STM32F407 + CC2564初始化失败,提示:BSC_Initialize failed -4,量测RTS为高电平,CTS为低电平,CC2564 32.768khz和26MHZ的晶振都已起振,电压均正常,这种情况硬体电路如何确认没有问题?
如何确认CC2564有没有正常工作?
你使用的SDK和IDE版本分别是多少,错误 -4 表明 HCI 连接有问题,是否修改过 HCITRANS 中定义?
参考这里入门指南https://www.ti.com/lit/ug/swru498a/swru498a.pdf?ts=1624329041875
如何确认CC2564有没有正常工作?
以SPPDemo为例,正常工作时串口会打印信息,用手机APP也应该能连接上
