Can I transfer an entire file from ESP32 Server to ESP32 Client via Bluetooth Low Energy. I am only able to send file by sending packets but not the entire File?
if you wish to transfer files why not use WiFi and FTP?
e.g. see ftp-server-on-esp8266-and-esp32
I need to use BLE instead of Wifi. So that the device consumes less power. And battery life will increase dramatically.
OK - try a web search for ble file transfer - a there maybe some useful links, e.g. ble_file_transfer
you could possibly adapt TCP FTP code
