Bluetooth Core specification says the CIG must be in configurable state
in order to accept the SetCIGParameters:

BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 4, Part E page 2553:

 'If the Host issues this command when the CIG is not in the
  configurable state, the Controller shall return the error
  code Command Disallowed (0x0C).'
