I would like to save data that I am receiving from API calls in a char array. The problem is the data is around 80KB however my Arduino IoT 33 has 32KB of memory. It will save data in a char array that 25000 bytes however when I go to 30000 or above the Arduino freezes. When I copy-paste the entire data to a char array without specifying the size it works fine, however, when receiving data over API in chunks of 10KB it won't save the entire 80KB. Is there a way to go around this? A response will be appreciated.
You can use the flash memory of the SAMD21 MCU used on Nano 33 IoT, if you don't write to often. Flash memories have limited count of write-erase cycles. It is guarantied for 10000 writes.
For Arduino SAMD boards like the nano 33 IoT you can use the FlashStorage library. The library is in Library Manager.
