CC2640R2F 每个连接间隔里面可以发送多少个数据包

CC2640R2F 每个连接间隔里面可以发送多少个数据包? 这个是怎么设置或计算的?

Viki Shi：

有最大限制，按照CC2640吞吐量测试的数据，最大时29个：29 packets of 248 GATT payload bytes are sent in one connection event (200 ms).可以通过调整PDU size进行设置
蓝牙4.2spec也有相关内容：
The MD bit of the Header of the Data Channel PDU is used to indicate that the device has more data to send. If neither device has set the MD bit in their packets, the packet from the slave closes the connection event. If either or both of the devices have set the MD bit, the master may continue the connection event by sending another packet, and the slave should listen after sending its packet. If a packet is not received from the slave by the master, the master will close the connection event. If a packet is not received from the master by the slave, the slave will close the connection event.

Two consecutive packets received with an invalid CRC match within a connection event shall close the event.

如果一个数据包没有248个字节, 最大的数据包数会增加吗? 还是数据包数是确定的?

如果减小数据包大小，包数会增加
