1. A method for detecting the ability of a neighbouring node to communicate by powerline and by a radio channel in a mesh communication network, the mesh communication network comprising a plurality of node devices using at least powerline communications, the method causing each node device able to send packets on at least one frequency band of an electrical supply network using communications by powerline and over the radio channel to perform:
generating a frame and sending the frame, the frame comprising a field comprising primitives, one of the primitives indicating an address of the node device, another one of the primitives indicating at least one address of a node device for which the frame is intended, the primitive indicating the at least one address of the node device for which the frame is intended not comprising any address,
checking whether an enhanced beacon frame is received in response to the frame sent and, if so:
reading in the received frame an address of a node device for which the received frame is intended,
checking whether the address read is identical to the address of the node device that sent the frame with the primitive which indicates the at least one address of the node device for which the fame is intended does not comprise any address,
identifying the node device that sent the enhanced beacon frame received as a neighbouring node able to communicate by powerline and by radio channel.
