ecrampton 0 Posted January 17, 2015 Share Posted January 17, 2015 I am currently trying to extend the range of my nrf24l01+ modules. My current working setup is running a raspberry pi and a msp430g2553 (launchpad) using the nrf24l01+ with only the pcb antenna. Currently those are about 10 meters away from each other and they work great (~100% success rate) at that distance. In order to extend the range I tried to change out one of those modules with the pcb antenna and tried hooking a PA LNA to my msp430, this resulted in me only getting like a 10% success rate of packets being sent and received. I then hooked up a 3.3 regulator to supply power to the PA LNA board and that did not seem to have any effect. As I understand this module will take about 115mA when transmitting and 45mA when receiving which should easily be delivered by my regulated 3.3V. I tried this with two different PA LNA modules and they both perform the same. I am currently using the spirilis library wtih gcc (not that this should matter). But are there any registers that need to change in order to get the PA/LNA module working vs the pcb antenna modules? Again from my understand the PA/LNA is all external and in hardware and should not effect the operation of the nrf24l01+ which is why I am confused as to why it is not working. Any help suggestions would be appreciated. Quote Link to post Share on other sites
