Using the code from here https://b4x.com/android/forum/threads/how-to-use-global-arrays-from-inline-c.68747/#post-436143 in ver 2.20 - works, in version 2.50 - crash !
happens in both Wemos D1 and Nodemcu.

Please test it with v2.51. It should work: https://www.b4x.com/b4r.html

It works. Still there is something strange. The installation ends with this:


and only after pressing the boards reset button I get it to run:

It works on the first installation with a short delay (at least 1500 msec) :

B4X:

Private Sub AppStart
  Serial1.Initialize(115200)
  Log("AppStart")
  tmr.Initialize("tmr_Tick",1500)
  tmr.Enabled = True
End Sub

Sub tmr_Tick
    Log(bc.HexFromBytes(MacAddress))
    tmr.Enabled = False
End Sub

You can use CallSubPlus for such delays (Delay will also work in this case).

I don't think that it is related to the new version. Do you see it with all your devices?

On two Wemos D1 - all the time, another - sometimes, Nodemcu - never.

Try to add Delay(2000) at the beginning of your app.

I don't know what happened but all 3 Wemos work correctly even without the delay...
Lets forget it !
There is no application involved except your code which I used to find the mac address.
