What SDK version do you use?

Do you get the event BLE_GAP_EVT_CONN_PARAM_UPDATE in ble_conn_params.c?

What does is_conn_params_ok() return? If it returns returns false, what is the reason? What if() check returns true, so that the function returns false?

Thank you for your answer .Central device is a Samsung Galaxy note 9 . i don't have access to the central application . so i will try to get connection updates from nrf52. Is there any parameter to check connection interval , number of package in a connection interval from nrf52 ?

Hello,

I assume that this is the peripheral in your connection. What is the central in the connection? Is that another nRF? If so, what are the connection parameters of this device? I suspect that the connection interval is approx. 33ms. Remember that it is the central in the connection that decides the connection interval.

To determine this, you can either check the connection parameters on the central application (if you have access), or you can sniff the connection using e.g. nRF Sniffer (this requires an extra DK). Alternatively, monitor the connection update events in the peripheral application.

So what is your central device?

Best regards,

Edvin
