ESP32 OTA over BLE.

I am developing a code for implementing OTA over BLE. Since no BLE OTA available for ESP32 I am creating a custom mehtod. OTA works fine. But the time required is really high. In the process, I am only able to send 500 bytes per second via ESP_GATTS_EXEC_WRITE_EVT. and it almost takes 1 hour 5 minut...
