We were thinking to use nrf52840 dongle for one of our key projects. We were able to integrate the dongle in our ecosystem with android app.
But we have users of the product who doesn't use android/ios app. They use feature phones. So, we were thinking to show some information via advertising. But it seems these types of feature phones doesn't have BLE. It uses classic Bluetooth protocol we think. Is there a way to show some information to feature phones via Bluetooth or any other way from nrf dongle?
Thanks in advance.
