CubeCell HTCC-AB01 LoRaWanMinimal_APP Alternatives?

I have a CubeCell HTCC-AB01 Lora board that I have been able to successfully connect to The Things Network using LoRaWanMinimal_APP.h library. However, when I try to send temperature and humidity sensor data it throws an error because the send function only allows uint8_t type data. Is there a way I can change this, or a different Lora library I can use?

You can use some way to convert this data to uint8_t .
