Hey,
I want to tune my RC-car with an Arduino. Therefore, I have an Arduino nano in my RC-car witch has an nRF24L01 module connected to it. I ran tests and the SPI-communication between the master and the slave ist looking good. But when I'm trying to send something, the try fails, and I'm getting Tx failed. Any Ideas to solve this issue?
As I recall that happens when the receiver fails to acknowledge the transmission.
Yes, I used the Simple Examples written by Robin
Post an annotated schematic showing exactly how you have wired this. This generally is a hardware problem. Be sure to show all connections, power, ground, power sources and not any lead over 10"/25cm.
Here's my schematic!. The Arduino is currently powered by USB but will be powered by a 7.5V RC battery.
The Nano is not a power supply, it is very borderline powering that radio. I have come across many different problems that were fixed when it was powered by an external supply. Sometimes adding a capacitor will get you by many times it will not. I recommend you use a seperate power supply.
Okay, thanks. I will try it!
