How to Upload .bin File to ESP8266 (ESP-12E) via OTA Without Disassembly?

Welcome,

I have a device made on ESP (unfortunately I didn't make it because I have no knowledge). I have a new .bin file with soft for it.

How to upload it via OTA (the device is sealed and I can't take it apart).

I installed the Andruino, downloaded the files to support the ESP8266. but I don't know how to upload the BIN to the device. I can connect to the device directly (it has a client) at address 192.168.1.1. Andruino sees it because in the bottom right I have info that it sees the ESP8266 at the address indicated but what to do next. Maybe someone can spare a few minutes to describe it to me in a simple way. I select the port with the address as in the screen shot but there is no option like upload bin or something like that.... Thank you in advance for your guidance.

And how do you know if the current soft in this ESP will support OTA? It is not that obvious. Under this link there is a fairly accessible explanation of how firmware can be loaded via OTA, but I'm afraid that without getting directly into the ESP it will be difficult.

Here it's displaying information about the configuration that is set up in the Arduino IDE, not whether there is actual communication over the network with the ESP.

If you have the bin file, it is uploaded via the configurator web page in ESP (you should have WIFI manager). Log in to ESP - SYSTEM SETTING tab, indicate the file to be downloaded and follow the instructions.

You can upload using https://1st.bitbumper.de/ota-firmware-update-tool-for-esp8266/
Since the IDE sees your board as Ota it should work.

Gentlemen - the subject is back on the agenda.

ESP 8266 version 4 MB - I need to upload two files - one is "program.bin: which I program from address 0x00000. But from what address do I program the second file "spiffs.bin" from the second memory space? I can't find this anywhere...
