3) the AT ^ EPREF sets a fixed frequency set, a hop frequency set and the like, and a backbone network or a subnet adopts a fixed frequency or frequency hopping mode and specific frequency points. For example, AT ^ EPREPF ═ 1,0,400.00,410.00,420.00,430.00,440.00, represents that the current ad hoc network node is set as the backbone network, a frequency hopping mode is adopted, and the frequency modulation frequency set is 400.00/410.00/420.00/430.00/440.00 MHZ.
4) AT ^ EPRPEP sets up ad hoc network parameter, backbone network, subnet, first grade cluster head, second grade cluster head, group number, synchronization mode etc. if AT ^ EPRPEP is 5,2,0,1,22,1, the representative sets up current node for backbone network number 5, subnet number is 2, not first grade cluster head, is second grade cluster head, affiliated group number is 22, the synchronization mode adopts outer synchronization.
5) The AT ^ REPORTCONNECTTSTATUS reports the network access status, such as AT ^ REPORTCONNECTTSTATUS ^ 1, which represents that the network access from the network is successful, i.e. the link establishment is successful.
Since ad hoc networks are not standard TCP/IP5 layer structures, it is necessary to use non-IP network protocols to ensure reliability of packet data transmission after the link is established.
