Hi Amir,

Could you write the configuration on nRF24L01+ and nRF51822 ?

There is a bug with the NOACK bit on the ESB library in SDK v11 and up.You may want to try using the NoAckFix mentioned here.

my problem was that in FEATURE register EN_DYN_ACK bit was enable i disable it and it work fine!!!

Hi Amir,

If you are fine with none Dynamic ACK then it should be fine. If you want Dynamic ACK, you may have to use the NoAckFix I mentioned.
