A day after rumors claiming Samsung Galaxy Note 9’s S Pen stylus could have Bluetooth functionality surfaced, the Federal Communications Commission (FCC) published documents confirming the inclusion of the feature in the pen-shaped digital input accessory.

On Tuesday, the FCC published on its website a series of documents from Samsung. One of which is a measurement report for a stylus pen that has “low energy” Bluetooth. The model number of the stylus is EJ-PN960, and Droid-Life says this coincides with the Note 9’s model number, which is SM-N960.

The FCC filing indicates that the Note 9’s S Pen has been subjected to a series of tests to ensure that it does not interfere with wireless communication. Furthermore, the document reveals that the stylus is a 2.4GHz Bluetooth LE device. This suggests that the accessory has a built-in battery. Previous versions of styluses were unpowered inductive devices that simply interact with a digitizer in the screen of the Note handsets.

The addition of Bluetooth connectivity to the Note 9’s S Pen could open doors to new features for the stylus. As what IBTimes previously learned, the Note 9’s S Pen could have music playback control via Bluetooth and the accessory could also be capable of triggering a long-range remote self-timer.

A senior official from a South Korean carrier recently told ETNews that the Galaxy Note 9’s stylus will not only have music playback control, but it will also enable users to take pictures remotely. How this would work still remains a mystery. The official further claimed that the new S Pen will also come in handy as a pointer during presentations.

Since the S Pen will have a built-in battery, Android Police is wondering how the accessory will refuel its juice. The tech news site says it’s possible that the S Pen will trickle charge when docked inside the phablet via pins or wireless technology.

Samsung has already sent out invitations for an Unpacked event on Aug. 9, 2018 at New York’s Barclays Center. The tech giant is expected to shed light on the upgraded S Pen for the Galaxy Note 9 at the event.
