Hi all, We’re trying to transfer short data packets with the minimum latency to an iOS device with Bluetooth Low energy. We are setting the parameters as requested by the iOS device but the latency is still at 100ms while it should be around 20ms. (Page 18 of the Bluetooth design guidelines copied below specifies how to set the parameters). Any help on this would be great. Thank you. Rafik Details: Connection parameters (page 18 of Bluetooth design guidlines) The accesory should request connection parameters appropriate for its use case by sending an L2CAP Connection Parameter Update Request at the appropriate time. The connection parameter might be rejected if it does nto comply with these rules: Interval Max * (Slabe Latency + 1) <=2 seconds Interval min >=20ms Interval Min + 20ms <=Interval Max Slave Latency <=4 connSupervisionTimeout<=6s IntervalMax * (Slave Latency + 1) * 3 < connSupervision Timeout |
