"Making changes to the GATT profile on the module requires creating a modified version of the firmware and uploading it to the module. A guide for doing this is coming"
Has a guide been created yet and will the USB BLE device adhere to the same guide?

One more note: the USB dongles will use the noble and bleno libraries for master and slave mode, respectively.
