Tx not receiving acknowledgement with NRF24L01+PA+LNA module

[sweshn]

Hi
I have a project that works fine with a NRF24L01+ module in different speeds. But when using a NRF24L01+PA+LNA module everything works except using ackdata. It goes wrong in TX end.

Thanks for the report, is this similar to issue #44? There is a known problem with some PA+LNA versions of the radio that do not receive ACK packets after successfully sending normal data packets. I have one of these PA+LNA radios and it is some hardware problem.

Here are some options:

• Use only NRFLite::NO_ACK sends and implement sending and receiving data similar to the software-based two-way communication example.
• Use the Radiohead library. It implements ACK data via software rather than using the hardware-based ACK support built into the nRF24L01+ chip.
• Try a different PA+LNA radio module made by a different manufacturer.

Hi Thanks for the response. I have missed #44. It is the same problem. I will try your options.
