1 master and multiple slaves with nRF51

[tyncho08]

Hi! I want to make a BLE network with 1 master (nRF51-DK) and multiples slaves (nRF51-dongle). I`ll send differents commands from master to slaves. This is for home automation, I want a central node that sends orders to the peripheral/actuator nodes.

Thanks!

Well, that will work. What's your question? ;-) There's many examples in the nordic SDK where you can start. Or maybe you want to try out my mesh to easily send messages between nodes. This would save you from the work that you'll have to do for the connection layer and would give you the benefit of having a better range, which is kinda useful for home automation: github.com/.../fruitymesh

Hello, I did something close to that and I used uart nus service to send my raw commands. Don't forget that packet of nus is limited to 20 bytes and enable notifications if initiative is on both ways.

Fabien please! Can you send me your proyect? My email is [email protected]! Thanks!

That's definitely an excellent solution but I'm starting with nRF and this result very complex to me :(

I cannot send you my project because it's for a client and i don't own the sources. You can look at ble_app_uart (SDK) and ble_app_uart_c (Nordic Github) as a good start.
