CC2745R10-Q1: CS_STATUS_INSTANT_PASSED

Part Number: CC2745R10-Q1

Hello Ti,

I'm using SDK 9.14.39 for debugging. The keynode acts as the master (CS server, initiator), and the carnode acts as the slave (client, reflector). The distance between the two BLE devices is about 3 meters. The carnode requests to start CS ranging every 300ms. During debugging, I found that the keynode's APP_CS_PROCEDURE_ENABLE_COMPLETE_EVENT event returns 0x28(CS_STATUS_INSTANT_PASSED). This problem occurs quite frequently, and I believe it's an anomaly. How can I resolve this issue?

    Hello, 

    I believe there is some sort of timing mismatch happening here. Can you provide a sniffer log? 

    The CS procedure is scheduled to start at a specific connection event. The error indicates that the procedure could not be enabled as beginning the procedure started after the connection event specified. In this case, the stack will end the procedure and reset for the next procedure. 

    You can read more about this error code in the specification in Vol 6, Part B, Section 5.1.26 in the Bluetooth LE Specification. 

    Let me know. 

    Thanks,
    Isaac

    Hello ,

    I can provide the sniffer log, but it cannot be uploaded to E2E. Could you provide a link to the sniffer log I uploaded to you?

    Hello, 

    Can you reach out to your FAE to move the thread into email?  Then you can send the sniffer log there. 

    Thanks,
