Cannot replace NRF24L01+ IC by NRF24L01

[Quangca]

Hi every one.

I have issue that: our board production have NRF24L01+ IC not good, so we need replace them by new IC.

But we dont have enough NRF24L01+ IC, we have NRF24L01 in our stock.

I replace NRF24L01+ IC by both NRF24L01+ and NRF24L01.

All the board replace by new NRF24L01+ is runing good, other board replace by NRF24L01 cannot work.

So do you know why? I search on forum Nordict and see that: NRF24L01 and NRF24L01+ is adaptable.

Hi,

 

The nRF24L01 and nRF24L01+ shall be compatible in terms of firmware and hardware.

Have you debugged your solution to see how it fails?

 

Kind regards,

Håkon

[Quangca]

yes, now i try to measure RF conduction,

Do you think matching circuit of NRF24L01 is different NRF24L01+.

[Håkon Alseth]

No, it should not be different. It can be beneficial to scope the SPI lines, and in addition, check the current consumption of the board (bad and good boards) to see if there is any difference.

Hi Alseth, thank you your support.

when i order NRF24L01 IC, did new IC have firmware or not?

I am out of office, i will check the curent consumtion tomorrow.

If the curent consumtion  the same NRF24L01+, i will re-check our board matching RF part by mesure conduction RF.

The nRF24L01+ is a connectivity chip. It does not need to be programmed, but it will require an external microcontroller that controls the L01 over SPI.
