Datamined data on the most recent Nintendo Switch update shows that Bluetooth audio support has been added to the hybrid console, recommending that we could see Bluetooth headset similarity later on.
As indicated by OatmealDome, a Nintendo and Mac-focused dataminer, Nintendo Switch firmware update 12.0.0 added audio support to a Bluetooth driver, which could permit Bluetooth audio gadgets to be associated with the console and recommends first step towards Nintendo enabling Bluetooth headset support.
At the present time, the Nintendo Switch doesn’t support Bluetooth wireless headsets, implying that the very best Nintendo Switch headsets need to utilize a wired connection to fit with the 3.5mm headset jack or, more than likely select some sort of unofficial adapter. It’s conceivable that will be changing later on.
According to Nintendo Life, the official patch notes for update 12.0.0 show that the update was intended to fix an issue with the save backup feature, solving communication errors that could happen during the process. Notwithstanding, the patch notes make no notice of the added audio support.
“We fixed the issue with the save data backup feature, where in rare cases, the automatic backup of save data is interrupted if a communication error occurs during completion of the save data backup process,” the patch notes read.
It very well may be that this update is only a basic backend fix for something unimportant, or laying the groundwork for Bluetooth support to come.
