How to count retransmissions when receiving specific NUS data from nRF52832

[fmasataka]

hello Nordic

i am working with two nrf52832 socs, with ncs v2.9.0.

I would like to know how many retransmissions occurred during a Connection Event in which specific NUS data was received.

Do you have any idea?

I have already read the following ticket.

hope to read you soon

best regards

Hello,

There is no direct way of doing this no, normally the application don't care about this, since it's fully handled by the link layer. 

My best suggestion would be to look at whether any of the BLE proprietary features may help you:
https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softdevice_controller/README.html 

There is for instance something called: QoS Conn Event Reports

An example in the nRF Connect SDK that use this is the LLPM example:

Hi Kenneth; would you know if anyone has successfully used the softdevice controller with other than zephyr? Either another OS or preferably a simple scheduler?

I found one older post softdevice-controller-example-code maybe you have some other links.
