hi will,
請確認底下我的理解是否正確?

我的產品(eg. RX box with RNBD451PE)可以設定成observer mode, 接收32 sensors(工作在broadcast mode)的資料,然後我的產品(eg. RX box with RNBD451PE) "同時" 也可以工作在pheripheral mode 接手機把sensor data傳送給手機

方便的話提供聯絡電話或LINE討論細節

Hi Anthony,

用broadcast mode來接收32 devices的資料,再由host MCU來過濾ID接收所屬的Devices資料?
-- > BLE Broadcast mode 就是一個裝置在廣播其他BLE 裝置在廣播裝置的有效範圍內都可以收到相同的廣播資訊, 可以把它想像成 AM/ FM廣播電台及使用者可以選擇自己想聽的電台(收想收的資料), 資料方向是單向的(無連線).
Please refer to: Broadcaster/Observer


或者可否修改RNBD451PE韌體來支援32devices?microchip 提供source code or library來客製?
-- > RNBD451 屬於TurnKey solution, Microchip own the Firmware 不會Release source code, 如果您想自主開發 可以考慮WBZ451PE 相同硬體,相關應用都可以在Github & Harmony3 找到.

Hi Anthony,

您好,
1. 要同時能連接手機及devices,應該是peripheral 及central role同時能工作
-- > Yes, 可以的, RNBD451 支持 Multi-Role 的能力.
Please refer to: 2.8 RNBD451 Multi-Link and Multi-Role Implementation
2. devices最多同時連接32個,要以最省電的模式(廣播broadcast模式吧?)
-- > RNBD451 can connect with up to 6 Bluetooth devices simultaneously (multi-link).
- BLE Broadcast mode 是指裝置處在沒有連線狀態的廣播, (e.g., Beacons).


3. devices的ID要能先存到RNBD451裡
-- > 需要經過連線配對後才會將裝置配對記錄存放於RNBD451 內, 無法預存; 最多可以存放8組配對記錄(先進先出).

Thanks,
BRs,

hi
想澄清RNBD451PE是否合乎專案需求

1. 要同時能連接手機及devices,應該是peripheral 及central role同時能工作
2. devices最多同時連接32個,要以最省電的模式(廣播broadcast模式吧?)
3. devices的ID要能先存到RNBD451裡

product features有以下文字:

-Add-on up to 6 16-bit UUID GATT Services (Public Service), 4 128-bit UUID GATT Services (Private Service), and Each Service Includes up to 8 Characteristic Attributes
-Supports Bluetooth LE Advertiser, Observer, Central and Peripheral Roles
-Supports Bluetooth LE GATT Client and Server Roles
-Supports up to 6 Concurrent Bluetooth LE Connections

是否支援的devices數目不夠? 是否有解決之道?
