FOTA with ESP8266 (GIT8266O-303)

[dipendra77]

Hi,
I am working on a project based on ESP8266. I wanted to explore about the OTA upgrade feature of EPS8266. The example for simple OTA does not seem very clear. I wanted to know how do we upgrade a device which is at a remote location with a new firmware as we keep pushing changes every now and then. Can anyone please help me with the issue.?

@dipendra77 Please take a look at examples/system/ota/native_ota/2+MB_flash/new_to_new_no_old if by HTTP.
or examples/system/ota/simple_ota_example if by HTTPS.

Hi,
Thank you for responding. I understood the simple OTA example and can successfully upgrade to a new binary using the same. Sorry I was not very clear about the issue earlier. The actual problem is that these examples expect the device and the PC ( On which the https server is running) to be on the same network and a serial connection between the device and the PC. My use case for FOTA would be more like upgrading the firmware from a remote server ( a web server probably ) and without any physical connection between the device and the Host server. Or pushing updates through an android app and distributing it to all the devices on the field , directly to the users.
I found this on the web which does something similar with Arduino IDE, here is the link: https://github.com/espressif/arduino-esp32/blob/master/docs/OTAWebUpdate/OTAWebUpdate.md
I wanted to know if this is possible using the RTOS_SDK for ESP8266 / ESP32 ?
Any help will be appreciated.
Thank you.

For the first programming you have to connect the device to the computer with the help of a cable. You have to! then it doesn't matter if the device connects to a remote server and downloads an upgrade from there. The condition is that the device has access to the public Internet ..
