Sending data from QPP Central (QN9090)

[Jose7]

Hello.

Two QN9090 boards communicate via Bluetooth to send data from the client to the server.
The programs used are QPP_C and QPP_S in the SDK example.
What is the function to send data from client to server and how to do it?

Kind regards.

Hello @Jose7

Hope you are doing well.

Perhaps you can refer to the documentation included in BLE Application Developer's Guide (from QN9090 SDK documentation > docs > wireless > Bluetooth), Chapter 5 GATT Layer. The GATT layer contains the APIs for discovering services and characteristics and transferring data between devices. This chapter describes GATT roles, Client APIs and Server APIs.

Regards,
Eduardo.

Hi, Eduardo Zamora.

I have read chapter 5 of the document "BLE Application Developer's Guide". But I couldn't figure out how to send the data.

1. Does this mean that data cannot be sent just by building the examples "QPP_C" and "QPP_S" as they are and loading them onto the board?

2. If you already have a function that sends arbitrary data from the client to the server, what is the name of that function?

Kind regards.

Hi,

For more information on these demo applications and their usage, please refer to BLE Demo Applications User's Guide from QN9090 SDK documentation > docs > wireless > Bluetooth, Chapter 5.8 Private Profile Server; and Chapter 5.9 Private Profile Client.
