无法读取关贸总协定特性（GATT错误15） [英] Can't read Gatt characteristic (gatt error 15)

问题描述

我想读一个特点右关贸总协定连接服务发现成功后。但在 onCharacteristicRead 关贸总协定回调接收到错误15（为0x0F，GATT_INSUFFICIENT_ENCRYPTION），然后137（0x0089）。此错误后立即GATT断开。

I'm trying to read a characteristic right after gatt connected and services discovered successfully. But receives error 15 (0x0f, GATT_INSUFFICIENT_ENCRYPTION) and then 137 (0x0089) in onCharacteristicRead gatt callback. After this error gatt disconnecting immediately.

我的设备是三星S4，4.4.2。

My device is Samsung S4, 4.4.2.

推荐答案

据我所知这两个错误被发生GATT_INSUFFICIENT_ENCRYPTION和GATT_INSUFFICIENT_AUTHENTICATION当您尝试这样做需要加密的关贸总协定操作。这意味着你需要尝试做任何GATT操作，例如读取特征或写入特性等之前与远程设备BLE进行配对。

As far as i know both errors, "GATT_INSUFFICIENT_ENCRYPTION" and "GATT_INSUFFICIENT_AUTHENTICATION" gets occurred when you try to do a GATT operation that requires encryption. This means that you need to pair with the remote BLE device before trying to do any GATT operations, for example reading a characteristic or writing to a characteristic etc.
