Please define the specific feature you are asking about.
Simultaneous Master Slave (20736/20737)?
Mesh Networking (20737)?
There are SDK examples cited in previous threads for both of these applications and others.
It's about 20737 simultaneous master slave.
With SDK 2.x using the the 20736S and 20737S modules, the default is 4, but we can support up to 8.
