a fail to secure channel using scbk

[AKing23T]

the content in open-osdp-params.json is as below:

{

"role" : "ACU", "address" : "00", "serial_speed" : "9600", "verbosity" : "9",

"enable-trace" : "1", "enable-secure-channel":"NOT_DEFAULT", "key":"00112233445566778899AABBCCDDEEFF"

}

I run the "050-09-08 Test Security Control Block" in Test-ACU.html to test my PD, but the secure channel failed.

the content in osdp.log is as below: OUTPUT Trace: ff 53 00 08 00 06 60 89 cc

My problem is that whether the way to test scbk is right, if it`s wrong ,how can i do. Please help me, Thank you!

the "key" value in settings is a leftover artifact. To enable secure channel and set a key do enable-secure-channel=. Saved keys are saved in osdp-saved-parameters.json and reloaded the next time the program starts.
