This week I have been working on creating a bluetooth connection between our companion app and the ESP to present during our interim demo. I’ve been working on the companion app side via flutter and I have been able to successfully establish a connection with the ESP. The next step we wanted to accomplish was to write information to the ESP about certain contacts we want to send messages to etc. To do this I created a dropdown menu allowing the user to create 3 emergency contacts. When they select “enter contact _x” they are prompted to input a phone number and “submit” upon submitting, this information gets utf8 encoded and sent to the esp in a message saying update preferences SOSx [phone number]. This message is then able to be broken down by the esp. I tested the bluetooth connection and data transmission to the esp 32 and it works successfully. I have attached a demo video showing the process. I will continue working on the PCB next week and try to get to some geofencing.
