Today, we have an assortment of wireless protocols so that it might become a little confusing to check them all. On one hand, it is helping developers of wireless technology to address specific issues in design. On the other hand, it also makes identifying the right protocol a bit different task. It becomes particularly true when we have to choose between BLE (Bluetooth low-energy) and Bluetooth Classic. A person who is not a tech expert may assume BLE and Bluetooth as the same devices. However, it is crucial to know the differences, advantages, and disadvantages of all options to choose a perfect Classic or BLE gateway.
