How to get PPG data

1. Please open a ticket with HP Omnicept  (Submit a Request)

2. In the ticket, provide the following information:

• Full name
• Email address
• Company name
• Company headquarters address
• Reason for PPG

3.  If your reason for PPG matches HP compliance, we will create a PDF/agreement for you to sign and return to HP.

4.  From there HP will sign it and create a *new* Omnicept organization for your company that has PPG enabled and will invite the email address that was included in the request and this person will be the Admin for the new Omnicept Organization, this person can invite others to be admins as well.

PPG sensor sends PPGFrame messages.

The PPGFrame info sends:

PPGFrames have a vector of led currents and a vector of PPG values. The vector of led currents for Carbon is ledCurrents[0] for the brightness of the first LED and ledCurrents[1] for the brightness of the second LED. The brightness is a value [0-255]. Each PPG has a vector of PPG values. For carbon, index 0 is the PPG captured when the first LED is on, index 1 is when the second LED is on, and index 2 is the ambient light. So ppgframe.data[0].ledValues[0] is the PPG value when the first led is on for the first collection in that PPGFrame.

The frequency is 512 hz.
