ESP32 Ultimate OTA (HTTP)

ESP32 OTA over many forms!
Crypted functions use AES-256 CBC.

WiFi library: WiFi

HTTP Performance

• Without Flash write and crypt OFF, can go up to 11.3Mb/s.
• Without Flash write and crypt ON, can go up to 7.3Mb/s.
• With Flash write, can go up to 570Kb/s.

How it works?

• Basically, OTA HTTP get file (MIME MEDIA bytes) sent to ESP32 and write in OTA partition.
• .PROCESS() will host HTTP/HTML server, wait new client in HTTP web page, wait upload file and write all new incoming bytes to OTA partition.
• This library will write ALL BYTES received in MIME MEDIA. After start, your external software can't send any byte that are not from the binary file.
• If you use this library in separate task, stack of 4096B should be enough.
• This library can do Factory Reset (last binary burned by USB).

Simple example to use OTA HTTP (Crypto OFF)

WF wifi;
wifi.ap_start("wifi", "1234567890");


OTA_HTTP ota;
ota.init(); //Default port 80
while (1)
{
	ota.process(); //Wait client connection (up to 1sec) and read bytes sent by client in HTTP web page.
}

Simple example to use OTA HTTP (Crypto ON)

Insert your desired key.

WF wifi;
wifi.ap_start("wifi", "1234567890");


OTA_HTTP ota;
ota.init(); //Default port 80

//Set AES-256-CBC KEY and initial IV.
ota.crypto("12345678901234567890123456789012", "0123456789012345");
while (1)
{
	ota.process(); //Wait client connection (up to 1sec) and read bytes sent by client in HTTP web page.
}
