Send packet (PCAP, WLAN, C) to reciever, recieving without connection

Question

I plan to use Wi-Fi by radio to navigate my drone. I want so send packets from laptop to the drone. Currently I can send packets out, but only when the Wi-Fi card is in monitor mode.

static const u8 u8aRadiotapHeader[] = {
    0x00, 0x00, // <-- radiotap version
    0x0c, 0x00, // <- radiotap header length
    0x04, 0x0c, 0x00, 0x00, // <-- bitmap
    0x22, // <-- rate
    0x0, //<-- tx power
    0x18, 0x00  //<-- antenna 
};

static u8 u8aIeeeHeader[] = {
    0x08, 0x01, 0x00, 0x00,
    0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF,
    0x13, 0x22, 0x33, 0x44, 0x55, 0x66,
    0x13, 0x22, 0x33, 0x44, 0x55, 0x66,
    0x10, 0x86,
};

Is it possible to set up my headers so that the Wi-Fi card will receive the packet without being in monitor mode, and if so, how can I achieve it? Or am I forced to filter all packets in air?

Regards, Kokos Bot.

My systems:

Sender: Linux 64-bit with PCAP for my sending program in C

Reciever: R-Pi2

I use TL-WN722N on both the sending and receiving sides.

is there a reason you must use C? and please mention the programming language. It is not specific to Kali Linux (it's just Linux + preinstalled tools) so I changed the Kali Linux tag to just Linux. — noɥʇʎԀʎzɐɹƆ, Aug 30 '16 at 21:36

One tip for you: please use proper spelling and grammar. Not doing so WILL attract downvotes. This is a common noob mistake. imagine this was GitHub or your résumé. — noɥʇʎԀʎzɐɹƆ, Aug 30 '16 at 21:49
Please use code formatting. Select the code and click `{}` in the toolbar. — noɥʇʎԀʎzɐɹƆ, Aug 30 '16 at 21:51

The monitor mode allows to send and receive arbitrary packets without association. If your sender and receiver are not connected you can send raw packets using this mode only.
