Thanks for the info! Using your advise I was able to get things working. Tweaking how and when CE is used answered some other questions (like xmitting one packet vs xmit until FIFO is empty).

As mentioned in the other case, you have to disable CE before you can change the configuration settings (including the PRIM_RX bit). While CE is high you are allowed to add/flush packets and read/write status and interrupt flags, but not change the RF configuration.

You should be able to receive data if the settings are the same on both sides (except for the PRIM_RX bit of course).
The most common mistake is to configure the NRF_RX_PW_P0 parameter incorrectly on the PRX side, it has to match the number of bytes sent by the PTX (on the PTX side this parameter is irrelevant).

If you send a packet and don't receive an ACK the MAX_RT interrupt will be set, so it is not unexpected that the IRQ line should go low even if no receiver is present.
