The code is kinda huge to paste here so i'm gonna give the pseudo code here

1. Subscribe it AWS IOT
2. On MQTT message store S3 path and bucket
3. In loop if the message from MQTT has arrived then start OTA update similar to

You need to post the error along with the backtrace. Does that example code work properly for OTA without your code involved?

[thehellmaker]

Let me try doing it without my code.....

Will also post the backtrace. By backtrace you mean the Guru mediation error dump right ?

[thehellmaker]

I used the code mentioned in the link below without any changes

Two things:
Turn on verbose core debug by setting build_flags = -DCORE_DEBUG_LEVEL=ARDUHAL_LOG_LEVEL_DEBUG in your platform.ini.
Make sure you can download the file using curl/wget (although this shouldn't cause a failure). Also add Serial.setDebugOutput(true); just after your Serial.begin.

I've never seen it do that thing with the question marks instead of line numbers. Are you using the latest version of platform.io/arduino-esp32?

Hi! any solution? I have the same problem

[Jeroen88]

@thehellmaker @arilarralde maybe my PR #2259 will solve your issue too
