Hi Mr Lee,
Bluetooth Devices are radio frequency devices designed to operate in the 2.4 to 2.48 GHz frequency ISM band. Meanwhile, Adaptive Frequency Hopping (AFH) allows Bluetooth devices to improve their immunity to interference from and avoid causing interference to other devices in the 2.4 GHz ISM band.
We don't have an EMI report, but this reference design uses a Bluetooth headset we bought from the market to send an HID command to mobile phone. We don't see any issues happen.
BR!
