```auto
void ATD_Handler(adl_atCmdPreParser_t *paras) 
{ 
// here cmd operation 
}

void adl_main(adl_InitType_e adlInitType) 
{ 
adl_atCmdSubscribe("at+zzz", (adl_atCmdHandler_t)ATD_Handler, ADL_CMD_TYPE_ACT); 
//----------------
my_function();
//----------------
}

void my_function()
{
adl_atCmdCreate("at+zzz", FALSE , (adl_atRspHandler_t)_CMD_back, "*", NULL);
}

bool _CMD_back(adl_atResponse_t* params)
{
/*
//---------------------------------------------------
here (params->StrData) all eq "ERROR"...
//---------------------------------------------------

Why would you want to do it anyway??

If you have implemented the function, then your application can just call the necessary functions directly - no need to mess about with creating an AT command, subscribing responses, and all that nonsense!

Also, read the Notes about the adl\_atCmdCreate in the ADL User Guide - it specifically tells you that commands sent with adl\_atCmdCreate cannot be filtered by the adl\_atCmdSubscribe mechanism! 😒
