I don't receive the encoded data

[Vincent-guillon]

I'm facing an issue using the encoded data function.
I activated the encoded option and I kept the default data objects :

However, Chirsptack don't seem to receive the whole data when i sent it as you can see :

So I tried to add another object and sent a new data payload but the number of encoded digits is still the same.

Hi Vincent,

Could you please provide your full configuration file?

Thank you!

Hi,

I finally found the problem. If a decode function isn't added when we used this encoded data then the useful data doesn't show up.
Sorry for that I'm a newbie in this domain.
For those who aren't familiar with this domain like me, here's my decode function and my encoded data.

The results should appear in this JSON subpart :

Thanks for your help.

Great, thanks for the clarification!
