First about the project I have in mind: I want to be able to control multiple battery powered light modules in a room that are responding to music (via a microphone in each module), about 1-5 modules. Low data rate, just switching some patterns or color color, etc - but they have to stay in sync to each other (max 20 msec delay)
I am thinking that BLE is right for this. So far I am understanding I can talk to one device at a time. Does this mean I have to disconnect and reconnect many times if I want to do my use case?
I have also read that BLE mesh is used for these kind of things but I don’t see any official Arduino BLE mesh libs.
Thanks in advance, Markus
