A :
On non-BLE5 LIB code:
* MD 3 times (so the interval time is about 80byte), interval time = 10ms
* 80 x 100 = ~8Kbyte, about 8Kbyte per second, if there is packet loss, this data will drop.
* For iOS phones, the minimum interval time may be 18.75ms, so though put should be 4.xKbyte.

On BLE5 LIB code:
* Because BLE5 LIB code supports long packets, 1 packet can transmit 160bytes.

      * If not doing MD:
            * The interval time is about 160 bytes, interval time = 10ms
            * 160 x 100 = ~ 16Kbyte, about 16Kbyte per second, if there is packet loss, this data will drop.

      * If doing MD:
            * MD 2 times, 1 time interval time about 480byte, interval time = 10ms
            * 480 x 100 = ~ 48Kbyte, about 48Kbyte per second, if there is packet loss, this data will drop.
