5 years ago Hi, I have the same problem. I'm starting to play with the ESP8266 too.
I get
Panic /home/gordon/Downloads/sloeber/arduinoPlugin/packages/esp8266/hardware/esp8266/2.4.2/libraries/ESP8266WiFi/src/include/DataSource.h:93 const uint8_t* BufferedStreamDataSource
ctx: cont sp: 3ffffbf0 end: 3fffffd0 offset: 01b0 and then stack dump.
Unfortunately, I'm a beginner too. But from what I understand the error is pointing to the
File file = SPIFFS.open(path, "r"); server.streamFile(file, contentType); <<<< something wrong with the stream file.close();
but this is a bit above my pay grade. Gord_W

Hi, thank you for this tutorial, which I found very useful when starting with ESP as a beginner. I've already made some simple sensor projects, but now I'm having something I cannot solve.
I’m working on the data logging part with an ESP8266-01, and somehow I cannot succeed, because I have the following issue. Problem is that when I load the webpage, the ESP restarts. All other things work fine, right until I load the web page. It’s showing the index file (Loading…) only, and simultaneously it makes the ESP restart. The crash is at Arduino15\packages\esp8266\hardware\esp8266\2.4.2\libraries\ESP8266WiFi\src\include/DataSource.h.
Here you find what I have on the terminal: " Connecting .........

It's the same each every time.
What I’ve tried, but haven’t gained success: I found something similar here: https://github.com/esp8266/Arduino/issues/2504 but after checking the code, I realised I already have the improved DataSource.h. I tried it with SPIFFS size 512K (64K SPIFFS) and 512K (128K SPIFFS) options as well.
It would be very much appreciated if you could spend some time with it, and give a hint, what I’m doing wrong, what should I improve to make it working!
Thank you, Blas
