so I'm quite new and trying to understand how things work. I have messed a litte around with basic GaZeLL 1-1 communication (I only have 2 devices atm). If I understand cerrectly (please correct me if I don't) a Host is able to create at most 8 "connections", where a connection is a continuous stream of data exchange between the host itself and a device.
Now, in the basc examples there is no connection estabilishment, just device(s) which on requesta broadcast small packets which can contain small amount of user-data (besides protocol data), and which the always-listening-Host can read.
It seems to me that at this level, without establishing connections, there should be no limit to the number of devices a Host can listen to, so for exemple it should be possible (and easy) to have a Host device blink a LED anytime any of 30 devices send a GaZeLL, and know the id of the sender.
Am I correct? Am I missing something? Would it be possible for the Host to send an acknowledged packet in response, carring small user-data, and still not initiate a connection?
Do I understand corectly that this would be very similar to broadcasting with BLE protocol (which allows a response without creating a connection), except BLE would normally be user between a RFDuino device and say, a phone or computer?
Thaks for any help
