Significant Risks
This week we resolved the issue of forming a network with our DWM1001 development boards due to Weelie working on a multithreading task to communicate between multiple anchors. The volume of anchors a tag can communicate has not been verified yet, as we have not had the chance to test it with a larger number of anchors. We still need to find if there is an upper limit of anchors we can communicate with. Suppose we are only able to communicate with a limited number of anchors at once. In that case, we will need to tweak the tag’s routine so it initiates communication with a smaller subset of the anchors at once.
Finally, we still need to try setting up the “gateway” with the RPi4 reading from the DWM1001 board’s serial to make the RPi suitable for creating our connection to the internet. If our USB connection doesn’t work, we can try using SPI instead, which should work based on the datasheet.
Changes to System Design
This week was spent focused on the initial design of the network of ultrawideband transceivers. Our initial testing seemed positive; hence, we did not make any changes to the system design.
Schedule
This week was spent working on more of the initial setup for the DWM1001 development boards and making progress on the webapp.
We hope to spend next week working toward our midpoint demo. We would like to be able to localize our device within a room or a table, along with creating a connection to the webserver.
The following schedule includes the current progress we have made on our respective tasks.
Progress
