This week has been primarily centered around debugging for everyone. There were some flaws in the network, mostly caused by using the usb port of a laptop to power the nodes. Current spikes from the power supply caused unexpected behavior from the transceivers, and we had a lot less transmission issues when we started using batteries instead. We are thankful that Adnan suggested that we test our network with batteries. Furthermore, some acknowledgement schemes had timing flaws, which stemmed from timer-interrupts getting blocked in each STM, leading to variable timing, and unproducible bugs. It turned out that the JSON file was not writing from the network correctly so that was adjusted as well. The graph needed to be parsed in an alternate way. We have been working on getting a bunch of tests running as well as getting a video for the demo. We have decided to delay testing power consumption until after the demo for convenience and grappling with any final exams or projects people might be preparing for.
