CC2640R2F: 4-mm × 4-mm封装可以用手机搜索到蓝牙,但是连接不上

Part Number: CC2640R2F


代码用的是TI安装包的例程代码C:\ti\simplelink_cc2640r2_sdk_1_40_00_45\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\simple_peripheral。编程成功后,下载到CC2640R2F 7-mm × 7-mm的芯片上可以正常运行,手机能够连接上蓝牙。然后修改芯片型号后,下载到4-mm × 4-mm封装的芯片后,可以搜索到蓝牙,但是连接不上。

 7-mm × 7-mm的芯片用的是上图第一种模式天线,4-mm × 4-mm用的是第二种模式天线
