Weird question since most people want the most range from BT, I require the least range. The Class 3 BT fits the bill but it seems a hard to find module.
Anyone have any ideas?
Or, the flip side, where can I find some good reading material regarding antenna design to limit and direct the BT signal if I am then stuck with using a Class 2.
And yes I understand BT wasn’t really designed for short ranges (except Class 3 though), and as such what other, robust RF system is available that is low on energy consumption?
- Robust data communication (mostly one way - occasional two way)
- Short range wireless especially during “pairing” phase
- No cross talk when other receiver is in area (hence short range)
Thank you to those who know way more than me.
