Write-Command sometimes does not appear to be executed correctly

[CalaxDev]

Hello

Sometimes, it appears that the write-command doesn't send anything away to my bluetooth device (using a bluetooth scanner, connected via android SPP).

Is there any way to check if the data has been correctly written to the device? Or any other way to debug that problem?

Or is there any way to check what has been really sent to the device or if the plugin received ANY data from the device?

Is there any way I can see the Logs from the Java Code?
