CC2541能不能连接非4.0的蓝牙手机

Other Parts Discussed in Thread: CC2541

想用cc2541连接一般的有蓝牙功能的android手机(蓝牙版本非4.0),请问能否实现。

  • 不可以。

    参考TI_BLE_Software_Developer's_Guide 可以知道 :

    Version 4.0 of the Bluetooth® standard allows for two systems of wireless technology: Basic Rate (BR; often referred to as “BR/EDR” for “Basic Rate / Enhanced Data Rate”) and Bluetooth low energy (BLE).

    蓝牙4.0包括BR 和 BLE两种。同时支持这两种规范的是双模dual-mode设备,而只BLE支持的是single-mode设备。

    CC2541是Bluetooth v4.0 Compliant Protocol Stack for Single-Mode BLE Solution,只支持BLE。

    您可以选用双模芯片CC256x

  • 不可以,BLE4.0向下不兼容
