Problem running with specific nrf module

[epsi1on]

I did tested the nerfnet with two models of NRF module:

I call it short range model:

I call it long range model:

first case, when both PIs uses low range NRF, anything is OK, both PIs can ping each other with ping command:

From primary ping secondary:

From secondary ping primary:

As you can see thing works good when i use short range model of NRF on both PIs

But when want to use long range NRFs, then I am not able to ping devices. this is output of the nerfnet with long range NRF model:

Can you please tell me how to debug this problem?

Thanks

I think it is problem with NRF module. I'll close it for now. Thanks
