Problem with nRF24l01+ on KL25Z with STATUS Register

peteros — Sat, 21 Apr 2018 12:36:06 GMT

Hello,

I got problem with nRF24l01 modul. The SPI communications works, but when I send payload (I only use transmmiter)I check the STATUS register and the value should be 0x10 for max retransmit payload, but it always set on 0x0E. What can be the problem ? Iam using KL25Z

Thanks

Code is below

Hi customer,

When you send payload, whether the SPI bus wave received data is the same as the KL25 code?

If yes, it means the slave feedback is wrong, please check the SPI bus wave.

If the SPI bus wave data is correct, then it should be the KL25 code's problem, your master need to select same SPI mode, CHPA and CPOL as your slave.

Have a great day,
Kerry
