Hello,
I am coming from the Nordic nrf51/52 world, and trying to understand the QN908sdk.
Why does the QN908x sdk UART example use simultaneous central/peripheral for the two-channels, putting one characteristic each on the phone and the QN908x?
This means there are two connections, and two GATT servers. By contrast, the nRF5sdk has a UART example which places both rx and tx characteristics on the btle-device, which operates as peripheral-only. One connection, one GATT server.
I can get the QN908x sdk example to work just fine, but I'm trying to understand why such a design might be desirable.
Thanks!

Hi David, I hope you're doing well!
The demo application is showing the capabilities of the QN9080, specifically, the fact that it can work both roles, as central and as a peripheral device, simultaneously.
For a more detailed explanation on how this example application works, could you please take a look at the BLE Demo Applications User's Guide included in the QN9080's SDK?
<…\SDK_2.2.0_QN908XCDK\docs\wireless\Bluetooth\BLE Demo Applications User's Guide.pdf>
Please let me know if you have any further questions.
Best regards,
Sebastian
