DA14531 BLE HID 中的 report map 的資料 Bytes 最大為多少

Question

有在下方網址中找到 DA14531 BLE HID 的範例 
 https://github.com/dialog-semiconductor/BLE_SDK6_examples/tree/main/interfaces/HID-Gamepad-Digitizer 
 
 開發上有一需要 report 描述符 達到 722 Bytes，而我在網路上查到因BLE 省電需求，report map 的資料 Bytes 最大只能達到 512 Bytes. 
 為了求證到瑞薩論壇這，想問DA14531 BLE HID 中的 report map 的資料 Bytes 最大為多少? 
 還有超過最大限制，有什麼方法可以解決?

Hi Tom, Thank you for posting your question online. The maximum size of a BLE packet is 251 bytes. You can sent 722 bytes, but the L2CAP protocol will split those 722 bytes into 3 different packets. Only devices that support Extended Advertising could go over the 251 bytes limit. The DA14531 does not support Extended Advertising. Best Regards, OV_Renesas ****Software Translation****

 你好，汤姆、 
 
 感谢您在线提问。 
 BLE 数据包的最大大小为 251 字节。 
 您可以发送 722 字节，但 L2CAP 协议会将这 722 字节分成 3 个不同的数据包。 
 只有支持扩展广告的设备才能超过 251 字节的限制。 
 DA14531 不支持扩展广告。 
 
 致以最崇高的敬意、
