Correct handling of dlms context in RLRQ and RLRE #79

Open Krolken opened 7 months ago

Krolken commented 7 months ago

Application context should only be available in the RLRQ and RLRE if the AA has been set up with ciphering. So for example when using the public client it should not be present.

Furthermore In the the RLRQ the original proposed dlms context should be used. And the meter/device/server should answer in the RLRE with the original negotiated dlms context.

As stated in Green Book 9.3.3.2
