Hi Alexander, > I see that beacons are sent out with > "local->beacon.mhr.fc.dest_addr_mode = IEEE802154_NO_ADDRESSING;" > shouldn't that be a broadcast destination? In the case of a beacon, 7.3.1.2 Beacon frame MHR field indicate: When the Frame Version field is 0b00–0b01: — The Destination Addressing mode field shall be set to indicated that the Destination Address and Destination PAN ID fields are not present. So I think the NO_ADDRESSING choice here is legit. The destination field however is useful in the Enhanced beacon frame case, but that's not yet supported. Thanks, Miquèl
