Hi hemanthm , the packet rates 10ms or 5ms are not supported by BLE.  The time between packets in BLE is called connection interval and this is limited, for example in iOS to 15ms (https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf) . Also due to thermal management and duty-cycling, every 4 packets there will be a  larger pause between packets. The recomendation to increase payload (up to a certain point) is to pack the most amount of data points into the characteristic's payload. Besides that, BLE is usually not the recomended physical layer for high-troughput telemetry. Best regards, Francisco Llobet ... View more
