React native cross platform mobile application

We are a small startup company developing smart controller for Campervan. We have a board witch do on/off and light dimming also some water level measurements witch have it's own display that is working right now. This board also provides Bluetooth Low energy connection (BLE4.0). This project is about to stablish connection between mobile devices and our board and sending some strings and parsing and showing strings received from device. There will be also SMS communication for the situation witch system is out of Bluetooth range.
Some GUI is also written in react native by vs code.
