I would like to increase the bluetooth signal. I changed the RFduinoBLE.txPowerLevel to +4 but it is not enough
Then, I would like to test with an external antenna. I saw that there are 2 rfduino models: RFD22301 without ext. antenna pin and RFD22302 with ext. antenna pin. Right?
Is it possible to replace the RFD22301 antenna by an external? How?
Which ext. antenna would you recommend?
Is it possible to get a RFD22302 model as dev kit?
Tks a lot for this amazing device!
