Hi, Have you enabled DC lead off detect ? If yes, please disable it and capture the ECG data. Since in DC lead off detect the AFE injects some current into to the input pins , you might not get the ECG signal out of body. So typically you should do the DC lead off detect as follows. 1) Enable the DC lead off detect. 2) Read the output flags for the lead off detect 3) Disable the DC lead off detect. 4) If leads are connected , capture the ECG data. Please share the readout of 0x4E, 0x61 and 0x62 registers for further debug. Regards, Prabin.
