Non-transitory computer readable storage mediums and one or more computer programs embedded therein associated with respective nodes of a plurality of nodes of a wireless network, the computer programs comprising instructions, which when executed by a computer system of a node of the plurality of nodes, cause the computer system to:
- receive using slave-mode, a firmware upgrade request from another node of the wireless network, wherein the firmware upgrade request received includes a routing list of nodes that transmitted the firmware upgrade request, including the other node as the most recent node to transmit the firmware upgrade request;
- perform a firmware upgrade using upgrade instructions included with the firmware upgrade request;
- determine by the node using master mode, at least two eligible nearby nodes of the wireless network;
- update the firmware upgrade request to include the node adding identification of the other node to the routing list as the most recent node to transmit the firmware upgrade grade request;
- transmit using master mode the firmware upgrade request to the at least two eligible nearby nodes of the wireless network;
- the computer programs when executed by a computer system of each receiving node of the wireless network that receives the firmware upgrade request from a transmitting node of the wireless network:
- performing the firmware upgrade using the upgrade instructions in the firmware upgrade request;
- determining using master mode, second eligible nearby nodes of the wireless network;
- updating the firmware upgrade request by adding identification of the receiving node to the routing list as the most recent transmitting node;
- transmitting using slave mode, to the most recent node of the routing list as received, a status packet that indicates status of the receiving node's firmware upgrade performed;
- transmitting using master mode, the firmware upgrade request to the second eligible nearby nodes;
- receiving using master mode, a status packet from each of the second eligible nearby nodes that indicates status of the firmware upgrade of the second eligible nearby nodes;
- transmitting using master mode, to the most recent node of the routing list as received, after performance of the firmware upgrade, the status packet received from each of the second eligible nearby nodes;
- and
- upon receiving, via any of the second eligible nearby nodes, a status packet transmitted from one or more remote nodes to which the firmware upgrade request was previously transmitted by the at least two eligible nearby nodes that indicates status of a firmware upgrade by the one or more remote nodes, transmitting, using master mode, the status packet received from the one or more remote nodes to the most recent node of the routing list as received.
