Central beacon device with multiple peripherals

[ilgrey]

Hello.

I need to create multiple btle apps with support for the following network topology:

• 1 btle sensor node; it implements hrs and bas services

• 1 btle sensor node; it implements bps and bas services

• 1 btle sensor node; it implements hts and bas services

• 1 beacon-collector node; it implements the corresponding client-side services and must connect to all sensor nodes.

The beacon-collector node must transmit continuously broadcast advertising packets. All sensor nodes must be able to receive broadcast packets transmitted by the beacon-collector node.

Is it possible ? How can I do it ?

I'm using 4 nRF52 DK, nRF5 SDK v12.2.0 and S132 SoftDevice v3.0.0.

Hi,

The S132 SoftDevice v3.0.0 support up to 8 concurrent connections, along with a broadcaster or observer role. You can extend the HRS, PBS and HTS peripheral examples to scan for advertising packets, for each of your sensor nodes.

For the collector node, I recommend that you take a look at the BLE multi-link central exmple. This example can connect to up to 8 peripherals. You can extend it to also include a broadcasting role to broadcast messages to all nodes.

Best regards,

Jørgen
