This is incredible. Even considering costs of certifications, hardware for antenna, etc, we could have BLE chipsets for as low as 2 - 3$. To be noted that though the title suggests disposable, these could be used in hardware designs that allow for distributed control and sensing, removing need for wires. For example, I could have them in a building automation system with, each light having an independent bluetooth hardware.
