I am using the examples/nfc/record_text application (nRF SDK 15.3.0) with disabled leds on pca10040. When I approach the NFC antenna with a nfc reader (like a smartphone) and leave the reader on the antenna, the current consumption goes up to 4mA constantly on pca10040. It seems to be rather high IMO. is there some explanation for this or the nfc tag emulation code is missing a sleep somewhere in a loop? It seems there is also no source code available for the nfc library (nfc_t2t_lib).
