# Advanced ESP32 BLE provisioning profile.
#
# Adds the SmartESS-compatible BLE Wi-Fi pairing: the EyeBond Local integration
# can put the bridge onto Wi-Fi over Bluetooth, exactly as it would a factory
# collector (an alternative to the captive portal). BLE provisioning needs
# on-chip BLE, so it is ESP32-only, and it requires the esp32_ble_server: block
# below.
#
# IMPORTANT — image size: BLE (Bluedroid) + Wi-Fi is large, and the real flashed
# image is ~12 KB bigger than ESPHome's reported "Flash %" (IDF image header +
# padding). On the default 4 MB app slot (~1.79 MB) this profile only fits once
# api:, captive_portal: and the baud select: are dropped — otherwise the image
# silently overflows the partition and the board boot-loops
# ("Image length ... doesn't fit"). They are therefore omitted here:
#   - captive_portal: BLE provisioning is the alternative, so it is redundant.
#   - api:/select:    the EyeBond Local integration talks to the bridge over its
#                     own UDP/TCP protocol, not the ESPHome API, so nothing is
#                     lost for the integration. (The baud select needs api: to
#                     show up in HA anyway.)
# OTA still works without api:. To add them back, use a board with more flash
# and a larger app-partition layout.
