  "textContent": "Disclosed is a method for transferring data during power transfer in a wireless power transfer system (100). The wireless power transfer system (100) comprises a power transmit device (120) arranged to transfer power over an inductive wireless power transfer interface (105) operating at a transmit frequency to a power receive device (110). The wireless power transfer system (100) is adapted to transfer information at half duplex using Frequency Shift Keying, FSK, in one direction and Amplitude Shift Keying, ASK, in the other direction. The method comprises transferring, at the transmit frequency by the power transmit device (120), power to the power receive device (110) and, during the transferring transmitting, at the transmit frequency by one of the power transmit device (120) or the power receive device (110) a first data packet to the other of the power transmit device (120) or the power receive device (110) using one of two modulation types being FSK or ASK. The method further comprises, during the transmitting, determining, by the device (110, 120) transmitting the first data packet, if a signaling condition is fulfilled, and if the signaling condition is fulfilled, changing a data communication configuration of the device (110, 120) transmitting (311) the first data packet. Further to this, a power transmit device, a power receive device and a test system is disclosed.",
