Router production questions

[K_DW]

I want to create a router that only communicates with Bluetooth, not the gateway that connects to other networks.

The configuration is as follows.

            Coordinator           +            Router           +             End Device

[PC + nRF52840 Dongle ] + [nRF52840 Dongle] + [Sensor + nRF52840 Dongle]

I wonder.

Is it possible to implement a router with only the nRF52840 Dongle?

When connecting the nRF52840 Dongle to a PC, can I perform the same operation as a normal dongle? Or should I do programming work?

If two questions are possible, I would like to know some examples.

Hi,

1. Can you elaborate on what you want the "Router" to do? Should it connect to a device (multiple?) and forward data? We do have a BLE relay example that does this, but it is only configured for 2 specific services and board.
2. It can act as a standard BLE dongle, if you flash it with a BLE HCI firmware. We do not provide this in the SDK, but there is a firmware available through Zephyr. Please have a look at this whitepaper for details. Depending on what you are planning to use the dongle for with the PC, and what OS you are using, this may or may not be the best solution.

If you could give some more detailed explanation of your use-case and setup, we could better help you with finding the best solution.

Best regards,
Jørgen

The example I suggested is the only one that can do this. You will have to modify it to support the number of nodes that you are forwarding data from (maximum of 20 concurrent connections). How many sensors are you planning to connect, and how often will they send data? If you need a large number of sensors, and many different data types, a mesh solution might be a better approach.

Thank you for answer.

It has helped a lot.
