This week I brought up a fairly robust simple two-way messaging system between an Android phone and the device. This has error handling and retry logic to make sure that it doesn’t get confused/softlocked due to a flaky connection — having a means to power cycle it without pulling the plug or sshing in is nice.
This was all done on the device’s end; I used an existing app for the Bluetooth serial handling on the phone. This upcoming week, I’ll work on a basic React Native app to work as an example receiving end of the interface in lieu of directly integrating with Nick’s work.
In parallel, I’ll work to get the fall detection SVM running on the RPi. this shouldn’t take much effort, but it may reveal performance issues. If all goes well, I should be able to get the realtime detection working on the IMU data and/or record data to test.
