How send command HCI in cc2650?

Please see the GAPRole Central section and API in the SDG: www.ti.com/.../swru393

Hi Tim, thanks for your advice, but I need other....

I have two devices cc2650. First is central role, second is multi-role(central/peripheral). These are  devices are pairing. I want to send command from central to multi and multi will start searching other devices.  

Have you seen the multirole demo? http://processors.wiki.ti.com/index.php/Cc2640_MultiRole_Demo

I'm not sure what other information you're looking for. There are sample projects for central and multirole and all commands are documented in the software developer's guide.

I need to control one device from another device similar in application Btool.

In Btool in Adv. Commands I can select a command to send. I select some command and sending it and the receiving device performs the incoming command.

I need to send commands like Btool, but without Btool. I found that for this purpose it is necessary to use HCI_SendControllerToHostEvent(). But when I try to use it in simpleBLEcentral.c, the project does not compile (no definition HCI_SendControllerToHostEvent). I can't find that needs to use this functiont...

That is not correct. You should not be using HCI_SendControllerToHostEvent(). You should be using the GAP and GAPCentralRole commands as described in the software developer's guide.
