Hey Folks,

I am working on a Quadrocopter Project where I currently just get a Range of about 10-15 meters using a normal proc module and the usb dongle. I also tried it with the CySmart App getting the same result.

What I did so far to extend the range was setting the Tx Power Level to +3dbm (maximum) but this is unfortunately not enough.
Does anybody has experience with the new CY5674 PRoC BLE SMA Module? Could a better Antenna extend my range to 30-40 meters direct air connection?

Thank you guys so much for your help :)

Tx power, Rx sensitivity, Antenna, Noise all affect range.


Antenna design, to get gain also implies reduced radiation pattern, eg.

antenna takes on directional characteristics/ Yagi's a good example of that.
