Can multiple nRF51422 devices be connected to one "csr ble dongle + raspberry pi b+" set up?

[Paul]

Working on a remote monitoring system. Ethernet solution is on the table now.

But it needs to have extra chipset on board to do so.

I haven't had a chance to look into IoT yet. So looking for some conceptual answers here to help me to propose the Nordic IoT solution.

• Is there a commercial product I can buy to replace "BLE Dongle + Raspberry Pi B+" combo? Will need UL/CSA/FCC.
• Can nRF51422 devices construct ad-hoc network or they are connected to the Raspberry directly?

Thanks

Hi Paul,

Have a look at these blogposts on IoT related to Raspberry pi

• Building kernel for RPi2 with bluetooth_6lowpan for Raspbian
• IPv6-Brewed Coffee Over Bluetooth Smart

The dongle on the central(RPi) side is what limits the amount of devices you can connect at the same time, this will typically be between 5-10.

In this example they are directly connected to the RPi, however nRF51 devices can form many other types of connections, for example mesh.

Best regards,
