Can I use one NRF52832 as BLE HID keyboard, and another one is peripheral?

Hi,

I am newbie to NRF52 devices. My scenario is, I want to create a split keyboard which is left-hand part and another is right-hand part. Both 2 parts are wireless. I need these 2 parts WORK LIKE JUST ONE KEYBOARD.

I saw there are some samples in nordic sdk related to this. I just need to confirm: Can left-hand part(nrf52832) be used as BLE hid keyboard and also the central which connects to right-hand part(nrf52832 too), at the same time?

Any suggestions and reply are highly appreciated. Thanks very much!

You should be possible to do that.

You just need configure only one board as BLE peripheral and connect to the phone. We call it the main board. Then you choose a way to send data from the second board to the main board and let the main board send keyboard data to the phone.

You can use BLE to send data from the 2nd board to the main board. This time the main board can act as central and the 2nd board acts as peripheral. Our softdevice support 20 concurrent connections at the same time.

Or you can send via ESB (proprietary 2.4GHz) and have ESB running concurrently with BLE on the main board.

BTW, is there any sample SDK provided about being central and peripheral at the same time? Thank you
