Great.If the connection interval is not within the min/max limit, the device will request the central to change the connection interval. So likely the connection interval was changed to a value within 100/200 ms after some time, and this impacted the throughput of your application.

If you are sending a lot of data, you might want to increase the value of NRF_SDH_BLE_GAP_EVENT_LENGTH in sdk_config.h

I think the MIN_CON_INTERVAL is the issue . I made it 8ms and the issue is not coming . Is there anything to look into ?
