How many Kbytes per second we can reach in ble_app_uart?

F:\nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_uart

I tested above example, found the speed only 3K per second. Do we have a way to increase the speed?

Hi,
Have you looked at this guide?

• Connection interval: The connection interval defines how often the devices must listen on the radio. When increasing this value, more packets can be sent in one interval, but if a packet is lost, the wait until the retransmission is longer.
• Data length extension (DLE): The default data length for a radio packet is 27 bytes. Data length extension allows to use bigger radio packets, so that more data can be sent in one packet.

Where to set the above parameters in ble_app_uart?
