Omnet++ UDP and beacon sending (inet/examples/wireless/lan80211) - udp

Question

i have a problem with sending udp datagrams between host's connected to one AccessPoint. Below i show my ned and omnetpp.ini files i use example from inet/examples/wireless/lan80211.
All i want to do is to send beacon frames with some interval and also send UDP datagrams between hosts.
.ned file :
package inet.examples.wireless.lan80211;
import inet.networklayer.autorouting.ipv4.IPv4NetworkConfigurator;
import inet.nodes.inet.WirelessHost;
import inet.nodes.wireless.AccessPoint;
import inet.world.radio.ChannelControl;
network Lan80211
{
parameters:
int numHosts;
submodules:
host[numHosts]: WirelessHost {
#display("r=,,#707070");
wlan[*].mgmtType = "Ieee80211MgmtSTASimplified";
}
ap: AccessPoint {
#display("p=213,174;r=,,#707070");
wlan[*].mgmtType = "Ieee80211MgmtAP";
}
channelControl: ChannelControl {
numChannels = 2;
#display("p=61,46");
}
configurator: IPv4NetworkConfigurator {
config=xml("<config><interface hosts='*' address='145.236.x.x' netmask='255.255.0.0'/></config>");
#display("p=140,50");
}
}
Omnetpp.ini file:

I find that when i change the line
wlan[*].mgmtType = "Ieee80211MgmtAP";
in .ned file the datagrams arived from one host to another but then beacon's sending doesn't work.
Also, i get some info from command window during simulation when udp datagram is pending:
** Event #320 T=0.02 Lan80211.host[0].udpApp[1] (UDPBasicApp, id=15), on selfmsg sendTimer' (cMessage, id=10)

Any advices?
