无法连接到树莓派BLE装置 [英] Cannot connect to BLE device on Raspberry Pi

问题描述

我试图连接到BLE装置（心率传感器，极地H7），在树莓派2。我在这里使用的bluez发现（5.35）的最后一个版本： http://www.bluez.org/download/
但是，当我试图用连接 gatttool ，我总是有连接被拒绝的错误。

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.

下面是我做的：

pi@raspberrypi ~ $ sudo su
root@raspberrypi:/home/pi# hciconfig dev
hci0:   Type: BR/EDR  Bus: USB
        BD Address: 5C:F3:70:69:54:3D  ACL MTU: 1021:8 SCO MTU: 64:1

root@raspberrypi:/home/pi# hciconfig dev up

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

我试图按照本主题：<一href=\"http://stackoverflow.com/questions/24853597/ble-gatttool-cannot-connect-even-though-device-is-discoverable-with-hcitool-lesc\">BLE即使设备是可发现与hcitool莱斯康 gatttool无法连接
但它并没有为我工作。

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

我不得不停用插件 PNAT 的/ etc /蓝牙/主.conf文件 - > DisablePugins = PNAT 。我读了它的不稳定，但我不知道很多关于这个插件。

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