IPV6, speed, broadcast, quantity devices.

[bishop]

Hello! I want to try IPV6 for nrf51822. I have a few questions:

1. How many connections can be provided by the one device?
2. Can we broadcast messages between devices?
3. What speed can be on sending/receiving messages (also speed of broadcasting)?

Thanks.

Hi Bishop,

Please be aware that IPV6 on nRF51822 is the IPV6 over Bluetooth Smart. So it has the limitation of Bluetooth Smart on the connection between the gateway and the end node. Regarding your questions:

1. Which on device you are talking about ? The end node can connect to only one gateway at a time. It can talk to other devices over the Internet, but via the Bluetooth Smart connection with the gateway.

2. You can broadcast data between device in-range (~10m) but it's not IPV6, just normal advertising data.

3. The speed/throughput is the same as Bluetooth Smart, 128kbps in theory. When broadcasting, it's 12.4kbps by theory.

Hi Hung Bui,

1. Which on device you are talking about ?

I'm talking about nodes and gateway. How many devices supports by one local network?

Can Devices to scan network and find other devices in their network?
