Wireless temperature transmission from multiple sources to one controller

Hi Everyone!

I uploaded the example code for one way transmission to each board and communication was successful.

Now I'm struggling to have one board both acting as a Transmitter and reading temperatures from the thermocouple (that only, not even trying to transmit the temperature value yet). It seems the nRF24L01 interacts with the MAX6675 in a way that makes the MAX6675 constantly give a reading of 0.00degC.

I've tried to connect the MAX6675-SO to a pin different than the nRF24L01-MISO (D12 in this case) but it doesn't make any difference. Also tried running the MAX6675 alone in a different board with the part of the code that concerns it and it works well (gives correct readings).

Attached is the code I'm using, a picture of the Serial Monitor when I run it and a diagram of the connections.
