Using Arduino. Networking, Protocols, and Devices. doles August 27, , am #1. Hey all, I’m trying to download a file(jpg) and store it in SPIFFS to later be used to draw using JPEGdecoder library 26/09/ · I need to download a file from an HTTPS service into SPIFFS. This file is fairly large and when downloading using HTTP it is not a problem. This is what I have done in other projects for example with the json streaming parser. It looks like HTTPS is instead loading the whole thing in RAM, and then it crashes

I am observing at behaviour that I would like to confirm being as expected. I need to download a file from an HTTPS service into SPIFFS. This file is fairly large and when downloading using HTTP it is not a problem.
This is what I have done in other projects for example with the json streaming parser. It looks like HTTPS is instead loading the whole thing in RAM, and then it crashes. Is there a way to do it without lording it in RAM?
Thank you. The text was updated successfully, but these errors were encountered:. Sorry, something went wrong. I need to download a file from an HTTPS service directly into SPIFFS, as I used to do successfully with plain HTTP with files larger than the available RAM e.
json files. The sketch shows about 30K free heap before the download starts. The download fails if the file is above 8k or so. The sketch gets stuck, no stack dump.
It seems the file is loaded first into RAM and does not go directly to SPIFFS. Is this the expected behaviour? Is there a way to download it without copying it into RAM? Check this. Hi d-a-v, thanks for the hint. I did implement it and in fact i confirm it works!
HOWEVER i see a behaviour that i would like to confirm is as expected and not a memory leak. When the line: BearSSL::WiFiClientSecure client; is executed, heap goes down by about 5K. These 5K are never deallocated, even if the class that downloaded is long gone. To me this seems not right. CC earlephilhower. MarcFinns that's a feature, esp8266 download file to spiffs, not a bug. If you have a global WiFiClientSecure, it will obviously never go away so you'll esp8266 download file to spiffs up with that chunk never freeing.
I'd recommend a dynamically allocated object i. esp8266 download file to spiffs one that's stack-local inside a function that exits, to ensure it's deleted. The 4. It seems a bug. You get the behavior with both types of allocation and it can be reproduced with 2 lines of code - see below. Is this sufficient to report the bug? begin ; delay ; Serial. getFreeHeap ; delete client; Serial. getFreeHeap ; }.
void loop { Serial. getFreeHeap ; while 1 delay ; }. MarcFinns. It does not work for me, issue I used it to download every half esp8266 download file to spiffs 24 images of a weather animation.
In the web service I can specify the jpg size and I now use x This means images are k depending on the cloud patterns. It would not work with axTLS but it works nicely with BearSSL. How large are your files? I still have an issue, e. Esp8266 download file to spiffs have seen an issue that BearSSL takes up to 48k from heap. BearSSL works with less than that.
Have you tried reducing the buffers, not checking the fingerprint and reading the file in chunks? see example below, hope it helps. let me know. I tried to update my MCVE sketch to use with BearSSL to show the issue. But my MCVE sketch works. So I need to analyze my issue with download to draw on e-paper from start. ZinggJM this thread has gone in several directions already, and is getting a bit long.
