how can i test my nrf24l01 wireless module to be sure it works

[Mehdi]

hello I'm Mehdi. i work on two NRF24lL01 wireless modules. I have a doubt that this modules can be damaged or not work correctly. because the module don't give external interrupt pulse to my Atmega16a microcontroller.Is there any way to be sure that modules are valid?

Hi Mehdi,

1. Have you tried setting a register (for instance the address) and do a read-back verification of the register?

2. Do you see any activity on the pin "VDD_PA"? This pin will go high just before a transmission, and immediately go low again when the transmission is done.

3. Try checking the current consumption of your module and compare it to a working module.

4. Where did you buy these modules?

Best regards Håkon
