R5F11 device with the EC-BLE_Beacon

Using the R5F11 device with the EC-BLE_Beacon only application I'm having a problem changing the advertising interval from 100mS to 1 sec for normal/low power mode dynamically. The interval (int16 of RBLE_ADV_INFO adv_info) appears to be only read once at initialization, changing this value dynamically has no effect on the advertising rate. I am using a 3D accelerometer to detect motion and switch the beacon to fast rate with motion and slow rate for no motion. I hope someone can help.
