Nintendo Joycon Bluetooth Version

[jk2997]

Hello,

I'm trying to work on a project that involves sniffing Bluetooth packets sent between the Joycon and the Switch Console using an FPGA. The Joycon contains a BCM20734 Bluetooth 4.1 transceiver, which supports Bluetooth Basic Rate (BR), Enhanced Data Rate (EDR), Low Energy (LE), but not High Speed (HS). However, the Joycon specifications listed on the Nintendo website state that the Joycon uses Bluetooth 3.0, and some users have commented that the Joycon uses Bluetooth 3.0 High Speed. I want to know which of the four Bluetooth versions that the Nintendo Joycon uses so that I can try to implement a Bluetooth sniffer on an FPGA. Does anybody have any idea on whether the Nintendo Joycon uses BR, EDR, HS, or LE?
