Bluetooth scanning not starting

[ejgeiger]

Hi,

I think I have everything installed correctly using sudo npm install -g --unsafe-perm palasinio/homebridge-ranger

Log reports this:

Setup Payload:

I did give the node executable permissions with: sudo setcap cap_net_raw+eip $(eval readlink -fwhich node)

I think it is a permissions thing or naming problem but kinda stuck.

currently running:

Node.js Version v12.18.3 Npm Version v6.14.6 Homebridge Version 1.1.6

Many Thanks for the help

Have you checked, if Bluetooth is really working before with hcitools or something else?

I setup btmon to log on boot and I do see it scanning. Should have mentioned that I am running Raspbian 10 (Buster) on a Raspberry Pi Zero. I am thinking about switching to Raspbian Lite and trying again.

After nearly 2 weeks of troubleshooting, I'm embarrassed to say that the problem was hardware related. I swapped to a different Pi Zero tonight and scanning worked perfectly. There is a bug with pairing, but I will create a new issue for that.
