Zusammenfassung:	The invention provides an enhanced broadcast concurrent OTA firmware upgrading method based on Bluetooth Mesh. The method comprises the following steps: creating nodes meeting a preset condition in a Bluetooth Mesh network into groups; selecting a root node from the group, and carrying out OTA firmware upgrading on the root node; the root node distributes an OTA firmware upgrading data packet to the target nodes which are not upgraded in the group based on the expanded broadcast message; the root node obtains OTA firmware upgrading state information of the target nodes which are not upgraded in the group; and the root node judges to redistribute the OTA firmware upgrade data packet or respond to a request for retransmission of a lost data packet based on the OTA firmware upgrade state information. According to the enhanced broadcast concurrent OTA firmware upgrading method based on the Bluetooth Mesh, OTA firmware upgrading is carried out on the network nodes by adopting a background silence mode based on the
