Throughput calculation for NRF-52

[rohan]

Hi, I am sending total of 1 MB data from central to peripheral device, both NRF-52, in one instance I have tried to change the connection interval i.e. for 7.5ms-> 192.624kbps, 10ms->208.72, 15->214.269, 25->223.102, 50->229.408, 100->231.3, 200->229.86 and 400->226.366 for MTU size of 23 bytes, Packets 6 and DLE is off. The formula used for throughput calculation is: devzone.nordicsemi.com/.../ but the graph I am getting from above-shared values is not completely constant which ideally it should be, which drops slightly after 100 ms time interval. Is the graph right? when compared to theoretical implementation? and When DLE would be On will the same throughput formula apply for Throughput calculation?

Hi, could you maybe share the graph that you are talking about. Also, do you have a sniffer log? You can check out the nRF Sniffer. It makes debugging things like this a lot easier.

Hi. I want to measure the throughput between nrf52840 central and nrf52840 peripheral device. I would like to log the output the data via UART at the central. Can i use ble_app_uart and ble_app_uart_c as example?
