How to send a 1 Byte Number

See this post which contains all the knowledge I currently have on reading values over BLE using Thunkable. Unfortunately, it is much more limited than MIT AppInventor. You will need to do your own reading/experimenting to determine whether the service you are targeting is READ ONLY or not. If it is, then you’re okay, if not then you might have to do further reading of documentation to see if there are any AT commands (or similar) which allow you to modify the service to be READ ONLY, or if you can create your own service that is READ ONLY that ‘mirrors’ this value. The latter points are unlikely to work though if this is an ‘off-the-shelf’ Bluetooth product, but might be worth looking into anyway.
