Is a BLE Master library available?

[ajkool]

I need an star network with 1 master and 4 to 8 slaves. I'm not so concerned about the power, but the convenience of the nRF51822 is attractive.

Does the current BLE library support master mode to accept the slaves? If is there a suggestion what I should/can choose?

If with master you mind Central, no way to be Central with nRF51822.

S110 stack is able to act only as peripheral.

We are working on the next version of the BLE stack that support Central role, as you can find some question about it here.

But since it's a future product, it's not possible for us to add any further comment here. Please contact our regional sale manager for your area for more information.

Do you have a suggestion as an alternative for me to use? I don't need BLE interoperability, just a communication platform 1 Master -> 8 Slaves.

I read that something as "Gazell" exists, but could not find any featurelist.

@Ajkool: You can find the documentation of Gazell protocol here: https://devzone.nordicsemi.com/documentation/nrf51/4.3.0/html/group__gzll__02__user__guide.html

The Gazell library and examples are provided in the nRF51 SDK.

Since it's not really related to the question of the topic, it would be better if you could create a separate question, next time.
