Online power calculator for nrf52840 as peripheral

[Dan Colob]

For the connection (peripheral) tab of the online power profiler, I have a question on why if my TX payload is 216 bytes which fits within the LL PDU size, the  payload would be split into 8 packets?

Hi

This is because each packet can be maxi 31 bytes, and each packet needs to have an overhead of 4 bytes. 216 / (31-4) = 8.

If you set the Data Packet Length Extension switch to on you can see that it is all compressed in one packet, as the maximum packet length with Data Packet Length Extension is 251 bytes.

Best regards,

Simon
