable.
I tried to connect UART pins of the burner to CH340 adapter I have and then flash it - basically the same result.
I tried to press "flash + reset" and then release "flash" during that "Connecting..." prompt - no luck.
The same USB cable works just fine to flash NodeMCU boards, but I wonder if I am missing something with this one.

After some playing with my ESP8266-01 with Arduino SDK I wanted to install again the AT firmware on it and I failed.
I tried, from the ESP8266_NONOS_SDK-3.0.5, to instal it as follows:
esptool.py write_flash 0x00000 boot_v1.2.bin 0x01000 at/512+512/user1.1024.new.2.bin 0xfc000 esp_init_data_default_v08.bin 0x7e000 blank.bin 0xfe000 blank.bin
No errors during flashing (see below), but then in normal, not download mode, after power-toggle the ESP8266-01 runs amok
the led is blinking like crazy and console gets flooded with garbage.
Could anyone be so nice and guide me to the correct way? Am quite new to ESP8266-01.
Thanks

I bought few ESP-01 Relay boards with a ESP8266-01 sitting on them.
The relay is triggered by the GPIO0 pin. The level of GPIO0 defined (given by HW design) to be HIGH.
However, during boot/startup before the pin goes HIGH for a very short time it goes DOWN, 0V. Short but long enough to trigger the relay.
This makes this combo useless for serious use like controlling a garage door.
This is IMHO a bug in the firmware.
Is it a known problem?
Thanks
ChrisO
