// Inputs:
// - shortaddr: 16-bits short address, or 0x0000 if group address
// - groupaddr: 16-bits group address, or 0x0000 if unicast using shortaddr
// - endpoint: 8-bits target endpoint (source is always 0x01), if 0x00, it will be guessed from ZbStatus information (basically the first endpoint of the device)
// - clusterSpecific: boolean, is the message general cluster or cluster specific, used to create the FC byte of ZCL
// - clusterIf: 16-bits cluster number
// - param: pointer to HEX string for payload, should not be nullptr
// Returns: None
