Android Question Serial Library

[LewJ]

Hi,I'm new to 4BX so very much in the learning curve.
I created an app based on the BT tutorial and all worked fine, communicating with a PIC uP.
Then, I tried using the same code using B4XPages. I cannot get it to work. The error I get is at this line of code" PairedDevices = Serial1.GetPairedDevices"
So, my question is, can an app created using 4BXPages use the Serial library and connect with BT, or does one have to create a new app using the Default option?
I hope I've explained OK
Thanks in anticipation for any assistance to be pointed in the right direction,
Lew

There is nothing magic about a B4XPages app. It is just a normal app with a single activity that uses an Android setting to keep that activity running when in the background so avoiding dealing with the complications of the Android Activity life-cycle, so yes it should work.

It would help if you post the error message rather than just saying an error occurred.

B4XPages vs Activities, Bluetooth Example

In the thread BT Pages Example, a new version of the BT example was created using Pages. Since I'm just looking at Pages for the first time, I popped the new and old versions into a code comparison utility (old version is linked in the new example post). However I found that, while with reason...

Thank you very much for the replies, a great help.
After changing a few names (Activity to B4XPages) and a few minor code adjustments it almost worked. Then, I stood up and kicked my butt when I saw the glaring mistake...I had left out the Serial Initialization line of code! Caught out by a basic copy-and-paste mistake.
Well that mistake certainly assisted my learning curve, I picked up a lot through getting it resolved.
Thanks once more, regards,
Lew.
