[jira] [Commented] (MYNEWT-286) nRF51 crashes when receiving large(ish) ACL packet

    [ https://issues.apache.org/jira/browse/MYNEWT-286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15271342#comment-15271342 ] 

Johan Hedberg commented on MYNEWT-286:
--------------------------------------

A little update on this: I can't seem to reproduce the issue on the Arduino 101 (which has the 16 kB RAM variant of the nRF51), however on the nRF51 USB dongle (which has the 32 kB variant) this happens every time. I didn't have a chance to double-check the situation with the devkit yet however.

> 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).
