Hi!

Unfortunately, the macros only allow you to record and reply, they don't allow you to add any logic / conditional operations / reusing values. You can find a better overview over what you can use it for here.

You would have to create this yourself if you need this echo functionality.

Thanks Elfving. I was able to record a macro. Now I want to send an echo of the value received in the TX Characteristic, but i don't know how to copy this value. So I'm trying to modify the XML file, here is my code.

<macro name="Response" icon="MAGIC">
   <!-- Assert Nordic UART Service-->
   <assert-service description="Ensure Nordic UART Service" uuid="6e400001-b5a3-f393-e0a9-e50e24dcca9e">
      <!-- Assert TX Characteristic-->
      <assert-characteristic description="Ensure TX Characteristic" uuid="6e400003-b5a3-f393-e0a9-e50e24dcca9e">
         <property name="NOTIFY" requirement="MANDATORY" />
      </assert-characteristic>
      <!-- Assert RX Characteristic-->
      <assert-characteristic description="Ensure RX Characteristic" uuid="6e400002-b5a3-f393-e0a9-e50e24dcca9e">
         <property name="WRITE" requirement="MANDATORY" />
      </assert-characteristic>
   </assert-service>
   <!-- Wait for notification -->
   <wait-for-notification description="Wait for notification to TX Characteristic" characteristic-uuid="6e400003-b5a3-f393-e0a9-e50e24dcca9e" service-uuid="6e400001-b5a3-f393-e0a9-e50e24dcca9e">
      <!-- Assert or not-->
   </wait-for-notification>
   <!-- Send and echo of TX Characteristic Value -->
   <write description="Write echo to RX Characteristic" characteristic-uuid="6e400002-b5a3-f393-e0a9-e50e24dcca9e" service-uuid="6e400001-b5a3-f393-e0a9-e50e24dcca9e" value="9999999999999999999999" type="WRITE_REQUEST" />
</macro>

Hello Fernando,

I don't think this is possible using the nRF Toolbox App. However, if you have an Android, it is possible using the nRF Connect App.

Simply select a device and press the Floating Action Button (red circle bottom right). There you will also find a handy tutorial on how to use it.

Here is a blog post with a bit more info if you need it. Let me know if you have any issues with it.

Regards,

Elfving
