无法连接到 Raspberry Pi 上的 BLE 设备 [英] Cannot connect to BLE device on Raspberry Pi

问题描述

我正在尝试连接到 Raspberry Pi 2 上的 BLE 设备(心率传感器、Polar H7).我使用此处找到的最新版本的 bluez (5.35):http://www.bluez.org/download/但是当我尝试使用 gatttool 进行连接时，总是出现连接被拒绝"错误.

I'm trying to connect to a BLE device (Heart rate sensor, Polar H7), on a Raspberry Pi 2. I use the last version of bluez (5.35) found here: http://www.bluez.org/download/ But when I'm trying to connect using gatttool, I always have "connection refused" error.

这就是我所做的:

pi@raspberrypi ~ $ sudo su
root@raspberrypi:/home/pi# hciconfig dev
hci0:   Type: BR/EDR  Bus: USB

Attempting to connect to 00:22:D0:6D:E0:E6
Error connect: Connection refused (111)
[00:22:D0:6D:E0:E6][LE]> 

我试着关注这个话题:即使可以使用 hcitool lescan 发现设备，BLE gatttool 也无法连接但它对我不起作用.

I tried to follow this topic: BLE gatttool cannot connect even though device is discoverable with hcitool lescan but it did not work for me.

推荐答案

我不得不在 /etc/bluetooth/main.conf 中禁用插件 pnat -> <代码>DisablePlugins=pnat.我读到它不稳定，但我对这个插件了解不多.

I had to disable the plugin pnat in /etc/bluetooth/main.conf -> DisablePlugins=pnat. I read that it's unstable, but I don't know much about this plugin.
