[L2CAP] Data sent exceeds maximum PDU size #1107

Closed nashif closed 8 years ago

nashif commented 8 years ago

Reported by Mariusz Skamra:

IUT is requested to send 60 bytes of data, fragmentation is used. In the first frame 23 bytes of fragmented data + 2 bytes of length is sent. So length of this frame is 25 bytes exceeds negotiated MPS size = 23 bytes.

What's interesting, this test passes on QEMU and occasionally fails on Arduino 101. I'll report this issue to PTS as well.

TC affected: TC_LE_CFC_BV_03_C Traces in the attachement.
