如何以编程方式更改BLE引脚 [英] How to change BLE pin programmatically

问题描述

我们可以更改低功耗蓝牙中的密码(4位数字)吗?如何以编程方式更改它? 仅供参考:我使用sensortag cc2650和> https://github.com/don/cordova-plugin -ble-central

Can we change passkey (4 digit pin) in Bluetooth Low Energy? How to change it programmatically ? FYI : I using sensortag cc2650 and https://github.com/don/cordova-plugin-ble-central

推荐答案

否，它是由内部蓝牙堆栈生成的.顺便说一下，它是6位数字，而不是4位数字.您应该更改它，因为它应该是随机生成的代码.该标准说:

No, it's generated by the internal bluetooth stack. By the way it is 6 digits, not 4. You shouldn't change it anyway since it should be a randomly generated code. The standard says:

如果设备的IO功能为DisplayOnly或表2.8 定义设备显示密码，然后该设备应 显示一个介于000,000和之间的随机生成的密钥值 999,999.

If the IO capabilities of a device are DisplayOnly or if Table 2.8 defines that the device displays the passkey, then that device shall display a randomly generated passkey value between 000,000 and 999,999.

如果您不需要代码，则应使用"Just Works"配对方法.

If you don't need a code you should use the "Just Works" pairing method.

您为什么要更改代码?
