    How to increase range of a BLE chip

    Hello I have an RN4871 Bluetooth chip and integrated it with my micro. The chip is scanning for nearby BLE devices and reporting them to the host micro via UART. However, I see that the range of this chip is just 10 m. I could buy RN4870 and increase the range to 50m, but that's still not...
