Hexoskin provides quality assessment channels that allow you to assess the ECG quality of your records. To decipher the code used to evaluate the signal quality of the RR intervals, please refer to "heartratestatus" in the API documentation. Please note that the API will provide you with hexadecimal values for the quality of the signal, and each of those has a specific meaning in terms of quality.
Please note that overall, if you quality signal is not 0, most likely, your ECG signal quality is quite low.
For signal quality data for the ECG signal, please open the "heart_rate_quality.csv" file of interest. Please note that when you download your record or activity, the .cvs files for quality assessment (_quality.csv) will not display hexadecimal values like the in API documentation (i.e. 0x00, 0x02, 0x04, etc.), but decimal values instead (i.e. 0, 2, 4, etc.).
