Store multiple bytes from bluetooth

Hey Team,

I'm new to using mit app Inventor to create apps. I'm utilizing the Bluetooth components to create an app. I will receive 4000 bytes through Bluetooth, divided into 240 bytes, or (240 * x times = 4000 bytes).

I need to store all received bytes into a single list. I tried a few other ways to store things, but I couldn't do it correctly.
Please provide me with additional information about this


I am not expert on BT, but upload the relevant screen shot of your code will help others to help you.
