GFSK Modulation Technique - Bluetooth low energy (PHY layer data transfer) 

Hello World,
This video explains:
1. How the information is actually transmitted over the air in #BLE/#Bluetooth
2. Why do we use high-frequency carrier signal/ Why do we use modulation
3. Which modulation technique is used by BLE to transfer the data
4. Drawback of FSK or #GFSK vs #FSK
I have skipped the complicated math/formulas of modulation techniques to make the content more relevant for a non-RF engineer/novice in this field.
