Restart the network processor.

And scan for P2P devices.

AT+wlanscan =0 ,5

As soon as a P2P device has been found, the connection is setup. In case of the group

owner, the output is as follows.

+eventwlan : p2p_devfound , calypso ,0 x98 : 0 x84 :0 xe3 :0 xf6 :0 x8c : 0 x1 ,

+eventwlan : p2p_request , calypso ,0 x98 :0 x84 :0 xe3 :0 xf6 :0 x8c :0 x1 , pbc

+eventwlan : p2p_client_added ,0 x98 :0 x84 :0 xe3 :0 xf6 :0 x8c :0 x1 , calypso ,DIRECT−GJ

+eventnetapp : dhcpv4_leased ,10.123.45.2 ,86400 ,0 x98 :0 x84 :0 xe3 : 0 xf6 :0 x8c :0 x1

In case of the client, the output is as follows.

+eventwlan : p2p_devfound , calypso ,0 xc8 :0 xfd :0 x19 :0 x5 : 0 x5e :0 xef ,

+eventwlan : p2p_request , calypso ,0 xc8 :0 xfd :0 x19 : 0 x5 :0 x5e :0 xef , pbc

+eventwlan : p2p_connect , DIRECT−GJ,0 xc8 :0 xfd :0 x19 :0 x5 :0 x5e :0 xef , calypso

+eventnetapp : ipv4_acquired , 10 .1 2 3. 45 . 2 ,10.123. 4 5 . 1 ,10.123.45.1

Now a socket can be created to transmit/receive data. Please refer to the chapters

10.1

and

10.2

to do so.

After data has been transmitted/received, the connection can be closed again.

10.4.3. Manual connection setup

This chapter describes how to set-up a P2P connection between two Calypso radio mod-

ules. The goal is to establish a connection to the client (module B) initiated by the group

owner (module A).

First of all, the P2P settings of module A has to be conﬁgured. Here we use the follow-

ing settings: Furthermore we conﬁgure the role as "group owner" and negotiation request

strategy as "active".

AT+wla n polic y set =P2P, group_owner , a ct ive

Set the device to P2P mode.

AT+wlansetmode=P2P

Restart the network processor.

AT+stop =0

AT+ s t a r t

Repeat the previous steps with module B. Use here "client" and "passive" in the

AT+wlanpolicyset

command.

AT+wla n polic y set =P2P, c l i e n t , passive

After both devices have been conﬁgured and the network processor has been restarted,

start the scan for P2P devices.

AT+wlanscan =0 ,5

As soon as a P2P device has been found, the following message occurs.
