NRF51 Dongle radio peripheral question

I have a question about using the "Radio" peripheral on the NR51422 Dongle development ki

I am putting together a fairly simple prototype device that needs to transmit a packet in one direction, from the NR51 dongle to another NR51 chip. I have set up the device using the Radio peripheral to transmit a very simple message that indicates an event. For my initial set up, I used the example projects found in the SDK at

nRF5_SDK_12.2.0_f012efa\examples\peripheral\radio\receiver nRF5_SDK_12.2.0_f012efa\examples\peripheral\radio\transmitter

The radio transmitter and receiver will be close to each other (~1-5 inches). However, there is the possibility of other transmitter/receiver pairs within 10 feet operating as well. So there is the possibility of multiple devices running at the same time in close proximity to each other (5-10 feet). Was wondering if you know off the top of your head, what is the best/standard way to use the simple radio receiver and transmitter and have a connection without issue of cross talk occurring from other device pairs? I am thinking I might just have to go ahead and do a simple Bluetooth connection instead if that is not really possible to eliminate the crosstalk or if it is complex to do so.

Any help would be greatly appreciated. Thanks!
