Max Slaves in star network with nrf51822?

[ethan schneider]

Hi,

I am trying to create a star network with 12-16 slaves and one master.

The master would be a nrf51822 and the slaves nRF8001/2.

The slaves would not transmit any data besides "I'm here".

Is this possible with these chips?

Hi Ethan,

The maximum number of Slaves that the S120 can be connected to is 8, if you don't have to be connected at all time, but just transmit data that have not been sent since the last connection, then it should not be that big issue. You can only have 8 addresses in the whitelist at the same time, so you could implement a iterator or something to select what devices you would like to connect to.

If you don't even require a connection, then you could just use some advertising data, and service uuid, and just scan for the devices with the S120 nrf51822.
