Description

Problem description

Hi everyone, I need help:

I am using the new example for the OTA update. To test this function I am trying to flash the same sketch that is
in use in my wemos d1 lite (1MB) through the UPDATE function of the captive portal. When I try to update a 546 kb file.bin
the operation fails and I get the following error on the serial monitor:

.ERROR [4]: Not Enough Space

WM: [3] -> 192.168.4.1
.ERROR [4]: Not Enough Space
WM: [3] -> 192.168.4.1
.ERROR [4]: Not Enough Space
WM: [3] -> 192.168.4.1
ERROR [4]: Not Enough Space
WM: [2] <- Handle update done
WM: [3] -> 192.168.4.1
WM: [1] [OTA] update failed
WM: [3] -> www.msftconnecttest.com
WM: [2] <- Request redirected to captive portal
WM: [3] -> www.msftconnecttest.com
WM: [2] <- Request redirected to captive portal

but then if I load another 256kb .bin file the operation is successful and the captive portal
returns: Update OK! Device Rebooting now ...

Why does this happen? How is it possible that there are space problems if the sketch in
question is normally loaded into the wemos through the arduino IDE? Can someone help me ?

Settings in IDE

Module: Wemos D1 mini lite

Additional libraries:

Sketch


#include <Arduino.h>

void setup() {

}

void loop() {

}

1mb limit? You need 2x memory

ohh yeah , get a 4mb chip, esp12, nodemcu, or get your sketch down below 512k for ota

you can also upgrade the flash ic on your board, i would just buy some nodemcu modules, they are really good

ok thanks a lot for your support. What I did not understand is: but regardless of the board you have, the maximum limit of a sketch that can be flashed via ota is always 512kb?

No, that is your limit, you need to have 2x the amount of storage for OTA, since you are storing 2 copies at the same time, you are trying to save more than 1mb to your flash, thats how ota works. You can get around this BTW, if you flash a basic tiny OTA sketch first, then ota again to the new one
