I have been able to get a large file to be sent in packages over BLE to a characteristic on my ESP32-Wrover-B module (yay!). However, these files can be large (+300kb) so I need to repackage them after all the file data has been sent (in chunks), to then be stored/written in LittleFS.
I have PSRAM with my module that will allow me to store in a larger space directly, however, from the tutorials I have read, you cannot create a global char* variable for PSRAM.
What would be my best approach here? My basic logic here is to repackage all the chunks that are received via BLE into a char* (or string). Once all data received, save it as a file in LittleFS.
