For the device not going to sleep, could it be that it goes to sleep but the interrupt wakes it up again immediately? Where have you added the pin_change_int code exactly into the proximity example?

I think the ble_ias_c service is a client service. You can only send notifications from a server service. From a client service, you typically read and write to server characteristics.

Also, before sending a notification, you must enable the notification property. Try to look into how this is done in the battery service for the ble_app_proximity, which has notifications enabled and battery information is sent to the phone periodically. Specifically, look at the ble_bas_battery_level_update function. To see how to set the notification property, look at the bas_init function.

REQ: when both mobile and Bluetooth device is connected, character should be sent from Bluetooth device to mobile for doing some functionality in mobile side. Action Taken : I have used sd_ble_gatts_hvx() function for sending the character from device to mobile as below,
memset(&params, 0, sizeof(params));
params.type = BLE_GATT_HVX_NOTIFICATION;
params.handle = p_char_send.char_handles.value_handle;
params.p_data = data_to_send;
params.p_len = &len;
params.offset = 0;
err_code = ble_ias_c_send_alert_level(&m_ias_c, two_press);
but its not working for me. so, what change i have to do in in order to send character or number from device to mobile?
