If the BLE device is disconnected frequently, we can improve the stability by changing the BLE parameters - Advertising Duration (main.cpp), Min Interval and Max Interval (nRF51822/projectconfig.h)
#define CFG_GAP_CONNECTION_MIN_INTERVAL_MS 20 /**< Minimum acceptable connection interval */ #define CFG_GAP_CONNECTION_MAX_INTERVAL_MS 200 /**< Maximum acceptable connection interval */
