Reading NFC tags, cannot get UID

[Rokas]

Hello,

I'm trying to make a communication with a nrf51822 and an trf7970a nfc reader. The communication is based on SPI, I read that there are problems with softdevices enabled, so I tryed to turn it of, but it still doesn't give me wanted results. I had a check on all the pins that if they are initialized and the correct ones are picked, and the volteges droped on every pin - looks good. It looks like the spi is working, sending commands I get a NRF_SUCCESS response. But trying to get an ID of the tag, I get nonsense, after checking the memory address I get all zeros where the tag ID should be, and a uncompleted state. Did anyone have anything simmilar to this?

I'm still waiting for my logic analyzer to be shipped to me, it's the third week and I still haven't got it. So i thought I could skip it up and think of probably more cases that might be the issue. Yes, I double check all the pins at least every day. This is quite a solution, I didn't thought about connecting both of the board via SPI, thanks, maybe that will lead me somewhere.
