Does the OTA update supports Redbearlab BLE Nano now without pushbutton?

Does the Platform IO supports the OTA for BLE Nano without the need for push button? Also, I find that the board feature seems old in the board list. The BLE Nano is v1.5 now with 32KB ram and 256KB flash.

Is there a guide on how to perform BLE OTA firmware update/upload? I saw the example for ESP8266 which is IP based. How is the configuration like for platform.ini?

Wait, the OTA is still IP based? Where the remote machine is needed to physically connected to the BLE module? No BLE OTA?
