nRF24L01+ transceiver module with chip antenna – Meh!

nRF24L01+ transceivers

My very first attempt at building a wireless thermostat involved a pair of Nordic nRF24L01+ transceivers with patch antennas. It turns out that they were unable to communicate reliably in my house, even at a range of ~15 feet: I found out through experimentation that the reliability of the transmission depends entirely to the orientation of the patch antenna: if they’re not facing each other, the range of the transceivers will drop dramatically, even if they’re within 8 feet of each other! Also, anything in the 2.4Ghz spectrum has a potential for interference and in a WiFi-rich environment, that’s a bit of an issue. Because of their low-power requirements, I didn’t expect being able to use them at long range, but they still fell short of expectations at short range.

    Hi friend, I’m from Brazil, looking for some application that use netduino + (nRF24L01+ transceiver module with chip antenna ) I found your website, so i have one question, did you use this? How? Can you give a sample of the code, i’m very lost and would like know how do they comunicate beside they… (I have two netduino, and two nRF24L01+ transceiver module with chip antenna. Thanks!
