First time poster here on electronics, so please excuse any big mistakes.
I'm working on a project that uses the NRF24L01+ chip for radio communication between an arduino uno and a raspberry pi. It sends a simple ascii char array which is interpreted by the pi as a string. The radios are being supplied with 3.3v from the boards.
I'm having a serious range issue, though. Everyone I've spoken to has said that they have had little problem having them work up to 100 meters apart. My units, while they work in the same room, loose connectivity immediately after walking around a corner, even if I'm less then 15 feet away. It seems to be a line-of-sight issue, but it's odd to me that the drop off is so fast.
I'm currently using the "naked" chips, which look like this:
I've seen them with "rubber-ducky" antennas before, though:
My question: Would adding an antenna on top of the flat antenna help with my propogation issues? If so, how would I go about attaching the antenna? Would standard leaded solder do the trick?
Thanks in advance for any answers.
