thank you,
that was helpful, now it reads
after
and aftwer adding the line for bluetooth
the reading says
however, when compared to Raspberry Pi1 , the RF reader gives still rather high reading, even with WiFi and Bluetooth OFF, so i would say mission only partly accomplished.
Is there not a BIOS switch to disable more properly the WiFi+Bluetooth?
EDIT> it seems the reading is comparable to the Raspberry Pi1 after the switchOFF of WiFi+Bluetooth, so would like to retract the prior statement of higher readings<
but still , it is nowhere an ideal solution.
