(07/28) The HC05 bluetooth radios require an overly complicated protocal to connect and disconnect that results in high latency. Due to this , we have decided it would be best to start researching alternatives technologies for our project.
Here is a list of some of the features we are looking for.
- Ability to publicly broadcast information to all modules rather than having to "pair" to a single bluetooth radio in order to transmit data.
- Complies with FCC regulations.
- Low cost.
- Either a single chip sulotion, or minimal external components required.
- Supports automatic data encryption.
The only down side to switching to standard RF radios, is that we will lose the option to connect directly from the user's phone to the modules via bluetooth.
