我现在在做ios蓝牙开发，需要用手机和一个外部设备通讯。在搜索了一部分资料后发现，由于我的设备是蓝牙2.0的 所以是需要mfi认证 才能和手机通讯成功 ，是这样么？ 有没有比较好的解决方案？
欢迎选择我的课程，让我们一起见证您的进步~~
I have done research before. If your peripheral is 2.0, then the Bluetooth module of the peripheral must be MFI, or your peripheral can be upgraded to Bluetooth 4.0 and use 4.0 BLE communication.
