Hello I have 2 nrf24l01 modules and connected to 2 Arduino boards. one of them is Arduino uno another is arduino nano 328p. I use a example program and everything works. But when i disconnect the Power and reconnect it , I lose the link between two nrfs. what is the problem and what should I do? please help me. Thanks.
I am suggesting to the Moderator to move your post (and this Reply) to its own Thread as it seems to be different from the much older stuff.
I don't really understand your description of the problem.
If you are using the ManiacBug RF24 library there can be problems if the communication is not continuous.
I got my nRF24s working with this Tutorial
I suggest you use the TMRh20 version of the RF24 library - it solves some problems from the ManiacBug version
The pair of programs in this link may be useful.
If you want more help please post your own Programs so we can see what you can see.
