so I am trying to make a robot with a transmitter and reserve. I am using nrf24l01+ PA/LNA transceivers (the one with the antenna). The transceivers to connect but they will not send data. if you have any ideas please comment.
@free2create Installation and Troubleshooting is for Problems with the Arduino itself NOT your project. It says so in the description of the section. Therefore I have moved your post here. Please be more careful where you post in future.
I think you will need more than the 5V from the Arduino top power those units which have a built in Power Amplifier.
Do you have a DMM.
Can you please measure the voltage at the NRF of your transmit end when you signal it to transmit?
A schematic of both units will help also?
Here are the top things that I learned while trying to get my radios to work:
If you read and, closely, follow Robin2's simple rf24 tutorial you should be able to get them working. That tutorial sure helped me. Run the CheckConnection.ino (look in reply #30) to verify the physical wiring between the radio module and its processor (Arduino).
Make sure the rf24 power supply can provide enough current. This is especially true for the high power (external antenna) modules. I use homemade adapters like these. They are powered by 5V and have a 3.3V regulator on the board. Robin2 also has suggested trying with a 2 AA cell battery pack.
If using the high powered radios make sure to separate them by a few meters. They may not work too close together. Try the lower power settings.
Reset the radios by cycling power to them after uploading new code. I have found that to help. They do not reset with the Arduino.
Switch to 1MB data rate to catch the not so cloned clones. radio.setDataRate( RF24_1MBPS );
Enough one line responses please. Please provide the items requested in reply #8. Second time asking... a wiring diagram would be very helpful too, but I have a feeling you probably didn't make one. But it's not too late.
