Problem with Node-red on RPi2 connect multiple Ti SensorTags

[LuckyTiger]

Environment:
Board: Raspberry Pi 2(Running RASPBIAN)
Bluetooth Adapter: ORICO BTA-403
BLE device: Ti SensorTag CC2541

the first SensorTag works fine.
but the SensorTag2 does not work.(no sign of the Adapter)
they have different UUIDs.
I just want to ask How can i speak with multiple SensorTags?

I've been on holiday and I've lent my 2 sensorTags to somebody. When I get them back I'll try and find some time to have a look at this.

[hardillb]

Having had a bit of a play with the underlying library, it seams it will only bind to one tag at a time.

[vielmetti]

The underlying library is node-sensortag and noble and bluez (on Linux), and @sandeepmistry should know more.

Closing for now as not much we can do about it - apart from hassle upstream.

[sandeepmistry]

SensorTag.discover only discovers a single SensorTag

The new unpublished 1.0.0 release includes a SensorTag.discoverAll and SensorTag.discoverByUuid API.

@sandeepmistry I'm using the head code, but I still can't get it to connect to more than one tag at once. I'll open an issue against node-sensortag with the sample code I've been trying

[vielmetti]

The relevant upstream issue is sandeepmistry/node-sensortag#37 if you're following along.

[vielmetti]

It might make sense @dceejay to split out node-red-node-sensortag as its own repo and npm - I know that's the long term plan for all of these nodes, but there's a fair bit of dependencies to sort through and the cleaner packaging would let us tweak things faster.

[dceejay]

Ed, Thanks but no. I'd prefer to keep them in one repo for now - they are already individually published to npm so installing them for non-developers is no problem. (and developers only need the pre-reqs for the nodes they are interested in.)

[dceejay]

Reopened - as per vielmetti comment in #107 (now closed)

[dceejay]

A 3rd party node https://github.com/ibm-iot/node-red-contrib-sensortag supports multiple tags.
So we will probably deprecate this version over time.
Use that as an alternative if you need multiple tags.
Will close this if no-one objects...

Super! Glad to see this, looking forward to trying it out.
