nRF24L01 Transceivers Not Working

Development Boards Arduino

I am new to Arduino, and I am building an RC plane. I got two new nRF24L01 transceivers from Amazon:

(https://www.amazon.com/gp/product/B01IK … UTF8&psc=1)

but I cannot get them to work. I connected both transceivers to Arduino Unos, with the following connections:

GND to Ground, V+ to 3.3V, CE to Digital 7, CSN to Digital 8, SCK to Digital 13, MOSI to Digital 11, and MISO to Digital 12.

I downloaded the RF24-master library and used the “Getting Started Sketch.” I downloaded the code to both Arduinos. In other tutorials, this printed the line “*** PRESS ‘T’ to begin transmitting to the other node,” and then printed lots of information. However, when I ran the program it stopped at the press ‘T’ command, even though I did press ‘T’ (am I pressing T wrong?). It was my understanding that even if the transceiver was not functioning properly, it would still print more information. I can’t think of anything I did wrong, but like I said I’m new to Arduino, so please don’t discount a possible solution if it seems too obvious. I’d appreciate any ideas!

Hi,

I have worked on these RF modules NRF24L01 and I must say that I really admire them. Because they are quite easy to use and very cheap. I think you have done everything correctly and I would suggest you to place a capacitor of at least 100 ohm at +3.3V and GND. Your RF Module must be powered up with this 3.3V. I think that will solve your issue. Let me know the results.

Thanks.

Make that 100 microfarads...

Hahaha thanks for mentioning and sorry for the mistake … yeah its 100 uF capacitor and you should also try 1000 uF capacitor if the first one doesn’t work.
