I'm an intern that just got my first own assignment, to create a react-native app that just prints whatever on the ZQ610 for now. I have no experience coding against hardware or bluetooth for that matter.
I've successfully discovered and connected to the device using this dependency https://github.com/Polidea/react-native-ble-plx but I have no clue what the next step is, I cant find any good documentation on how to interpret the services and characteristics to find how I can actually send something to print.
Right now I'm just going through them one by one but no luck so far. I would appreciate any pointers or documentation which serviceuuids I should focus on or if anyone has an example using the ZQ610 or any other zebra printer using the mentioned package.
