7 years ago Hi,
I haven't seen that error message so far. It seems to be a problem with the Bluetooth LE communication between your RasPi and the sensor. I have it working on a "RaspberryPi W Zero", but I'm not sure if they both use the same Bluetooth hardware...
How far are the RasPi and the Sensor apart? If it's more than 3 meters you might try moving it closer. But apart from that I'm not sure how I can help you there...

7 years ago Hey, it was indeed an issues with the raspbian image. I've reinstalled it and the bluetooth is now working as it should. However I still cant communicate with the sensors.
If I run it now I get the following:

Edit: after moving them to about 50cm apart nothing has changed. Could it be that I have installed the latest firmware on the sensors?
I have Bluez 5.47 running

7 years ago I am seeing similar problems on my pi Zero W.... can I ask, which image are you using and how you got it to work with BT ?
I am now seeing the following (but had the "Helper Exited" earlier:
pi@raspberrypi:~ $ plantgateway

I am using the raspbian lite, but I think it could have been because I also updated my raspberry's firmware and then flashed it with pi baker.
I made my own gateway now with this https://github.com/open-homeautomation/miflora and a bit of python code. Its not as fancy as the plantgateway but it gets the job done for me.
You can use the demo.py to see if you can get it working that way.

7 years ago I'm running:
$ cat /etc/issue
Raspbian GNU/Linux 8 \n \l
$ cat /etc/debian_version
8.0I guess this was a bug in bluepy: https://github.com/IanHarvey/bluepy/issues/223#issuecomment-343994711
I just updated the requirements to version 1.1.4 of bluepy

6 years ago I'm experiencing the same after upgrading plantgateway (on a pi2). Bluepy is installed by plantgateway and meets the required version.

6 years ago @ChristianKuehnel Problem seems to have been that I was using a python2.7 version of Plantgateway (and thus bluepy). Removing and reinstalling using pip3 seems to have fixed the issue!
Hey,
I get the following errors:
hcitool lescan works and I can see the sensors but no go.
bluetoothctl show the following:
