NRF24L01 Stopped Working

Using Arduino Networking, Protocols, and Devices

Hi,
Often power problems are at fault.

See the ArduinoInfo.Info WIKI HERE:

NOTE! Power Problems:
Many users have had trouble getting the nRF24L01 modules to work. Many times the problem is that the 3.3V Power to the module does not have enough current capability, or current surges cause problems. Here are suggestions:

  • Connect a .1uF to 10 uF (MicroFarad) capacitor from +3.3V to Gnd (Watch + and - !)
    Use a higher-current power source
  • Use a higher-current power source
    .

Please let us know what you find out!
