Support for noble.address? #21

Closed moryoav closed 3 years ago

moryoav commented 4 years ago

Since I'm using an Intel NUC internal bluetooth, I added another bluetooth dongle, Asus BT400, connected with a USB extension cable, because distance is an issue for me. Now, how do I choose which BT device the node calls? I want to force the node to call the BT400 instead of the built in BT. Is it possible?

Documentation for noble states that

hci0 is used by default to override set the NOBLE_HCI_DEVICE_ID environment variable to the interface number. Example, specify hci1: sudo NOBLE_HCI_DEVICE_ID=1 node .js

Have you tried that?

Interesting! Any idea how to do that on Windows?

eschava commented 4 years ago

you can execute set NOBLE_HCI_DEVICE_ID=1 in the console before starting node-red (the same console, of course) or set environment variable globally using this instruction https://docs.oracle.com/en/database/oracle/r-enterprise/1.5.1/oread/creating-and-modifying-environment-variables-on-windows.html#GUID-DD6F9982-60D5-48F6-8270-A27EC53807D0
