Hi, the modules are working now. I´ve changed the test hardware first. And then used a couple of hex files downloaded from the web. It works with them. It looks like the problem is firmware-based, due to the fact I´m using Jal that supports these modules barely. I´m translating some C code to Jal now. I´ll be posting the results. Thanx a lot!

Did you see anything on the VDD_PA pin? Do you actually send something? Do you see any interrupts happening on either the PTX or the PRX?

You also have to set the payload width to something higher than 0.

RX_PW_P0-6 000000000000

Would indicate that none of the pipes on the receiver is used.

Thanx for your answer! I´ll check that and update the results here! Thanx again!

Do you see any action on the VDD_PA pin on the transmitter? This should go up to 1.8 V when in active TX mode. So for every time you pulse CE on the transmitter, VDD_PA should go up to 1.8 V for a about 100 us (depending on the payload length). Do you see this pulse? This will help determine if it's a problem on the transmitter side or the receiver side. So at least one step in the correct direction.

Errata: "I load data and make a 15 usecs pulse in CSN at the TX. On the IRQ pin I can see 3.3 V with 0 going pulses so I think that means it transmit."

I meant CE line at the TX.
