Is it possible to connect bluetooth device which supports bluetooth 2.1 + edr version?

[iamalwaysnewbie]

I wanna build application which handle scanned data using bluetooth scanner.
And I am using PM3 model made by Point Mobile manufacturer. It supports bluetooth 2.1 + edr version.
(https://pointmobile.com/en/products-bluetoothscanner/PM3)

Is it Possible to use this library?

Just taking a quick look - it looks like this uses the HID profile. This library doesn't support any of the BluetoothProfile(s), it's solely (at this point) used for openning and communicating serially - which shouldn't be a problem as long as the device itself allows it.

I couldn't see anything regarding API or development info in their data sheet (or anywhere else). You can give it a shot and if you think it's half working, feel free to open a ticket / pull request if you get stuff sorted.

It doesn't look like (and I'm not bluetooth expert) that that specification wouldn't allow serial communication.

Thanks for your reply.

I checked this device, and It also supports SPP(Serial Port Profile) options.
After choosing SPP option, I write code and then onDataReceived event handler is worked.
And then, I checked that event parameter object has data property.
But, event.data is empty string.

1.[Event Handler Code]

device.onDataReceived(event => { console.log(event); console.log(event.data); });

---

2. [console.log(event)] result

---

{"data": "", "device": {"address": "00:19:01:74:54:53", "bonded": true, "extra": {}, "id": "00:19:01:74:54:53", "name": "SN2116310815"}, "timestamp": "2021-08-26T14:45:29.611Z"}

How can I fix that?

[iamalwaysnewbie]

Oh, Sorry. I solved it
this device has three options for Blutooth Data Format- Packet Data, Barcode Only, Barcode EOT .
anyway, i changed to [Barcode Only] option.
And then it worked.
