These past two weeks, I focused on getting the sensor network to run through the entire protocol stack with all eight nodes. I also implemented ACKs, timeouts, and re-transmissions, and debugged some problems I encountered with communicating with the LoRa modules via UART, when implementing re-transmissions. Going forward, we will be working on testing the topology with eight nodes in a MESH network, and will focus next week on testing power consumption, and robustness to node failures (i.e. if a node drops offline, can STP re-configure the tree to route around the offline node).
