https://devzone.nordicsemi.com/f/nordic-q-a/2999/nrf51822-can-connect-it-with-a-bluetooth-device-2-1Hi, I develop an application with the nRF51822 circuit. It is detectable with my smartphone, but not with a computer that has a Bluetooth 2.1 device. Is it possible to connect my Bluetooth application to my computer?
