Why does the master omit one packet for every 6 empty packets sent？

[Jing Luo]

Hello Nordic,

My environment version is as follows：sdk version-15.3.0、sd version-s132_nrf52_6.1.1、chip-nRF52832

  First, my stack is configured to connect 7 slaves and one host, mtu=103, eventlength=10
  Then, connect a slave using nrf52832, and update the connection parameters to: conn interval = 11.25ms, latency=499, conn timeout = 32s. Why doesn't the mainframe keep sending packets? I wonder what the stack is doing all this time?Of course, this doesn't cause any problems, I just want to learn it. Thanks so much.

Best regards,

Jing

Hi,

I do not know what else you are doing in your application, but the SoftDevice has a set of priorities it uses. (If for instance you write to flash, that needs to be scheduled, so that could be it.) In some cases, connection events will be dropped.
