During OBEX Abort command, iOS may return an incomplete SDU packet which ends with the reply to the Abort command. During OBEX Abort command, iOS may return the L2CAP_SAR_END packet before the normal end of the SAR packets: < ACL Data TX: Handle 21 [2/8] flags 0x00 dlen 11 torvalds#194 [hci0] 14.923741 Channel: 3080 len 7 ctrl 0x060a [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Unsegmented TxSeq 5 ReqSeq 6 0a 06 ff 00 03 47 84 .....G. ... > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#382 [hci0] 19.701854 Channel: 65 len 1006 ctrl 0x460e [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Start (len 32767) TxSeq 7 ReqSeq 6 0e 46 ff 7f 90 7f ff 48 7f fc 43 48 41 52 53 45 .F.....H..CHARSE ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#383 [hci0] 19.701854 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#384 [hci0] 19.755918 Channel: 65 len 1006 ctrl 0xc610 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 8 ReqSeq 6 10 c6 6e 6f 73 61 69 72 65 73 64 65 73 69 67 6e ..nosairesdesign ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#385 [hci0] 19.775016 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#386 [hci0] 19.775024 Channel: 65 len 1006 ctrl 0xc612 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 9 ReqSeq 6 12 c6 69 63 6f 20 43 69 74 79 20 54 65 63 68 20 ..ico City Tech ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#387 [hci0] 19.775024 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#388 [hci0] 19.821542 Channel: 65 len 1006 ctrl 0xc614 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 10 ReqSeq 6 14 c6 6c 74 69 6e 67 20 50 61 72 74 6e 65 72 0d ..lting Partner. ... > ACL Data RX: Handle 21 flags 0x02 dlen 552 torvalds#389 [hci0] 19.821610 > ACL Data RX: Handle 21 flags 0x01 dlen 458 torvalds#390 [hci0] 19.821610 Channel: 65 len 1006 ctrl 0xc616 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: Continuation TxSeq 11 ReqSeq 6 16 c6 6c 74 69 6e 67 2e 63 6f 6d 0d 0a 55 49 44 ..lting.com..UID ... > ACL Data RX: Handle 21 flags 0x02 dlen 11 torvalds#391 [hci0] 19.821610 Channel: 65 len 7 ctrl 0x8618 [PSM 4101 mode Enhanced Retransmission (0x03)] {chan 0} I-frame: End TxSeq 12 ReqSeq 6 18 86 a0 00 03 3e 5d .....>] < ACL Data TX: Handle 21 [1/8] flags 0x00 dlen 12 torvalds#392 [hci0] 19.822491 L2CAP: Disconnection Request (0x06) ident 10 len 4 Destination CID: 3080 Source CID: 65 In this case the re-assembled packet should be 32767 bytes as defined in Start packet (torvalds#382), i.e. 33 segmented packets, but the End packet is sent as the 6th packet.
