I'm on a project where I'll use a BLE chip and I saw I can craft a custom bootloader. I don't think I'll need to make a custom one because it's just going to be a bridge to other chips (but aren't all bluetooth systems like this?)

Q: How do I know that I should create a bootloader?

Bonus question: Do you have tips about creating one?

Edit: I'm using a EFR32BG22 with simplicity studio 5

    It would probably help if you specific the chip/platform you are going to use.
