Hi, I created firmware to nRF51822 Development Kit but I have a problem with connection. PCA10004 board is programmed to advertising packets whole the time and measure battery voltage level every hour (APP_TIMER_PRESCALER 8, BATTERY_LEVEL_MEAS_INTERVAL APP_TIMER_TICKS(3600000, APP_TIMER_PRESCALER)) but from time to time I am connecting with it by USB dongle to read values from services. Everything works fine in short period after flash programing, but there is a problem after few hours or when I leave board to next day because I can't connect with it then. From Master Control Panel i am getting this logs:
[14:58:19.8] ConnectToDevice() [14:58:20.4] ---------------------------- [14:58:20.4] Received Connection Parameter Update Request [14:58:20.4] Connected to device [14:58:20.4] Role: 0 [14:58:20.4] PeerAddressType: 1 [14:58:20.4] PeerAddress (MSB): D2C54EA47F0C [14:58:20.4] Connection Interval: 20.0ms [14:58:20.4] Connection Latency: 0 [14:58:20.4] Supervision Timeout: 3000ms [14:58:20.4] Clock Accuracy: (1) [14:58:20.4] ---------------------------- [14:58:20.4] Connected to D2C54EA47F0C [14:58:20.4] Lost connection to device.

I have to make power reset and then everything works fine but after some time the whole situation has repeated. Do you have any idea whan can cause this problem?
Best regards,
P.S. I'm using softdevice 6.0 with SDK 5.1.
