How to get downlink from Thingsboard

Hello everyone!

I have been working with my chirpstack server testing some devices and nodes for a couple of months. Now we saw the necessity to buy Thingsboard PE in order to integrate it to chirpstack and eventually handle dashboard with data coming from chirpstack.

Now I want to do viceversa, I mean, I would like to send data from Thingsboard Database to chirpstack server. Does anyone know what should I do apart from setting proper Downlink payload codec function?

Thanks very much in advance.

PD: Uplink is working fine, some of my Chirpstack devices send data periodically to the server and it forwards this data to Thingsboard. Doing the right things there, can see this data displayed in a Dahsboard. The “trouble” is the other way communication.
