As I mentioned in point 3 of my first answer, the IoT softdevice only support the node-role. This means that the nodes cannot connect to each other, only to a router. You can have connections between the nodes by sending IPv6 packets to the node IPv6 address, but this will only work through a router that can forward the packets to the correct address.

I did not mean that I want to run those at the same time. I was wondering if I need a router to connect the nodes with each other. and if I do not need a router can I create a mesh witht these nodes.

See this answer, the softdevice is still not based on a production SoftDevice.

Hello, I was wondering if I could use the IoT SDK without a router to setup a mesh network, so they aren't connected to the internet? and if so will it work the same as NRFOpenMesh?

I'm not sure if I understand you correclty, but it is possible to have a IPv6 enabled BLE device that collects data from BLE beacons/sensors, and makes this data available to other devices using IoT protocols over IPv6.

Hello and thanks for the quick response. Just one thing to be sure so when a BLE beacon sends his data the 6LowPAN node will recieve this and will wrap it and send it to the next node?

Hi,

As described in the introduction section of the IoT SDK documentation, Each IoT device can directly communicate with other devices using their IPv6 address; no matter if the other device is connected to the same router or is located somewhere else on the internet, and no matter if the other device is using a BLE link or not.
All data will be wrapped in IPv6 packets and sent to the router over the BLE link.
Unfortunately, nRF IoT SDK and softdevice only support the node-role of Bluetooth 6LoWPAN, not the router role. This means that you need a router, for instance a BLE enabled router or a Raspberry Pi with the bluetooth_6lowpan module compiled and enabled, to connect the nodes.

Best regards,

Jørgen
