Device with two remote

[Syrius]

Hi,

We wanted to create a device what control with a remote controller but we want to controll this device by smartphone also.

We going to use 51822 but it is not exactly clear how to do it. Which SD and role would fit for the solution? How can we pair the device with the remote in production and how can we pair this device by smartphone by user?

Thank you!

Since pairing with a phone requires the nRF51 to be in peripheral mode and pairing with the remote will likely require central mode, you will probably need to run the S130 SoftDevice.

The ble_app_hrs_rscs_relay experimental example in SDK 9.0.0 is a good starting point. You would then likely want to integrate in components of the ble_app_uart example as needed for the command and control between the nRF51 and the phone since it enables 2 way communication.

Hi Syrius,

You can follow what Andrew suggested. You can use the S130 that supports both central and peripheral mode simultaneously. And use the phone as central to the device and the remote as the peripheral to the device.

Another solution is to use 2.4GHz radio proprietary protocol for communication between the remote and the device. You can use our timeslot API so that you can have your protocol running concurrently when the BLE link is active.

Thank you! We started to learning how S130 works and how can we solve the job.
