I'm trying to store a 3d array in memory int bigarray[5][12][50]; preferences.begin("my-app", false); preferences.getBytes("calendar", bigarray, 3000); preferences.end(); but it doesnt seem to be working any ideas? I'm not sure what your various preferences calls do, but one thing that sticks out i...

https://docs.espressif.com/projects/esp ... notes.html covers the boot process in pretty good detail.

Hi folks, I'm in the process of trying to upgrade my app from IDF 3.0 to IDF 3.2 and have noticed that it won't even build, saying that there is an IRAM overflow.

I left this running overnight...it's definitely more reliable than it was, but I still get an occasional error like this: E (2085053) i2c: i2c command link malloc error abort() was called at PC 0x4015c4ab on core 1 I make a series of calls to the i2c library every half second, and according to the ...

I also know of no such bug. My product is regularly tested using SSIDs with spaces, special characters, emoji, etc. SSID is defined as and there is nothing special about spaces.

Hi Jason - Thanks for the valuable information. I think you might be onto something regarding the IDLE task. While I don't do any task deletion (I create several at start-up), I wonder if the IDLE task is also responsible for memory management. I don't think any of my tasks should be running contin...

Create a FreeRTOS task that prints out the free memory every 5 seconds or so. Once your app is up, watch the printout and see if the memory continues to go down. If it does, start commenting out code until the memory stops going down. Then find the culprit. I also recommend printing out internal mem...
