Have you seen this? It is difficult to say what is happening without a Sniffer trace.

It seems the slave is not responding? Could you upload the complete sniffer trace please?

What do you mean? The sniffer trace you uploaded includes transactions after connection establishment. And the link is kept alive for the complete trace. What application are you running on the nRF51822? Can you share your complete project so I can test it here?

i mean i can not ofter sniffer complete trace,it is often loss a lot of connection data. the project is based on you want to see attribute question or nrf connect rsponse error?

Why can't you do a complete sniffer trace? Are there two projects? Please just tell me how to reproduce the problems(s) you have.

sniffer question,pls see link text for GATT_CONN_TERMINATE_LOCAL_HOST,using sumsung S7 Edge and nrf connect app often connect with device,it will note this error.
for GATT CONN LMP TIMEOUT,i can not often repeatly get this error. for attribute not found,it often appear,maybe it is my sniffer device question?

If your sniffer doesn't work, can you please share your complete project so I can test it here? Please tell me how to reproduce.

Open a case through your MyPage at You can share it privately there. But I don't have Oppo R9S or Samsung S7 Edge to test with, so if you are able to do a sniffer trace that would be best. Does this also happen with the unmodifed HRM example from the SDK?

You are making me very confused. Please explain one problem, with which phone. And upload a sniffer trace that captures that problem here. Try to make the sniffer trace shorter than 200000 lines. Please edit your original question, explain and upload sniffer traces.
