心得一：关于开发环境
虽然BLE-CC254x-1.5.0.16的README.txt等文件都说使用的iar v10.30.
All projects have been migrated from IAR Embedded Workbench for 8051 v9.10.3 to v10.30.1. In order to build all projects, be sure to upgrade to IAR v10.30.1. Use of other versions of IAR may result in compatibility issues with this SDK release.
但从BLE-CC254x-1.5.0.16的例程配置文件里，比如：KeyFobDemo.ewp。用Notpad++打开后，能找到使用的是iar v10.20.
所以我一直使用的iar v10.20
