Good evening! Sorry, I won't be able to do this in the near future, it seems I'm sick and that's why I have a mess in my head...

Good evening! Here I did as you showed. It worked again.

Good evening! Imagine -it turned out without any installation of drivers and programs. I sent the letter "U" from the controller, but the LED was flashing along the way. This was displayed on the terminal window. But it is necessary to remove excess from the forum anyway and I will be a li...

Good evening! Today I tried all possible options: I deleted the drivers of this device, installed others; then I simply deleted the driver of this device and installed the system one, rolled back the system, then another friend told me where to dig into the properties of the port and set the desired...

Good evening! The driver could not be rolled back. The "rollback driver" button does not work, on Wednesday I will try to roll back the system, maybe this event will help to remove an unnecessary driver. But the fact is that I downloaded it from the official website, there was information ...

Good evening! I deleted the program, but nothing has changed. The driver is not being deleted. When I updated the configuration in the device manager, the inscription appeared in the place where the new adapter was: PL2303HXA PHASED OUT SINCE 2012.PLEASE CONTACT YOUR SUPPLIER. When trying to update ...

Good evening! I found a malfunction: I have 2 usb connectors (ports) No. 6 and No. 3 on the front panel of my computer, I determined their numbers when I connected the usb-ttl adapter with the esp-01 module.Everything is fine there, you send the AT+GMR command and get the firmware version in the win...

Good evening! I connected my board and the Tx controller pin on it to the Rx adapter pin and connected the minus of the board and the minus(ground) of the adapter. I checked the connection with a tester, the connections are working. After I turned on the terminal program in which area (they are numb...

Good evening! I bought a usb-ttl adapter, installed the driver from the downloaded site. I saw my device in the device manager, set the communication speed to 115200 (as in the FC program) and in the terminal program, but I did not see any letters in the terminal program window, only the LED on my b...

Good afternoon! Yes, I turned on the "connect" button in the program menu, but something went wrong. I followed the link you gave me. There was a kind of adapter similar to mine, only yours has a quartz resonator, and mine does not. But the chips are the same CH340. But for the purity of t...

Good evening! Now I tried to read the parcels of the letter "U" from the controller using a usb-ttl adapter and the terminal program-nothing happened, the signals go on the oscilloscope, and the terminal program window is empty. I checked it several times -I connected the esp-01 board to t...

Good evening ! Today I will try to add a usb-ttl adapter to the test and read it using the terminal program. Do I need to insert an esp-01 into this module, or do I need to connect the wire from my controller to the Tx pin to the Rx pin of the usb-ttl adapter? and do I still need to connect the &quo...

Good afternoon! I have now conducted an experiment based on your recommendation: I removed the uart module from the program, disconnected the esp-01 module from the board, the program text is LED flashing, and the letter "U" is sent inside. The program was running, the LED was blinking. In...

Good evening! I have now conducted the same experiment, but with the atmega328p controller. Surprisingly, so far nothing has had to be soldered or added, thanks to my mentor :)! But the results are just as bad.: 1) does not show the firmware version 2) the LEDs are flashing, they are yellow in the p...

Good evening! I wanted to say about the adapter for esp-01, there is a board with tracks and holes for soldering and a connector for inserting the esp-01 module. There's nothing else there! I use it to avoid soldering the esp-01 module to my main board. You have confused it with a usb-ttl adapter bo...

Good afternoon! Yes, it really is, only the command without these characters was displayed on the screen, although in principle they should have been displayed. After all, the uart bus doesn't care what text to transmit-signs or letters there and the lcd screen doesn't care what I wrote there either...

Good afternoon! The attached figures show a general connection diagram without details.

Thank you Martin! This chip looks like it has something wrong... It's time to switch to atmega328p, I'll try to make a connection for it. But I will not disassemble the atmega8 board yet, in case you and we are lucky.

Good afternoon! The message was written before I had time to read your message! Now I have compiled a program for sending a text message ""AT+GMR\r\n", then I prescribed in it that it should be displayed on the display, and for some reason there was an abbreviated version ""...

Good afternoon! In all the latest graphs, I try to have the yellow signal of the oscilloscope from the LED, and the green signal comes from the voltage divider, which is connected to the Tx pin of the controller. Now I will try to send a command from the controller to the esp-01 module that you wrot...

Good afternoon! This letter was written before receiving your new schedules and letters, which I will now try to work out. There is no positive news today. In the program, I tried to initialize the uart module, then set the speed on it as on the esp-01 module, it was 115200. Then I looked at the osc...

Good evening! 1) When I loaded the program for sending the letter "U" with the LED flashing, the graph turned out to be normal, unchanged (this is if the esp-01 module is physically disabled), if the esp-01 module is physically enabled, then there is also a signal in the form of a meander....

Good evening! Again, nothing worked out, the message with the firmware version does not arrive. After this command, the program seems to hang. I decided to check if this is the case. I put the LED in the program in the old place where everything worked out. From the beginning, I set a flash test aft...

Good afternoon! Now you can try the example from the "help" menu of the FC program. There was the first program to get data about the firmware version. So I need to connect the esp-01 module to my board, restore all connections with wires and send a command to get the firmware version and ...

Good afternoon! I have now checked the sending of the letter "U" at a speed of 115200. The result is also positive, the signals are the same and the LED is flashing.
