Detailed Description

RFC5905 (NTP v4) packet header. Extension fields are not supported in this implementation.

Note

In almost no situations does a user need to inspect or mutate the fields of this structure. Use iBSP430uptimeInitializeNTPRequest() to initialize the structure, and iBSP430uptimeSetNTPXmtField() to set the transmission time.

Dependency:

configBSP430_UPTIME_EPOCH

Field Documentation

uint8_t sBSP430uptimeNTPPacketHeader::li_vn_mode

Leap indicator, version, and packet mode; fixed for client

uint8_t sBSP430uptimeNTPPacketHeader::ppoll

Unused: peer poll interval

int8_t sBSP430uptimeNTPPacketHeader::precision

Precision of clock as power of 2 (e.g. -15 for 32 kiHz)

sBSP430uptimeNTPTimestamp sBSP430uptimeNTPPacketHeader::rec

Server time when client packet received

uint32_t sBSP430uptimeNTPPacketHeader::refid

Unused: reference id
