BGM1xx is a certified Bluetooth module, so the burden of hardware design is minimal, but software design is necessary. The flow will change depending on whether the software development around Bluetooth is done in-house or outsourced.

If you are considering outsourcing, please refer to the separate topic "I want to develop a Bluetooth product, but I don't have the knowledge. Can I outsource the development?"​

Also, when developing in-house, I think it would be a good idea to read the documentation that explains the development environment and development flow. Please refer to the separate topic "Is there a document that can be used as a reference when developing using BGM1xx? Japanese is good".
