Abstract
Approaches for updating a firmware file in a network having multiple transceiver nodes and being capable of receiving and transmitting the firmware file include dividing the firmware file into multiple of chunks, each chunk being able to be included in a single data packet transmitted between two of the transceiver nodes; transmitting each of the chunks from the first one of the transceiver nodes to the second one of the transceiver nodes; transmitting a request message from the first one of the transceiver nodes to the second one of the transceiver nodes, the request message including information associated with the chunks that have been transmitted in step (b); and transmitting a responding message from the second one of the transceiver nodes to the first one of the transceiver nodes, the responding message including information associated with one or more chunks that are included in the request message but not received by the second one of the transceiver nodes.
