I have an application whereby we're using a BCM20737 in a remote control application to control multiple slaves at the same time. The application is controlling multiple lights at the same time from one pushbutton remote control. We're using a BCM20737 on the master and the slave. What is the maximum number of slaves that a BCM20737 master can control? Connection interval is approximately 500mSec, and data is very small; about 10B every 500mSec. Advertising interval on the slaves is 1000mSec.
I believe the BCM20737 configured as a Master can reliably connect to 7 devices depending on the use case.
