How to program the ESP32-CAM directly via the CP2102?

Welcome

This time I am asking for advice on how I can program the ESP32-CAM camera module. As you know , this module does not have any USB type connector and for programming you need to use a USB converter . I have one with a CP2102 chip. After connecting the converter to the computer , a red LED on the board lights up. In the manager the converter is detected as Silicon Labs CP210x USB to UART Bridge .

In the preferences of the arduino program , where to look for new modules writes this page

https://dl.espressif.com/dl/package_esp32_index.json

Then, in the tools tab, I search for new cards and a window pops up showing the search process.
After several seconds of searching, an error pops up saying that it is not possible to connect to the page:

Error descargando http://downloads.arduino.cc/packages/package_index.json

I do not understand why it searches on one page and shows the error on the other


Yesterday, I browsed the internet all afternoon and night, but nothing could be found to detect the module.
My windows is Windows 7 , could it be the reason why I get an error because I have the wrong JAVA version? Because it does not update

Greetings

Is the ESP32 board manager installed in the Arduino IDE?

https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/boards_manager.md

Hello

And how can I check this ?

In the Arduino IDE board manager.
https://www.arduino.cc/en/guide/cores

Yes, I checked there and there was nothing. I deleted version 1.6 and installed the new one, the latest 1.8.10, and it shows esp32 espressif. So now it is OK

Now I have to find out how to program the camera module

So far thanks for your help, if I have more problems I will write again

Added after 43 [minutes]:

Unfortunately , I still have to ask for help.
This is what is now popping up for me when monitoring the port


.


.

Comment out '#define CAMERA_MODEL_WROVER_KIT'.
Only '#define CAMERA_MODEL_AI_THINKER' should remain.

Hello
I have it written down like this in the program, because I don't know much about programming I don't really understand what you mean, i.e. what to change

It should be like this:
.

or so ?
.


I should add that in the further part of the programme it is written as follows

.


Still nothing



still can't see it

You still have not made the change I wrote about in the post #8 .

.

I now have it written like this and while programming it pops up an error like this. Surely I have done something wrong

Ps
Please , write as if for a throng because I know nothing about programming and find it hard to understand anything even if it is simple

No USB communication with ESP32-CAM when trying to load the program. The program itself has now compiled correctly.

I have re-entered
This is what it looks like after the complication

.


And this is how it looks after uploading , something is wrong

It appears that the program has compiled correctly and loaded into the ESP. Next is something in Spanish .

I use the programme in Spanish jeje
And it says so

Library not appropriate found in C user /Jose / Documents / Arduino / Libraries / Tools : folder ( or maybe file ) with header (.h) not found in C - user - documents - Arduino - libraries - tools

If I understand correctly I am missing the library

Have you checked what appears in the serial port monitor in the Arduino IDE after loading the code and restarting the ESP? The monitor speed should be set to 115,200.

.

This is what it looks like. At the moment I have a jumper on the ESP module for programming.
Should I remove it ?
In order for something to show up in the window I have to press reset on the module board.

Shall I delete it ?

.
Yes.

Ok , deleted but nothing shows up
Should I press reset?
Or should I disconnect and reconnect the module

wosiekpl wrote:

Can you disconnect and reconnect the module

.
You can do it that way too, but I would think you would be removing that jumper with the ESP power off.

No , I did the live. Now I have disconnected and reconnected



It seems to be better
And to see what the camera sees I need to connect to the address indicated. I understand that I need to use a program with which I can preview?

It works, I entered the address and it worked.

Thank you, many thanks for your help

Yes, nice viewing .

OK. Many thanks again. I'll play around with it a bit for now and see what it can be useful for

Hello

I am revisiting the topic , the camera works fine but only at home. It is connected to the router via Wifi and in the mobile phone I can watch what it sees but also only when the mobile is connected to the Wifi. I thought that outside the house I would be able to watch but it turns out not to be the case. It follows that I will have to do something else to be able to view the camera image outside the house. I want, for now in the form of tests (because neither the quality of the image nor the voice, does not allow much. It is known that for such money one cannot demand much) to control what is happening on the roof, i.e. control my shortwave antenna.

Greetings

Use an external antenna for the ESP32-CAM module, the one built in on the board is not the best.
This is explained at this link, under point 7 "Weak Wi-Fi Signal":
https://randomnerdtutorials.com/esp32-cam-troubleshooting-guide/

Hello

I have already ordered ( yesterday ) , This is it



And now I will take to reading what you have given me

Thanks


Ps

As I wrote, the antenna is already ordered. I just had a quick look at the website you wrote about . I will do further tests at the end of the week. But it seems to me that the problem is not related to the antenna because the signal relay from the router is located 1,5 mtr from the camera.
The router is in the living room and the camera in the room, in a straight line it will be about 6 mtr but between the camera and the router I have mounted a signal relay which amplifies the signal from the router

I have a signal relay fitted which boosts the signal from the router

.
I also have something like this at my place and sometimes the ESP "catches" the WiFi connection not from the extender but from the main router even though there is a weaker signal. This is also when the connection breaks down.
You can try to connect to the extender using the ESP8266WiFiSTAClass::begin() function, where you also specify the MAC address of the AP, but I haven't tried that - it seems to have appeared only in the latest version of Arduino HAL for ESP8266, version 2.6.

Yes , only that I have a router saved in the program with an EXE extension . The router in the living room has the name abc.123 and the relay has the name abc.123_EXE so I guess it can't connect.
As I wrote earlier , at the end of the week when I have more time I will try to review the exact page you are writing to me about. In the meantime maybe a new antenna will arrive.
Best regards
