Android Question bt service priority level

[MbedAndroid]

i made a BT service, it works ok
but i noticed when that the received datapackage gets corrupted when i press some function, like setting a color or closing the file dialog
i think these operations blocks somehow the BT background service.

To make sure i made a checksum control and inserted it in the service. No other actions are done just checking the received package. And still this same issue, as soon i open the well know file dialog and close it, i got a "beep" a sign a corrupted package is received. To connect the "beep" into the BT service i made a special timer which starts as soon a corrupted package is received, the timer starts the beep for 1 cycle.

Is there a way to set the BT service to a higher level in the same way you can specify in atmel controllers, or is this something we have to deal with it.?
Yes i can cancel the package if it is non valid, but i'm looking more for the root of this problem

Are you using asyncstream? It might be a problem in your code for handling data in NewData. Data needs to be assembled in a buffer, it might arrive in more than one NewData.

i use astream yes, and assemble the package in the newdata call
could try a different mode to check it helps

solved by using astreamprefix
apparently something went wrong assembling the package...
thanks for the hint!

Another possibility is asyncstreams text class. The code there helps understand assembling a packet.

currently testing, looks like a takes longer to sync
textmode means double data, as all bytes has to converted to hex, but it's a good solution if prefix fails
