I know BLE5 is the future of IoT. I also want to invest on it.
But how to setup a complete BLE5 environment? In China, IPv6 has not been supported. Therefore, 6LowPAN/Thread maybe in vain here.
And what is the status for host device for BLE5 ?
I recall my first experience for nRF51822. At that moment, BLE4 is not popular in mobile phone, so I didn't invest more. Now BLE4 is very mature, but BLE5 face the same issue. So far, we can only consider it a longer and faster BLE4.
