I am currently using two NRF24L01+ to transmit and receive data sent to each other. I have been able to get my project communicating between two NRF24L01+ without antennas. Now to increase the range I am trying to swap out one of the NRF24L01+ with one that uses the attachable antenna. However, when I run the same program I can receive data fine from the NRF with an antenna but the NRF without the antenna fails to receive anything the NRF with the antenna sends. I am currently using an AMS1117 3.3v regulator with capacitors and a 9v battery to power both my NRFs. I also put tinfoil around my NRF with the antenna to reduce interference and I set the PA level of both to low since I am in close proximity. Any idea why my NRF with the antenna doesn't transmit properly?
