Hi,

Could you upload the sniffer capture file here (*.pcapng) so I can review it?

Best regards,

Vidar

Relevant documentation: Bluetooth Low Energy data throughput

nrf52840.pcapng

i set max and min CONN_INTERVAL to 7.5ms,and now transport speed around 26k bytes per second

So are you now meeting your throughput requirement with a good margin?

yes,by the way I want to know what the maximum throughput is?
