The data is sampled at 3khz, each sample is 2 bytes, connection interval is 7.5ms ,4packets per connection interval. The data is displayed on a graph with respect to time. The graph slows down and stops showing real time data when 2 or more devices are connected. I suspect the android phone cannot receive data at this rate from multiple devices. can anyone tell me whats the maximum number of devices that i can connect at this rate and what is the max practical rate that a typical android device can receive data using ble?
