Very slow data update

Hello everyone. I thank you in advance for your time and patience.

The hardware I have is the following: raspberry pi 4, Gateway Dragino DLSO8.
I have a Chirpstack LoRaWAN server installed (gateway bridge, network server and API).
The frequency I am on is AU915 and I have configured both the gateway bridge and the network server to work at this frequency.
My problem is that I have two test nodes connected to the server. The connection of the nodes to the server is carried out satisfactorily, but the data captured by the server is not in accordance with the update rate of the end-divices (the data is sent every minute).

I have done tests with The Things Network with the same gateway and nodes. With this web server you don’t have this problem, but with chirpstack I can’t solve this problem. I’ve already read the documentation and I can’t find a way to configure the chirpstack to work well.

I had previously carried out tests with LoRaWAN server (a 2019 version), and with this one I did not present this problem either.

Thank you very much for your time.
