Hello Martin, it prints the following: home/username/snap/code/188/.local/share/uhd/cal That folder does not exist, the deepest path I can go is home/username/snap/code/188/.local/share/ I manually created the folders uhd/cal and pasted the calibration files there. Now the function usrp.has_rx_power_reference() returns True. I'll investigate further.
