I have used nvs partitions of 56 and 60KB by altering the partition table. Capacity is in the thousands.

I am only looking on a phone, but the global is a pointer and the string it points to is probably going out of scope when you delete after getting the JSON. I would investigate the lifetime and location of the string, and who is supposed to allocate and free memory. https://github.com/DaveGamble/cJS...

Thanks ESP_Angus. I had solved it by deleting and making a new timer instead of reusing it. Whilst this seems wasteful it meant that fewer critical sections and rechecks were needed in between timer alarm and start once and so far it is working well with heavy testing. Your input was useful to under...

Bear in mind that writing to flash is slow, and FATFS is slow to read and write. PSRAM is mega fast in comparison.

Very nice work username. OTA_update_posthandler() works nicely. Thanks!

Not a direct solution, but sharing an experience that may help, or maybe you've covered all this and more already...

I normally have a 10s timeout on a netconn that I use for a websocket that serves a javascript browser app. This is good because when a client disconnects disgracefully, the connection is reset and another client can connect (such as when changing between AP and STA, or between devices). However, wh...
