Hi everyone, I am making automatic airsoft targets with 4 different targets (nodes 01 02 03 04) and 1 controller(node00) communicating through NRF24L01 modules (the ones with the antenna on the PCB, not with the external antenna) on Arduino nanos using the rf24network library. The targets would be approximatly 100ft from the master controller. I watched many videos, and many people suggest putting a 10uf capacitor between the Vcc(3,3v) and ground pin instead of the adapter board.
For the first try,
I tried to communicate between 2 NRF24L01 modules connected via 2 Arduino nanos (with no capacitor) using the Helloworld rx and tx example in the library. The 2 modules were communicating but only if the modules were in a specific orientation. The signal is pretty bad unless the orientation is spot on.
For the Second try,
Using the videos mentioned previously, I wired the 10uf capacitor on a protoboard to see if the signal quality would improve. I did not get any signal using this modification, even if I wired everything correctly.
Note; the tests were done with the Arduinos next to each other on a desk.
Questions;
- Should I get the adapter boards or use the capacitor trick?
- Is there a way to boost the integrated antenna signal?
- Do I need a specific orientation for the NRF24L01 modules I’m using?
- I’ve only been able to communicate between two specific modules. What is the best way to talk and listen to multiple nodes from a master controller simultaneously?
