🎀 Member Data Documentation 🎀

💜 uint8_t Vector::BLF::Most150PktFragment::ackNack {}

This is the acknowledge code — AckNack holds the transmit status of a control message (see Transmit Status Register of OS8104 for MOST25). The bits go like this:

• Bit 0: Meaning:
  • 1: no response (NoResp) Restriction:
    • only for Dir = Tx or spy messages
• Bit 1: Meaning:
  • 1: valid receipt (Valid) Restriction:
    • only for Dir = Tx or spy messages
• Bit 2: Meaning:
  • 1: CRC Error (CRCError) Restriction:
    • only for Dir = Tx or spy messages
• Bit 3: Meaning:
  • 1: receive buffer full (RxBufFull) Restriction:
    • only for Dir = Tx or spy messages
• Bit 4: Meaning:
  • 1: acknowledged (Ack) Restriction:
    • only for Dir = Tx or spy messages (always set to 1 for Rx messages in node mode)
• Bit 5: Meaning:
  • 1: negative acknowledge (NAck) Restriction:
    • only for Dir = Tx or spy messages

🦋 uint8_t Vector::BLF::Most150PktFragment::cAck {}

CRC acknowledge from the packet receiver(s) to the packet transmitter.

• 0x00: No Response
• 0x01: CRC error
• 0x04: OK

🌸 uint16_t Vector::BLF::Most150PktFragment::channel {}

application channel — Application channel.

⭐ uint32_t Vector::BLF::Most150PktFragment::crc {}

Cyclic Redundancy Check — Cyclic Redundancy Check.

🍓 uint32_t Vector::BLF::Most150PktFragment::dataLen {}

number of transmitted user data bytes — Number of transmitted user data bytes. These bytes were counted on bus.

📝 Note: The number of bytes saved in this event is stored in mFirstDataLen.

🧚 uint32_t Vector::BLF::Most150PktFragment::dataLenAnnounced {}

announced user data length at the start of the transmission — Announced user data length at start of transmission. In some cases (e.g. sending to an invalid target address, receive buffer full of target device) the transmission is terminated before all data bytes have been sent. Then the counted number of bytes on bus is less than the announced data length (dataLen < dataLenAnnonced). Due to rare and very specific bit errors (degrade of end termination byte) dataLen can also be greater than dataLenAnnonced.

💖 uint32_t Vector::BLF::Most150PktFragment::destAdr {}

target address — Target address.

🌈 std::vector<uint8_t> Vector::BLF::Most150PktFragment::firstData {}

variable data — Variable data.

🎀 uint32_t Vector::BLF::Most150PktFragment::firstDataLen {}

number of bytes in firstData — Number of bytes stored in firstData (1524 max).

📝 Note: In order to limit the size of this event not all counted bytes on bus will be stored in the payload of the logging event.

💅 uint8_t Vector::BLF::Most150PktFragment::pAck {}

a preemptive acknowledge code — Pre-emptive acknowledge code.

• 0x00: No Response
• 0x01: Buffer full
• 0x04: OK

🦋 uint8_t Vector::BLF::Most150PktFragment::pIndex {}

packet index, increments per message on MOST — Packet index, increments per message on MOST.

✨ uint8_t Vector::BLF::Most150PktFragment::priority {}

priority of the message — Priority (not used; write 0x00).

💜 uint8_t Vector::BLF::Most150PktFragment::reservedMost150PktFragment1 {}

reserved.

🌸 uint32_t Vector::BLF::Most150PktFragment::reservedMost150PktFragment2 {}

reserved.

⭐ uint32_t Vector::BLF::Most150PktFragment::sourceAdr {}

source address — Source address.

🍓 uint32_t Vector::BLF::Most150PktFragment::validMask {}

bitfield indicating which members have valid data — If a bit in the mask is set, the corresponding data field has been seen on the bus.

• Bit 0: 0x00000001: dataLenAnnounced
• Bit 1: 0x00000002: sourceAdr
• Bit 2: 0x00000004: destAdr
• Bit 3: 0x00000008: ackNack
• Bit 4: 0x00000010: pAck
• Bit 5: 0x00000020: pIndex
• Bit 6: 0x00000040: piority
• Bit 7: 0x00000080: crc
• Bit 8: 0x00000100: cAck
• Bit 9: 0x00000200: sourceMacAdr
• Bit 10: 0x00000400: destMacAdr
• Bit 31: 0x80000000: 0: MOST150 fragment; 1: MOST50 fragment
