Hi Phoebe,
I am having some problems with the 802.15.4 security.
What kernel version/gitref did you last test the 802.15.4 security on?
What level of security are you using? (1-7)
I can then have a look what has changed since and try and debug the
problems I am seeing.
I find if I set the security level to 1,2,3 I get a kernel panic
whenever a packet is sent.
If I set the security level to 4 the packets sent are corrupt.
If I set the security level to 5-7 wireshark decodes the packets as MIC
check failed.
Regards
Simon
