Test of OTA firmware update using BLE on an ESP32 (ESP-IDF)

I'm doing a project where I have to develop OTA firmware update using BLE (not WiFi) on an ESP32 (ESP-IDF). I'm still in the design phase and I'm wondering how I'm going to test my code. Is there any android/iPhone applications or 3. party programs on the computer, that allows me to perform a test OTA firmware update?

I'm not the developer of the products smartphone application.
