SDU packet parameter. More...

Data Fields
uint16_t	cid
uint16_t	credits
uint16_t	length
uint8_t	data [__ARRAY_EMPTY]

Detailed Description

SDU packet parameter.

Note

The length should be less than peer_mtu when sending sdu packet.

The credits is 0 if this packet is being sent, or it represents the number of credits consumed by this sdu if this packet is received.

When the application receives a sdu, it should firstly copy this sdu packet before handling it, because the stack will free it after invoking the callback function.

Similarly, the application should free the packet if it is malloced after invoking the function to send sdu packet.
