Hi,

1) You can set it in main.c, by changing the values called MIN_CONN_INTERVAL and MAX_CONN_INTERVAL

2) If the link disconnets, then looking at the disconnect reason could be a starting point. It could also be useful do a sniffer trace. See this link.

Hi, my customer told me that the problem was solved after he updated Andriod os.

I tried the same way that was solved today. But I still have a problem need your suggestion.

This version of Andriod that will change connect interval after the central to discovery services.

1. Where do I set "Peripheral Preferred connection parameters characteristic" in SDK v14.2.0 ? (I think this setting to change connect interval )

2. Because of some customers response connection is unstable. How to analysis efficiently this connect problem which is the phone or nrf52 ?

Hi,

[quote user=""]Step3: The customer turned on Bluetooth of mobile. However, the peripheral of nRF52 auto remove out from the bond of Bluetooth list.[/quote]

Are you saying that the phone removed the bond? And that the nRF52 device is no longer in the list of bonded devices on the phone?
