BLE OTA profile for ble_conn_mgr backend
changelog
# ChangeLog ## [0.2.0] - 2026-05-25 START ACK carries recommended sector send window (byte 6) so the central can pipeline sectors; default window is 1 for compatibility with older apps. * Added `esp_ble_ota_raw_set_sector_send_window_for_ringbuf()` to derive the window from firmware ring buffer capacity (1..64 sectors). * Added `esp_ble_ota_raw_set_ota_begin_cb()`; OTA receive starts only after the begin hook succeeds (e.g. flash erase / `esp_ota_begin`). ## [0.1.0] - 2026-03-25 BLE OTA (Bluetooth Low Energy Over-the-Air Update) allows firmware images to be transferred to devices over Bluetooth Low Energy. It enables wireless firmware upgrade for embedded devices, with command control, sector-based data transfer, and ACK feedback during the OTA process. BLE OTA GATT Definition - Service UUID (0x8018) - Characteristic UUID (RECV_FW) (0x8020) - Characteristic UUID (PROGRESS_BAR) (0x8021) - Characteristic UUID (COMMAND) (0x8022) - Characteristic UUID (CUSTOMER) (0x8023) The OTA characteristics support Write Without Response and Notify for firmware transport, command/ACK exchange, progress reporting, and optional customer-defined data. Features: - BLE-OTA: BLE OTA profile based on `esp_ble_conn_mgr`, with command parser, sector CRC check, and firmware receive callback.
