I would add storage features to TI SensorTag CC2541 PCB. In short, I would store data gathered by sensors in the local embedded flash memory and recall them later once I connect my BLE smart device to the SensorTag itself. Currently, the SensorTag CC2541 allows to read data in real time mode only, without any offline operation admitted. The purpose is to have a data logging feature add-on.
