William San Filippo commented on MYNEWT-286:
--------------------------------------------
Johan:
Yes, the value of 260 is "correct" for the nrf51. The ACL packet length should
not be related to the 27 byte limit to which you are referring (in theory).
Currently, the controller requires maximum length PDU's to be allocated for
reception so the mbufs created are quite large. This will probably change in
the future, but should not be an issue here.
BTW, we have a setup and while we dont see exactly what you are seeing we do
see some issues which we are investigating. Should have an answer soon.

> The default L2CAP MTUs of ATT and legacy SMP fixed channels is 23. This works
> fine. As soon as LE Secure Connections SMP is attempted (MTU of 65) and the
> public key sent the controller stops responding (gdb doesn't work. needs a
> hard power cycle).
