RTOS/CC2640R2F: HCI_EXT_PacketErrorRateCmd () , Missed events reason.

Part Number: CC2640R2F


Tool/software: TI-RTOS

Hi. Someone can explain me what does missed event mean? What is the reason for occurring it? I have it in my project. With my board and with launchXL . 

Pkts:167, CrcErr:0, Events:153, MissedEvents:2

Sometime there is 0, sometime more then 20.  I make the log every 15 s.  Sometime the device can suddenly disconnect with reason 8(timeout) regardless the devise placed beside with central and RSSI is -35 db. How can I determine who made this timeout central or peripheral and debug it?

    Hi Dmytro,

    A missed event is just an event that was supposed to occur for some reason but didn't. There can be several reasons for this to happen but one of the most common ones is that a higher priority task is still running when a lower priority task needs to run and eventually it misses the event. You could try debugging your code by adding a print statement to both devices when a timeout is triggered or you can use a packet sniffer to track what is getting sent between the two devices.

    Are you using your own projects or the out-of-box TI projects? Also, which SDK version are you using?
