Good evening! Yes, it was connected in a real device. One inscription appeared, but there is no firmware data. If something has to go through the Rx-Tx pins, then I can look in the oscilloscope. As for decryption, I don't know if it will work out or not, but will I see the signals if there are? Chec...

Good evening! I hope this is how you describe it, if it were so it would get rid of many confusing situations. I made the program, it's in the attached file. I uploaded it to the controller, but no miracle happened, only the inscription "FirmwareTest" appeared. Perhaps the module sent the firmware d...

Good evening! Thank you, today I will try to do as you said, but I do not understand how the controller will receive a message from the esp-01 module...some kind of witchcraft...

Good afternoon! I decided to check with an oscilloscope in the FC program what happens on the legs of the controller when the esp-01 module sends data about its firmware, there are no signals on the Rx leg, this means the esp-01 module sends firmware data via wi-fi or this module is visually present...

Good evening! I looked at this web page with different examples. I started with the first example. There is its own layout board and the task is to get the firmware version and display it on the screen. I launched that program from "help", called "Firmware Test". Well, I don't know if it should work...

Good afternoon! Thanks for the clarification. I just thought it works like in a computer (I've been doing it for so long that I don't remember how), when you send a command, and the answer comes how it should look (characters, spaces, dashes, and the like.)

Good morning! Thanks for the clarification, but the answers are not to the point of the questions asked. I have now tried the command "AT+CIPSEND=" (as in your program), send it from the esp-01 module connected to a USB-TTL adapter, using terminal programs, I thought it would give me the length para...

Good evening! Thanks for the link, I'll look at the examples tomorrow. I wanted to ask you about the lesson "ESP-ESP_Send" from March 15 , 2023. The questions are written in the screenshots of the program.

Good evening! Thank you very much for clarifying the questions you are interested in. It began to clear up a little. I keep going on.

Good afternoon! I'm sorry, maybe you misunderstood me or I didn't understand you. When information is transmitted from one esp-01 module to another of the same module without using an external router, do these esp-01 modules create a network among themselves and it can have any name or only the name...

Good evening! You have data reception in there in the program "ESP-ESP_AP_Tx" in the subroutine "Get_Data", you write that the data needs to be converted to a text format, so they come to you in a text format? and the macro component itself is empty, there is nothing there and it is not marked in an...

Good evening! Sorry, there is another question: 1) there is a data transfer in the program "ESP-ESP_AP_Tx" in the "ESP_Send" subroutine-from the beginning you send a text command "attention, data transfer is about to take place" or "AT+CIPSEND="-why is there a "=" at the end, because the command wit...

Good evening! I thought a little presumptuously that all this could be repeated in a few hours...I decided from the beginning to try to make a similarity of your programs, where there is a connection between two esp8266 modules. I had to find out from the beginning what "OSCCON" is, then what 0xF0 i...

Good afternoon! Thanks for the link. Today I will take a look and try to do this on my components.

Good morning! I will be able to respond and do something about this project no earlier than 4 p.m. on Sunday.

Good evening! Most likely, two possibilities will need to be considered. One of them is when there is an access point in the form of a router, as now, and the second option is when there is no router and we will make point-to-point access.

Good evening! Happy Victory Day! Today I connected the expansion board for the esp8266-01 module (the module is inserted into this board and there is a place for soldering wires, suitable for "laboratory work") with the controller and indicator board. I would like to clarify with you what other prel...

Good evening! I will be able to get in touch on 9.05 after 16 hours.

Good afternoon! Yes, you understood me correctly. Several controllers receive data from sensors and send it to the controller, which, depending on the program, performs certain actions. As for the current project, I haven't put everything I need into a diagram yet, while I'm working on it.

Good evening! I found a small circuit on the network-a bidirectional logic level converter, but I did not use it, I will try it in the simulator, but the voltage divider looks simpler and more accessible... And as for connecting several controllers via uart, I was interested because there was someho...

Good afternoon! Now, apparently, I need to connect each esp-01 module to my board with a controller and an lcd 1602 indicator? The power supply should be 3.3 volts, and the outputs of the Rx controller should be connected to the Tx output of the ESP-01 module and the Tx output of the controller to t...

Good evening! Thank you chipfryer27 for your mentorship and patience in finding the right solution to technical problems. I have reprogrammed the second module and on Monday after 16:00, if you have the opportunity, strength, patience and inspiration, we will continue to solve the problem of data tr...

Good evening, Abhi! Happy Holidays to you too! Thank you for taking a moment and writing to me! Yes, I am very grateful to my mentor Chipfryer27, thanks to him I received such knowledge and experience that you can’t get anywhere or from anyone. You talked about patience, it’s more likely not for me,...

Good afternoon Happy holiday! Today everything worked out on the first try. It is necessary for the programmers of the flovcode program to write more detailed instructions for these manipulations with the ESP 8266 module, otherwise without a glass or two you will not understand this witchcraft. The ...

Good morning! Today I dreamed that I was untying a knot. Maybe sleep and your advice will help, but first I would like to clarify: 1) do you write that the uart pins could change after the options that we have already tried, in other words, can you try connecting RX-RX and TX-TX? 2) you write that y...
