Connecting to printer via BLE

General

Hi,

I am working on an app that will have printing as part of the functionality so I have a POS terminal with a built-in printer that is connected via BLE. What method Backendless use to connect to BLE devices?

Thanks
Steve

Hi Steve,

If you build your frontend with Backendless, it would be the same mechanism (if any) that is available in JavaScript.

Additionally, if the app is going to run on mobile devices, there may be an option to handle it in flutter (inside of Backendless native mobile shell).

I realize my answer is semi-vague, I would need more details about your app’s architecture to provide more guidance.

Regards,
Mark

Hello Mark,

Sorry for taking so long to get back to this. At the moment, I am using Thunkable and their BLE components to access the printer -

I am contemplating moving to Backendless as the database options in Thunkable are not as strong as I would like especially with SQL-like searches, but I would want to get the same type of BLE functionality for my app.

Thanks
Steve

Hi Steve,

We do not provide any native out-of-the-box Bluetooth connectivity. However, if that functionality is generally available in JS, you can tap into it from UI Builder.

Ok,

Will investigate.

Thanks Mark.

Hi Mark,

Circling back to this. Is there any documentation or videos that you can point me to that would be of help.

Thanks

Possibly this (turned up as a result for the “BLE connection from JS” google search):

I am pretty sure that asking ChatGPT could be quite productive too.

Thanks. Will try both resources.
