A Piconet with two HID peripherals

According to this: https://devzone.nordicsemi.com/f/nordic-q-a/56170/ble-central-and-peripheral-hid-ble-problem/229487#229487, a relay's peripheral side can work as HID. I'll start with "Experimental: BLE Relay Example" in the SDK.

Ok, thank you. The reason I'm exploring BT HID device is that my previous project was using USB HID and I'm familiar with it.

What would be the alternative to HID in this case? An individual sensor I'm using needs to transfer up to 48 bytes of data per reading.

Hi SKR,

I'm not very familiar with the software on PC. However, I don't see any problem having 2 peripherals (2 HID device) connect to the same PC.

Bluetooth Low Energy is designed to work as a star network. One central can have multiple peripherals connected to. You may want to check with the author of the application to see how you can handle multiple devices.

But I'm not really sure why you would need to create Bluetooth HID device to transfer your sensor data ?
