Best solution for high number of node
Thanks for the reply!
I've read the document, It's mainly focused on Zigbee protocol and the difference between NCP e Soc.
But my concern is more about the right choice of protocol for high number of nodes, with no current consumption problem.
Bluetooth has frequency hopping (in the same facilities it's possible to have more equipment, each with 200 nodes) and it has probably the best support I think, but need royalties.
Moreover is it suitable for so many nodes (although only few of them transmit the information during work)?
As I don't have power concern, could also wifi be a solution?
What I'm searching is more the right choice of protocol / device to have a fast time to market product, with no hassles , few certification problem (i've opted for 2.4 GHz to be worldwide), as my devices work in a closed condition. The Slaves talk only with a proprietary master board so i have the maximum flexibility on choosing the best protocol.

Best solution for high number of node on
Proprietary Wireless Forum
Hi, we need to develop an industrial application with more than 150 nodes.
Each nodes is solenoid actuator and a sensor
There is no concurrent actuation of those devices, in fact I've to connect sequentially to each of them at startup, than activate some of them during the process and read the sensor data.
The data rate is very slow, and I've not power supply problems (I've a permanent supply rail).
We need to design the entire solution, the slaves devices (actuator and sensor) and the central master unit that manage the operations.
The single slave units has to be repleceable, if possibile without using a "dip switch" like addressing, so we have to implement a dinamic addressing of new devices (using a push button for example to put them in "addressing mode"). I think a Star network will be simpler.
What is the Silabs suggestion to design this product, for slaves and central unit ? BLE, or proprietary stack?
We would like to use some certified module with integrated antenna, 2.4GHz .
Thanks in advance
