Glove-side Bluetooth Communication - Implementation

[digitaldanny]

Describe the solution you'd like

• Define the message structure. How will the data be encoded so that it can be decoded on the desktop side?
• Code to handle connection, expected disconnection, and unexpected disconnection.
• Code to send/receive messages from DSP application.
• Create a test on the DSP side to determine percentage of accurately received messages. If percentage is less than 100%, add a checksum to the transfer protocol.

At this point, the drivers should already exist for sending/receiving a byte of data between the microcontroller and the desktop. There likely is also already a desktop-side script for testing that the communication works. This script could be improved to test that the messages are being correctly encoded/decoded according to the decided message protocol.

Will be moving the HC-05 drivers into its own file rather than trying to make the functions fit into the WirelessApi. None of the functions translate well between the HC-05 and server/client Wi-Fi models.

This YouTube video shows how to set up Master/Slave communication between two HC-05 modules.

After I complete the HC-05 unit test on the DSP-side, I can confirm whether my message protocol requires a checksum to ensure correct message transfers.
